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


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)


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)


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


WOVO IAVCEI

Users (observatories, decision-makers)

WOVOdat: data of volcanic unrest

• geo-relational database

• user-friendly

• Internet-based

• global

• query & analysis tools

• multidisciplinary

• multi-format

• open-source

2 Use, function and coverage of 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”

3 Structure of WOVOdat


WOVO IAVCEI

Venezky & Newhall 2007: WOVOdat 1.0 http://pubs.usgs.gov/of/2007/1117/

Georelational database: schema


WOVO IAVCEI


Data importation: staging table / flat files, conventions

Syntax convention: ab_cde_fgh


WOVO IAVCEI


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


Data tables: common/shared tables: junction tables

WOVOdat tables: link volcano tables to observatory tables

• Bibliography• Contacts• Permissions• Maps• Registry• …

4 Status


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



WOVOdat today


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)
