Highlights

  • WOVOdat is a growing, online database of worldwide volcanic unrest.
  • Users may browse, plot, and download catalogue-level (processed) data.
  • Users may compare unrest through time at single and analogous volcanoes.
  • The value of WOVOdat will depend significantly on its completeness. Please add your data!
  • WOVOdat offers basic apps for data visualization and Boolean searches. Please offer new apps!

WOVOdat organized a one week workshop on "How to Optimize the Use of Volcano Monitoring Database" at Earth Observatory of Singapore - NTU.

Participants: Centre for Volcanological and Geological Hazard Mitigation (CVGHM, Indonesia), Philippine Institute for Volcanology and Seismology (PHIVOLCS, Philippine), Rabaul Volcano Observatory (RVO, Papua New Guinea), and EOS volcano group.

Topics:

  • Brainstorming and discussion on how WOVOdat system will be used and useful during volcano crisis, for eruption forecasting.
  • Exchange experiences between volcano observatory on using WOVOdat as their monitoring database. PHIVOLCS has been developing data processing automation (SEISAN to WOVOdat, SWARM to WOVOdat, VALVE to WOVOdat), and various operational tools developed in PHIVOLCS and CVGHM localhost.
  • New tools developed by WOVOdat team: installation and operational.
  • Future development and plan of WOVOdat.
Time: 26 - 29 November 2018
Venue: BPPTKG, Yogyakarta, Indonesia - Center for Volcanology and Geological Hazard Mitigation (CVGHM)
Participants: CVGHM (Indonesia), PHIVOLCS (Philippines), RVO (Papua New Guinea), SERNAGEOMIN (Chile), IPGP (France), INGV (Italy), NIED (Japan), ERI (Japan), MVO (Montserrat), USGS (USA), EOS-NTU (Singapore)
Topics:

The most challenging task during volcanic crisis is to interpret the monitoring data, to better anticipate the evolution of the unrest that allow implementation of timely mitigation actions. The volcanologist needs to make an informed decision on what is likely to happen next. In addition to real time monitoring data, the volcanologist needs to rely on historical unrest and past eruption episodes at the same volcano. Such analysis requires a standardized and organized database of past events. However, many volcanoes have limited instrumental records of past eruptions (or none!) and thus an assessment needs to be made by comparing its activity to analogue volcanoes that may have more complete records. This requires the existence of global database, such as WOVOdat.

WOVOdat is intended to provide reference data useful during volcanic crises, for comparative studies, and basic research on pre-eruption processes.

Activities during the workshop would be: exchanging experiences between observatory staffs/participants on handling volcano monitoring data, strategize and improve on monitoring data management and past unrest data analysis to better anticipate future unrest/eruption, and hands on experiences in using WOVOdat online interface.
