Mapping land-use and land-cover changes through the integration of satellite and airborne remote sensing data.

An integrated, remotely sensed approach to assess land-use and land-cover change (LULCC) dynamics plays an important role in environmental monitoring, management, and policy development. In this study, we utilized the advantage of land-cover seasonality, canopy height, and spectral characteristics to develop a phenology-based classification model (PCM) for mapping the annual LULCC in our study areas. Monthly analysis of normalized difference vegetation index (NDVI) and near-infrared (NIR) values derived from SPOT images enabled the detection of temporal characteristics of each land type, serving as crucial indices for land type classification. The integration of normalized difference built-up index (NDBI) derived from Landsat images and airborne LiDAR canopy height into the PCM resulted in an overall performance of 0.85, slightly surpassing that of random forest analysis or principal component analysis. The development of PCM can reduce the time and effort required for manual classification and capture annual LULCC changes among five major land types: forests, built-up land, inland water, agriculture land, and grassland/shrubs. The gross change LULCC analysis for the Taoyuan Tableland demonstrated fluctuations in land types over the study period (2013 to 2022). A negative correlation (r = - 0.79) in area changes between grassland/shrubs and agricultural land and a positive correlation (r = 0.47) between irrigation ponds and agricultural land were found. Event-based LULCC analysis for Taipei City demonstrated a balance between urbanization and urban greening, with the number of urbanization events becoming comparable to urban greening events when the spatial extent of LULCC events exceeds 1000 m2. Besides, small-scale urban greening events are frequently discovered and distributed throughout the metropolitan area of Taipei City, emphasizing the localized nature of urban greening events.

Amplitude modulation in turbulent boundary layer over anisotropic porous wall

In this study, the amplitude modulation effect in a turbulent boundary layer over anisotropic porous walls is investigated experimentally at the Reynolds number based on friction velocity of Reτ = 236–319. The streamwise and wall-normal velocity fields were measured using time-resolved particle image velocimetry. To clarify the coherent structures related to the amplitude modulation over the porous wall with skin friction reduction effect, the large-scale structures are extracted from the low-pass filtered streamwise velocity fluctuations. The small-scale events related to high fluctuation energy are detected by the variable-interval space-averaging technique. Over the porous wall, the induced upwash and downwash motion leads to a notable suppression of large-scale structures. The small-scale motions in the near-wall region are mainly caused by the ejection events, while the sweep events are significantly suppressed. The amplitude modulation effects indicate that the positive and negative large-scale velocity streaks produce suppression and enhancement effects to the near-wall small-scale turbulence, respectively, which is contrary to the conventional phenomenon over the smooth wall case. The interaction between outer large-scale and inner small-scale structures is significantly weakened by the porous wall, contributing to the overall skin friction reduction.

Running toward Sustainability: Exploring Off-Peak Destination Resilience through a Mixed-Methods Approach—The Case of Sporting Events

The sustainability of tourism activities faces many challenges. Furthermore, in the context of the Sustainable Development Goals (SDGs) and their overall slow progress, tourism-related goals and targets are underachieved. To address these challenges, this study has recognized sporting events as an opportunity to enhance the socio-economic activities in tourism destinations during off-season periods. More specifically, the aim of this study is to explore the dynamics of off-season destination resilience through small-scale running events, focusing on three key aspects: the strategies employed by organizers, the synergy created within the community, and the sustainable outcomes. Drawing on insights from qualitative interviews with twenty-five running event organizers across Greece, supported by the Delphi method to confirm and validate the results, their perceptions of the economic and socio-cultural dimensions are explored. This study identifies a number of strategies that enrich running events and can contribute to the sustainability of off-peak destinations. Additionally, the concept of synergy is identified and explored, emphasizing the importance of local engagement, participant encouragement, and community collaborations. These findings provide a comprehensive understanding of how these factors can influence the sustainability of off-peak destinations. To further validate and extend these findings, the second part of this study performs a quantitative analysis using PLS-SEM, involving eighty local authorities in Greece. The results highlight the mediating role of small-scale event enrichment strategies on the relationship between synergy and destination sustainability. This multifaceted approach indicates the dynamics of sustainable tourism, by examining the case of small-scale running events in the off-peak season. The impact of this balanced approach on the broader achievement of relevant SDGs is also supported. The implications of this research, in terms of its strategic and stakeholder orientation for tourism professionals and government agencies, are also discussed.

AI-Generated Virtual Hosts as a Cost-Effective Solution for Small-Scale Event Hosting

The rise of artificial intelligence (AI) has transformed various industries, including event hosting, where AI-generated virtual hosts are emerging as a cost-effective alternative to human hosts. While much research focuses on the technical aspects of these virtual hosts or their application in large-scale events like news broadcasting, there has been little exploration in the context of smaller, budget-constrained events. This study addresses that gap by presenting a practical framework for implementing AI-generated virtual hosts in small-scale events with clear and straightforward agendas. The framework is designed to be accessible to non-technical users and offers a low-cost solution for event organizers. A user study was conducted to assess the public’s acceptance of AI-generated virtual hosts, evaluating dimensions such as linguistic proficiency, emotional expression, interactivity, entertainment value, professionalism, and image. The results showed general satisfaction with the host’s linguistic proficiency and visual appeal, though interactivity and emotional expressiveness were noted as areas for improvement. These findings suggest that AI-generated virtual hosts are a viable, affordable alternative for small events, particularly those with minimal real-time interaction requirements.

“I Have the Feeling of Community Again”: The Socioeconomic Impacts of Small-Scale Events on Community Recovery

The COVID-19 pandemic had severe consequences for communities across the globe and especially in Melbourne, Australia, where residents experienced strict control measures and extended lockdowns. Using a mixed-methods approach, this study explores an initiative to facilitate community recovery by analyzing the socioeconomic impacts of small-scale events held by local government in Melbourne’s West shortly after the final lockdown lifted. Survey data were collected from 843 event attendees and 43 business operators, followed by semistructured interviews. Results show that these events generated multiple social benefits by enhancing a sense of community, (re)connecting people, improving mental health, and promoting diversity and inclusion. Economic benefits were generated directly by boosting local and visitor spending and indirectly through increasing business‐community connectedness. The study contributes to the limited empirical research on the value and role of small-scale events for community recovery and has managerial implications for sustainable destination development, recovery, and regeneration strategies.

Coronal Heating and Solar Wind Generation by Flux Cancellation Reconnection

In this paper, we propose that flux cancellation on small granular scales (≲1000 km) ubiquitously drives reconnection at a multitude of sites in the low solar atmosphere, contributing to chromospheric/coronal heating and the generation of the solar wind. We analyze the energy conversion in these small-scale flux cancellation events using both analytical models and three-dimensional, resistive magnetohydrodynamic (MHD) simulations. The analytical models—in combination with the latest estimates of flux cancellation rates—allow us to estimate the energy release rates due to cancellation events, which are found to be on the order 106–107 erg cm−2 s−1, sufficient to heat the chromosphere and corona of the quiet Sun and active regions, and to power the solar wind. The MHD simulations confirm the conversion of energy in reconnecting current sheets, in a geometry representing a small-scale bipole being advected toward an intergranular lane. A ribbon-like jet of heated plasma that is accelerated upward could also escape the Sun as the solar wind in an open-field configuration. We conclude that through two phases of atmospheric energy release—precancellation and cancellation—the cancellation of photospheric magnetic flux fragments and the associated magnetic reconnection may provide a substantial energy and mass flux contribution to coronal heating and solar wind generation.

Discovering the relationships between event identity, satisfaction, image, WoM, and re-participation intention

Although small-scale dance events are popular as a postmodern socialization tool for modern people, little is known about participants’ behavioral intentions in active small-scale dance events. This research examined the hierarchical relationship between event image, event satisfaction, event identity, and behavioral intentions, including re-participation intention and positive word-of-mouth (WoM) behavior, in a repeated small-scale dance event. A total of 412 participants of the Eskisehir Dance Festival (EDF), a repeated small-scale dance event, were reached by the convenience sampling method. Research data were analyzed using structural equation modeling (SEM). First, the model’s compatibility with the data was evaluated by applying confirmatory factor analysis to the model, which includes all research structures. AVE, Cronbach alpha, and CR values were analyzed for all constructs. The conceptual model of the research was analyzed using the AMOS v22. Event image is an important predictor of both event satisfaction (β =0.88; p <0.01) and event identity (β =0.46; p <0.01). In addition, event satisfaction significantly impacted event identity (β =0.76; p <0.01). Event identity is the predictor of re-participation intention (β =0.24; p <0.01) and positive WoM behavior (β =0.88; p <0.01). Finally, WoM behavior positively affected reparticipation intention (β =0.88; p <0,01). Research results made significant empirical contributions to the literature on repeated small-scale dance events. In addition, based on the research results, suggestions were presented to managers of small-scale dance events that they could use in their marketing strategies.

High-productivity, field-relevant assessment of relative fracture resistance for hard materials – The ball mill edge chipping test (BMECT)

Abrasion-resistant materials for rock-facing applications typically display low fracture toughness. For materials selection, available fracture data are limited, due to the cost of testing. To address this shortage, a new type of fracture test, denoted the ball mill edge chipping test (BMECT), has been designed. The device is derived from the ball mill abrasion test (BMAT) [37]. It uses simple block or ball specimens with machined edges. Specimens of multiple materials are tested simultaneously. Collisions promote multiple small-scale fracture events at the exposed edges, causing progressive volume loss. The reciprocal of volume loss indicates relative fracture resistance.This paper analyses the BMECT’s relevance to service, and explores its capacity to generate data at low cost. Several data sets are presented, illustrating its application to investigate factors affecting fracture resistance among common abrasion-resistant materials. The results demonstrate multiple advantages over traditional fracture tests — including low cost, high sensitivity to differentiate between materials, and close replication of in-service damage modes. It represents a fundamentally new approach to fracture resistance assessment. Whereas traditional tests are regarded as deterministic, the BMECT is stochastic, providing potential for superior statistical data quality.

Sport tourism and regional economic development

The main aim of this systematic review is to analyse the most recent literature regarding the relationship between sports tourism and its economic impact on a specific region. This research employed a systematic literature review methodology following PRISMA guidelines. A total of 64 relevant articles were identified through comprehensive searches across databases, resulting in the selection of 14 articles that met the established inclusion criteria for the study. The studies were analysed and synthesized to identify the key economic benefits and challenges of hosting sporting events. The review identified that sports tourism positively impacts regions by attracting tourists, creating job opportunities, and generating revenue for local businesses. Both small-scale and major sports events can potentially contribute to regional economic development. However, proper planning and management are essential to ensure that the benefits are maximized and that any negative impacts are minimized. There is need for further research to identify best practices for maximizing the economic benefits of sport tourism and to explore its potential for sustainable economic development.

Поэтика повседневности в творчестве С. Довлатова

The aim of the study is to identify the originality of everyday life representation, i.e., the mechanisms of reflection of everyday realities, in the creative work of S. Dovlatov based on the material of his novellas “The Compromise” (1981), “The Zone” (1982) and “Pushkin Hills” (1983), the collection “The Suitcase” (1986). The scientific originality of the paper lies in interpreting the prose writer’s works through the lens of everyday life. The results show that repeatability, closeness of space and the turn to the sphere of private life of ordinary characters represent the main features of everyday life in the analyzed works. Everyday life requires a recognizable background created by repetitive thoughts, descriptions, images in S. Dovlatov’s works, however, the routine in his writings is not monotonous, which destroys the idea of traditional everyday life as something uniform. The author highlights separate, small-scale events that are sufficient to recreate a complete picture in simple language, using similes, metaphors, euphemisms, often interspersing his works with dialogues and jokes, conveying emphasis and dyslalia. The conversational style used by S. Dovlatov to create the speech characteristics of his characters demonstrates its inherent discreteness, unfinished thoughts, incomplete syntactic constructions and brevity of utterance.

Spatiotemporal links between meteorological and agricultural droughts impacted by tropical cyclones in China

Both droughts and tropical cyclones (TCs) are among the world's most widespread natural disasters. This paper is concentrated on the effects of TCs on the links between meteorological droughts (MDs) and agricultural droughts (ADs). Specifically, changes in characteristics of drought events and variations in propagation features of matched MD and AD event pairs are quantified by using the renowned three-dimensional connected components algorithm; both alleviation and exacerbation effects of TCs are evaluated; and the Spearman's correlation is employed to identify potential contributors to exacerbated droughts after TCs. The results show that TCs exhibit more pronounced and widespread alleviation effects on MD events compared to AD events. >98 % of small-scale drought events are terminated by TCs, leading to 65 % reduction in the total area of MD events smaller than 50,000 km2 and 32 % reduction in AD events of the same scale. In the meantime, TCs can reshape the spatiotemporal links between MDs and ADs by reducing the overall propagation rate from 77 % to 40 % and ameliorating the characteristics of drought event pairs with higher propagation efficiency, by >40 %. After TCs, over 55 % of drought exacerbations in TC-affected regions occur first in the vicinity of the residual large-scale AD events. This occurrence is partially associated with the reduction in moisture exports from these residual droughts downwind to the interior of TC-affected regions, a process potentially facilitated by the TC-induced temperature cooling. The in-depth evaluation of this paper presents useful information for better drought preparation and mitigation under TCs.

Rural Art Festivals and Creative Social Entrepreneurship

This article examines how creativity-based social entrepreneurship and entrepreneurial networks in the context of small-scale rural art festivals can advance social and regional revitalization goals in peripheral island communities. This qualitative- and action-based research explores the effects of artistic activities on rural revitalization through the analysis of four small-scale rural events: a traditional matsuri (festival), and three contemporary art, music, and film festivals. The adaptability and diversity of the festivals’ entrepreneurial networks are investigated in greater depth by combining the literatures on rural revitalization, social entrepreneurship, bricolage, and resourcefulness with the embedded and relational aspects of creative entrepreneurial networks. The study also analyzes the complex relationship between the individual actions of creative festival entrepreneurs and the socially engaged creative networks that facilitate population retention and resource exchanges in a community, and therefore rural revitalization.

Exploring the genetic landscape of nitrogen uptake in durum wheat: genome-wide characterization and expression profiling of NPF and NRT2 gene families.

Nitrate uptake by plants primarily relies on two gene families: Nitrate transporter 1/peptide transporter (NPF) and Nitrate transporter 2 (NRT2). Here, we extensively characterized the NPF and NRT2 families in the durum wheat genome, revealing 211 NPF and 20 NRT2 genes. The two families share many Cis Regulatory Elements (CREs) and Transcription Factor binding sites, highlighting a partially overlapping regulatory system and suggesting a coordinated response for nitrate transport and utilization. Analyzing RNA-seq data from 9 tissues and 20 cultivars, we explored expression profiles and co-expression relationships of both gene families. We observed a strong correlation between nucleotide variation and gene expression within the NRT2 gene family, implicating a shared selection mechanism operating on both coding and regulatory regions. Furthermore, NPF genes showed highly tissue-specific expression profiles, while NRT2s were mainly divided in two co-expression modules, one expressed in roots (NAR2/NRT3 dependent) and the other induced in anthers and/ovaries during maturation. Our evidences confirmed that the majority of these genes were retained after small-scale duplication events, suggesting a neo- or sub-functionalization of many NPFs and NRT2s. Altogether, these findings indicate that the expansion of these gene families in durum wheat could provide valuable genetic variability useful to identify NUE-related and candidate genes for future breeding programs in the context of low-impact and sustainable agriculture.

High-quality maple genome reveals duplication-facilitated leaf color diversity

Acer truncatum is a horticultural tree species with individuals that display either yellow or red leaves in autumn, giving it high ornamental and economic value. 'Lihong' of A. truncatum is an excellent cultivar due to its characteristic of having autumn leaves that turn a bright and beautiful shade of red, while its closely related cultivar 'Bunge' does not. However, the molecular mechanism underlying the color change in the cultivar 'Lihong' is still unclear. Here, we assembled a high-quality genome sequence of Acer truncatum 'Lihong' (genome size = 688 Mb, scaffold N50 = 9.14 Mb) with 28,438 protein-coding genes predicted. Through comparative genomic analysis, we found that 'Lihong' had experienced more tandem duplication events although it’s a high degree of collinearity with 'Bunge'. Especially, the expansion of key enzymes in the anthocyanin synthesis pathway was significantly uneven between the two varieties, with 'Lihong' genome containing a significantly higher number of tandem/dispersed duplication key genes. Further transcriptomic, metabolomic, and molecular functional analyses demonstrated that several UFGT genes, mainly resulting from tandem/dispersed duplication, followed by the promoter sequence variation, may contribute greatly to the leaf color phenotype, which provides new insights into the mechanism of divergent anthocyanin accumulation process in the 'Lihong' and 'Bunge' with yellow leaves in autumn. Further, constitutive expression of two UFGT genes, which showed higher expression in 'Lihong', elevated the anthocyanin content. We proposed that the small-scale duplication events could contribute to phenotype innovation.

Evolution of the Spider Homeobox Gene Repertoire by Tandem and Whole Genome Duplication.

Gene duplication generates new genetic material that can contribute to the evolution of gene regulatory networks and phenotypes. Duplicated genes can undergo subfunctionalization to partition ancestral functions and/or neofunctionalization to assume a new function. We previously found there had been a whole genome duplication (WGD) in an ancestor of arachnopulmonates, the lineage including spiders and scorpions but excluding other arachnids like mites, ticks, and harvestmen. This WGD was evidenced by many duplicated homeobox genes, including two Hox clusters, in spiders. However, it was unclear which homeobox paralogues originated by WGD versus smaller-scale events such as tandem duplications. Understanding this is a key to determining the contribution of the WGD to arachnopulmonate genome evolution. Here we characterized the distribution of duplicated homeobox genes across eight chromosome-level spider genomes. We found that most duplicated homeobox genes in spiders are consistent with an origin by WGD. We also found two copies of conserved homeobox gene clusters, including the Hox, NK, HRO, Irx, and SINE clusters, in all eight species. Consistently, we observed one copy of each cluster was degenerated in terms of gene content and organization while the other remained more intact. Focussing on the NK cluster, we found evidence for regulatory subfunctionalization between the duplicated NK genes in the spider Parasteatoda tepidariorum compared to their single-copy orthologues in the harvestman Phalangium opilio. Our study provides new insights into the relative contributions of multiple modes of duplication to the homeobox gene repertoire during the evolution of spiders and the function of NK genes.

Solar Atmospheric Heating Due to Small-scale Events in an Emerging Flux Region

We investigate the thermal, kinematic, and magnetic structure of small-scale heating events in an emerging flux region (EFR). We use high-resolution multiline observations (including Ca ii 8542 Å, Ca ii K, and the Fe i 6301 Å line pair) of an EFR located close to the disk center from the CRISP and CHROMIS instruments at the Swedish 1 m Solar Telescope. We perform non-LTE inversions of multiple spectral lines to infer the temperature, velocity, and magnetic field structure of the heating events. Additionally, we use the data-driven Coronal Global Evolutionary Model to simulate the evolution of the 3D magnetic field configuration above the events and understand their dynamics. Furthermore, we analyze the differential emission measure to gain insights into the heating of the coronal plasma in the EFR. Our analysis reveals the presence of numerous small-scale heating events in the EFR, primarily located at polarity inversion lines of bipolar structures. These events not only heat the lower atmosphere but also significantly heat the corona. The data-driven simulations, along with the observed enhancement of currents and Poynting flux, suggest that magnetic reconnection in the lower atmosphere is likely responsible for the observed heating at these sites.

Neo-functionalization in Saccharomyces cerevisiae: a novel Nrg1-Rtg3 chimeric transcriptional modulator is essential to maintain mitochondrial DNA integrity.

In Saccharomyces cerevisiae, the transcriptional repressor Nrg1 (Negative Regulator of Glucose-repressed genes) and the β-Zip transcription factor Rtg3 (ReTroGrade regulation) mediate glucose repression and signalling from the mitochondria to the nucleus, respectively. Here, we show a novel function of these two proteins, in which alanine promotes the formation of a chimeric Nrg1/Rtg3 regulator that represses the ALT2 gene (encoding an alanine transaminase paralog of unknown function). An NRG1/NRG2 paralogous pair, resulting from a post-wide genome small-scale duplication event, is present in the Saccharomyces genus. Neo-functionalization of only one paralog resulted in the ability of Nrg1 to interact with Rtg3. Both nrg1Δ and rtg3Δ single mutant strains were unable to use ethanol and showed a typical petite (small) phenotype on glucose. Neither of the wild-type genes complemented the petite phenotype, suggesting irreversible mitochondrial DNA damage in these mutants. Neither nrg1Δ nor rtg3Δ mutant strains expressed genes encoded by any of the five polycistronic units transcribed from mitochondrial DNA in S. cerevisiae. This, and the direct measurement of the mitochondrial DNA gene complement, confirmed that irreversible damage of the mitochondrial DNA occurred in both mutant strains, which is consistent with the essential role of the chimeric Nrg1/Rtg3 regulator in mitochondrial DNA maintenance.

Kelvin–Helmholtz Instability “Tube” and “Knot” Dynamics. Part II: KHI T&K Dynamics in a Multiscale Gravity Wave Direct Numerical Simulation

Abstract A companion paper by Fritts et al. reviews evidence for Kelvin–Helmholtz instability (KHI) “tube” and “knot” (T&K) dynamics that appear to be widespread throughout the atmosphere. Here we describe the results of an idealized direct numerical simulation of multiscale gravity wave dynamics that reveals multiple larger- and smaller-scale KHI T&K events. The results enable assessments of the environments in which these dynamics arise and their competition with concurrent gravity wave breaking in driving turbulence and energy dissipation. A larger-scale event is diagnosed in detail and reveals diverse and intense T&K dynamics driving more intense turbulence than occurs due to gravity wave breaking in the same environment. Smaller-scale events reveal that KHI T&K dynamics readily extend to weaker, smaller-scale, and increasingly viscous shear flows. Our results suggest that KHI T&K dynamics should be widespread, perhaps ubiquitous, wherever superposed gravity waves induce intensifying shear layers, because such layers are virtually always present. A second companion paper demonstrates that KHI T&K dynamics exhibit elevated turbulence generation and energy dissipation rates extending to smaller Reynolds numbers for relevant KHI scales wherever they arise. These dynamics are suggested to be significant sources of turbulence and mixing throughout the atmosphere that are currently ignored or underrepresented in turbulence parameterizations in regional and global models. Significance Statement Atmospheric observations reveal that Kelvin–Helmholtz instabilities (KHI) often exhibit complex interactions described as “tube” and “knot” (T&K) dynamics in the presence of larger-scale gravity waves (GWs). These dynamics may prove to make significant contributions to energy dissipation and mixing that are not presently accounted for in large-scale modeling and weather prediction. We explore here the occurrence of KHI T&K dynamics in an idealized model that describes their behavior and character arising at larger and smaller scales due to superposed, large-amplitude GWs. The results reveal that KHI T&K dynamics arise at larger and smaller scales, and that their turbulence intensities can be comparable to those of the GWs.

Ethno-Event Attractiveness of the Region: Analysis and Assessment

Introduction. One of the tools for positioning the territory and a way to create a positive image is to demonstrate its unique ethnic heritage. Mordovia, having rich experience in organizing mega events, is currently focused on holding a large number of small-scale events. The purpose of this article is to identify the attitude of the population to the ethno-folklore holidays held and to assess the level of interest shown in them in the context of the problems of promoting the image of the region. Materials and Methods. The information basis of the study was the results obtained using a combination of methods: a sociological survey (of the population and the target group) and an analysis of interactive documents (statistics of queries in the Yandex search engine by keywords). The data of the online survey allowed us to determine the attitude of the population to the studied portfolio of eventful activities. Comparing the intensity of search queries with the situational context made it possible to record and evaluate the interest shown in ethnic holidays. Results. According to a sociological survey, the idea of promoting the region through ethno-cultural events enjoys support among the population. Employees of cultural institutions attach significant importance to them; the population gives priority to sports competitions and theater festivals. For respondents who perceive the region positively, ethnic and folklore holidays are of greater value. Comparison of these search queries with the thematic event context made it possible to reveal the stability of interest in ethno-cultural events held in the republic. It has been established that during the holidays the number of queries of a reference nature (naming and location) increases significantly, but there are no search queries about entertainment, ritual and gaming components of events that form ethnic specificity. Discussion and Conclusion. The results obtained allow us to conclude that the ethnic marking of small-scale events is an effective way to attract attention and a successful strategy for developing the external and internal attractiveness of the region. The results of the study are of practical importance for specialists involved in the technologies of positioning and promoting the brand of the region.

Formation and Hazard Analysis of Landslide Damming Based on Multi-Source Remote Sensing Data

Remote sensing plays an increasingly important role in the investigation of natural hazards, not only by obtaining specific data related to hazards, but also by realizing targeted research by combining with other data and/or technologies. Small-scale landslide hazard chain events occur frequently in mountainous areas with fragile geological environments and have strong destructive effects, yet have been somewhat understudied. This paper analyzes the Zhoujiaba (ZJB) landslide hazard chain that occurred in Longnan City on 18 August 2020. On the basis of the comprehensive application of multi-source remote sensing data, combined with time-series InSAR technology, electrical resistivity tomography (ERT), and numerical simulations, we studied the formation mechanism, damming characteristics, and potential outburst scenarios of this event. Our research suggests that geological structure and strong natural weathering are the preconditions for landslide development, which is eventually induced by extreme rainfall. Specific topographic conditions determine the rapid sliding and accumulation of landslide materials, and ultimately result in river damming. Our simulation results showed that a flood, rather than a debris flow, will be the result of dam outburst. When the simulated upstream inflow is 1.5 times that when the landslide occurred, 68% of the downstream village area will be flooded. The artificial spillway can effectively reduce the scale of the potential outburst flood, but there remains a risk of dam failure owing to the shallow depth. Our study of the hazard chain of a small-scale landslide using a combination of methods will provide a valuable reference for the analysis and treatment of similar hazard chains.
