  1. A New System for Publishing and Archiving Volcano Hazard Information Statements using the Common Alerting Protocol (CAP) Dina Y. Venezky and Seth Snedigar USGS VHT and AVO ADGGS

  2. The Volcano Hazards Program is responsible for monitoring all US volcanoes and issuing timely forecasts of volcanic hazard

  3. Volcano Hazards Program comprises 5 Volcano Observatories and other major partners

  4. LVO - Long Valley, California • Caldera formed ~760,000 ka • Most recent eruption ~250 yrs ago • > 3 M visitors / year • Several deaths this year due to CO2

  5. YVO - Yellowstone, WY • Three caldera forming eruptions (2.1 Ma,1.3 Ma, 0.64 Ma) • Most recent eruption ~ 70 ka • < 3 M visitors / year • Active hydrothermal system

  6. Currently erupting CVO - Cascades, Pacific Northwest • Monitors the Cascades • Mount St. Helens activity since 2004 • Mt. Rainier has > 1 M visitors / year and 3 M people live nearby

  7. HVO - Hawaii Currently erupting • Kilauea: erupting since 1983 • Mauna Loa: last erupted in 1984, • Increased signs of unrest since 2002 • > 1 M visitors / year

  8. Currently erupting AVO - Alaska • Monitors > 20 volcanoes • Volcano accessibility challenges • Ash is dangerous to aviation • 1989 KLM 747 lost power • Regained power after descending out of cloud • > 4 M airplane passengers / year

  9. 3 4 1 2 We monitor volcanoes remotely Received on Amchitka Earthquake Occurs on Little Sitkin Downlink in Palmer Processing and Automatic Analysis Scientific Analysis

  10. We record an event… Now what?

  11. Small remote earthquake information is logged

  12. More populated centers release daily updates One small earthquake (M=0.8) in the Long Valley caldera region since the last update on May 1. Long Valley Daily Update issued 10:57:32 AM on May 2, 2006 - Color Code GREEN

  13. Less populated areas release updates for elevated activity Augustine volcano has entered a period of repetitive explosive eruptions. • Timing of eruptive events • Hazards (example, lahar) • Height of ash cloud • Ash fall area

  14. Multiple stakeholders determine response FAA NWS Media

  15. Update frequency differs among observatories • LVO - daily • AVO - daily(elevated color code)weekly(monitored) • YVO - monthly • HVO - daily(Kilauea)weekly(Mauna Loa) • CVO - daily(MSH) • CNMI - weekly (Anatahan) As needed for new events

  16. CAP is an XML based universal format • Common Alerting Protocol (CAP) created for exchanging response information • RSS Feed • Bridges communication gap among agencies at all levels • One message disseminated over multiple warning systems

  17. CAP language created for generic disaster scenarios • Urgency - Immediate, Expected, Future, Past, Unknown • Severity - Extreme, Severe, Moderate, Minor, Unknown • Certainty - (Observed) Very Likely, Likely, Possible, Unlikely, Unknown We need to fit volcanic events into CAP language

  18. We created a customizable and flexible system • Simple form • Observatories have customized front page • Data pulled from MySQL tables using PHP • Observatory name triggers scripts on all common pages

  19. Event vocabulary developed to supplement CAP information Event: Seismicity, Deformation, Thermal, Gas Emission, Volcanic Activity Dim glow? Vog? No mention? How do you translate non standard event descriptions into standard keywords?

  20. One form multiple outputs • Inserts into archive • Sends to DMIS • Sends email • Creates RSS feed • Posts on websites

  21. Subscribe to our RSS feeds

  22. Challenges • Different volcanoes • Types • Accessibility • Densities of networks • Different audiences • Airlines (FAA / NWS) • Land developers / Skiers • Limited resources

  23. Our new system creates and archives alerts • Used by program • Refining code, use, and process • Revising websites to supplement information
