Abstract
The World Organization of Volcano Observatories (WOVO), with major support from the Earth Observatory of Singapore, is developing a web-accessible database of seismic, geodetic, gas, hydrologic, and other unrest from volcanoes around the world. This database, WOVOdat, is intended for reference during volcanic crises, comparative studies, basic research on pre-eruption processes, teaching, and outreach. Data are already processed to have physical meaning, e.g. earthquake hypocenters rather than voltages or arrival times, and are historical rather than real-time, ranging in age from a few days to several decades. Data from >900 episodes of unrest covering >75 volcanoes are already accessible. Users can visualize and compare changes from one episode of unrest or from one volcano to the next. As the database grows more complete, users will be able to analyze patterns of unrest in the same way that epidemiologists study the spatial and temporal patterns and associations among diseases. WOVOdat was opened for station and data visualization in August 2013, and now includes utilities for data downloads and Boolean searches. Many more data sets are being added, as well as utilities interfacing to new applications, e.g., the construction of event trees. For more details, please see www.wovodat.org.
Highlights
Volcanoes exhibit a complex suite of geophysical, geochemical, geologic, and hydrologic changes as magma ascends and prepares to erupt
WOVOdat was first opened to the public during the 2013 IAVCEI meeting in Kagoshima (Japan)
The standalone package uses the WOVOdat database schema and data formats for daily, in-house volcano monitoring and in-house archiving, which can feed seamlessly into WOVOdat when the data are made publicly available. This will help WOVOdat to have sustainable data population, via automated data uploads to the WOVOdat main server when the data are ready to share publicly
Summary
Volcanoes exhibit a complex suite of geophysical, geochemical, geologic, and hydrologic changes (unrest) as magma ascends and prepares to erupt. C.G. Newhall et al / Journal of Volcanology and Geothermal Research 345 (2017) 184–199 patterns, to find correlation within multi-parameter precursory datasets, or to test hypotheses about unrest at a large number of volcanoes. Newhall et al / Journal of Volcanology and Geothermal Research 345 (2017) 184–199 patterns, to find correlation within multi-parameter precursory datasets, or to test hypotheses about unrest at a large number of volcanoes This fragmented state of affairs utterly fails to take advantage of the intellectual power of worldwide observatory experience and of galloping information technologies. To make volcano monitoring data more readily accessible, and to enable searching and comparisons of those data, WOVO is developing WOVOdat, a web-accessible database of seismic, geodetic, gas, hydrologic, and other unrest from volcanoes around the world. WOVOdat was first opened to the public during the 2013 IAVCEI meeting in Kagoshima (Japan)
