Drone application for landslide hazard assessment on the Western Flank of Lawu Volcano, Central Java, Indonesia

Abstract

Remote sensing technology advancements have opened novel possibilities for precise and effective landslide investigation. Because both regions have rocky topography, this study will employ unmanned aerial vehicles (UAVs) or drones to examine landslide activity on the west side of Mount Lawu, namely in Nglelaka Hamlet, Segorogunung Village, Ngargoyoso District and Guyon Hamlet, Tengklik Village, Tawangmangu District. Landslides are caused by the rocks and their geological conditions. As a result, extensive monitoring is essential to ensure that mitigation activities are carried out exactly. The spatial and descriptive analysis strategy was employed in this study. Data collecting methods used included landslide censuses and field surveys. A Geographic Information System was then used to process the data. According to the research findings, the landslide in Nglelaka Hamlet was of the translational kind, but the landslide in Guyon Hamlet was of the termite type. The findings of this study helped us better understand the dynamics of landslides in diverse locations, particularly in difficult-to-reach areas, and demonstrate how beneficial UAVs can be in gathering data for disaster management and community resilience. Drones for landslide studies offer valuable information to local governments and stakeholders, allowing them to develop preventative measures and emergency response plans, lowering the impact of landslides on residents and infrastructure.
