WOVO IAVCEI
What do we want to know to feel safe around volcanoes :
• What could happen?
• When & for how long?
• Do I have to leave, and, when can I come back?
• Could I be warned too late, not at all, falsely?
This is what we need to know to feel safe around volcanoes :
• Scientific understanding of processes, symptomatic pattern recognition (monitoring);• epidemiological forecasting, activity characteristics, hazard assessment;• Mitigation of human and infrastructure impact of volcanic activity, decision-making structure, relief logistics;• Reliability and accountability uncertainty concept (accuracy, forecast precision)
Volcano observatory rationale & mission: the business needs
5VOG 2007 Denver Schwandner et al.: WOVOdat
WOVO IAVCEI
Monitoring Analysis Predictions
• early symptoms monitoring assessment and prediction; possibly forecast
• epidemiological databases (multidisciplinary ) past diagnoses, historic case studies
• patient file with individual history
VDAP* Volcano response to the Mount Pinatubo crisis in the Philippines. USGS and PHIVOLCS personnel install a seismic station near Mount Pinatubo six weeks before the devastating eruptions. Installation of a monitoring network is a team effort. -- USGS
* (U.S. Internat’l Volcano Disaster Assistance Program, established after the 1984-85 Navadop del Ruiz, Colombia eruptions, lahars)
How to forecast a springtime cold and its eruptions
appropriate predictions available in medical science, not for volcanoes
- time & cost saving - efficiency & accuracy live saving

1 from WOVO to WOVOdat
WOVO: ca. 70 volcano observatories globally !(WOVOdat < IAVCEI Commission< IUGG Association)
7VOG 2007 Denver Schwandner et al.: WOVOdat
WOVO IAVCEI
Data sources: volcano observatory data flow
“Volcano observatories acquire multidisciplinary data”
Data types (examples):
• imagery (satellite, ground, IR, radar)• sound (seismic waves)• deformation (tilt, uplift, etc.)• narratives (visual observations, e.g. tree kill)• gas chemistry, hydrology • geology (eruptive history & styles)
Result: Data jungle of multiple formats, frequency, density, resolution…
Volcano monitoring techniques (USGS)
8VOG 2007 Denver Schwandner et al.: WOVOdat
WOVO IAVCEI
Data sources: volcano observatory data management
“Volcano observatories combine interdisciplinary expert knowledge “
Multidisciplinary data sets – differing in:
• Format• Frequency• Density• Resolution• Terminology • Scale
Result: “Data Stretching ” in times of crisis USGS Hawaiian Volcano Observatory

Users (observatories, decision-makers)
WOVOdat: data of volcanic unrest
• geo-relational database
• user-friendly
• Internet-based
• global
• query & analysis tools

2 Use, function and coverage of WOVOdat
11VOG 2007 Denver Schwandner et al.: WOVOdat
WOVO IAVCEI
Using WOVOdat:
• Single-volcano data monitoring and analysis (symptoms): visualization on same screen
• Comparison to prior similar events (epidemiology)
• Postulation and testing of hypothesis on active process (diagnosis)
• Data dissemination, outreach
• “remote volcano disaster assistance”

Data tables: centers around the “volcano tables”
WOVOdat table groups:• Volcano• Eruption• Seismic • Deformation• Gas• Hydrology• Potential Fields• Thermal• Inferred Processes• Common/shared
• Data problems: • ownership, grace period• frequency• admin vs. data retrieval

WOVO IAVCEI
Current status:• relational database structure is finalized (WOVOdat 1.0)• pilot study is under way (NIED/Japan and INGV/Italy)• server in Japan, using MySQL• administrative structure has been built• file transfer: staging table format being defined, xml
Next steps:• API programming• adapting existing visualizations• defining first application modules to be outsourced to interested groups• define long-term funding and institutional host

WOVO IAVCEI
Content and attribute changes: The WOVOdat editorial board• point-contact domain experts (chief editor, domain chief editors)• associate editors, outsourcing of evaluations to “reviewers”• functions alike journal reviews
Formats, modules, & imports:• Technical Adisory Committee
• application modules management• philosophy: db independence of source formats AND submissions independent of db• staging table approach defines a de-facto global data format• xml based statements• statements follow a simple set of rules (hierarchical classes)
Political decisions: • Steering Committee (23 member, international)• Leadership team of 5 (Malone, Marzocchi, Newhall, Schwandner, Venezky)
