WOVOdat: (The World Organization of Volcano Observatories Database of Volcanic Unrest): post-design phase pilot application development

The World Organization of Volcano Observatories (WOVO) is developing a global database of volcanic unrest (WOVOdat), based on monitoring data of its about 70 member observatories and partner institutions. WOVOdat will be web-accessible and serve as an important reference tool for interpreting volcanic unrest and forecasting eruptions. Prior problems and delays in forecasting volcanic eruptions can be eased if contemporary symptoms of unrest can be compared with unrest at similar volcanoes for which the outcome was known. In addition, forecasting efficiency was often hampered by data disparity and access issues. This volcanic “epidemiological” tool will greatly expand ways that data can be used and exchanged. WOVOdat will enable the visualization of such disparate data in a common query and analysis environment, using open source software with superimposed custom programmed scripts and visualization tools.

A revised relational database schema (WOVOdat 1.0, Venezky & Newhall, 2007) covers sets of data that differ strongly in subject, time and spatial coverage, sampling frequency, accuracy and precision, and formats. Logical connections between all of these data sets are a challenge, and with the ongoing development of new instrumental technology on the ground, the database schema will have to be able to adapt to future modifications and additions. Data entry will be through simple web forms and on a staging table (metafile) system using a server-side script accessible to WOVOdat administrators only, and custom script for varied sources. A domain expert editorial board will provide expert guidance for the developer team.

This schema (WOVOdat 1.0) serves as the basis for a pilot project currently under way, led by partners in Japan and Italy. The server location is in Japan, and the database engine, developed in open-source MySQL, will be tested with data from NIED, INGV, and other contributors. The system architecture will include a central WOVOdat server with contributing partners (observatories, institutions). Modular client applications will provide additional tools and visualization solutions.
