  1. Kilauea and Pu’u O’o

  2. Initial Activity Along East Rift1983-1986

  3. Activity Along East Rift1983-2007

  4. New Lava Lake in Pu’u O’oJuly 1, 2007

  5. Seismic Stations

  6. GPS Stations Tilt Stations

  7. In Class Exercise • Break up into groups of 4 • Choose one person to play the following roles: • GPS specialist – will analyze GPS data • Tilt specialist – will analyze Tilt data • Seismologist – will analyze RSAM data • Scientist in Charge of Hawaii Volcanoes Observatory – will read update on volcano over past weeks to months

  8. In Class Exercise • I will hand out a packet of data for each group • Separate the packet and distribute accordingly • Take a few minutes to study your data. • Describe any trends or irregularities you might see. • DO NOT ATTEMPT TO INTERPRET THE DATA!

  9. In Class Exercise • Report the data to the scientist in charge • Together, identify any trends or correlations between the data sets. • Hypothesize what may be happening

  10. RSAM Data STC short period (EHZ) and Broadband (BHZ) data for July 2007.

  11. RSAM Data STC short period (EHZ) and Broadband (BHZ) data for July 19-25, 2007.

  12. GPS Data

  13. Tilt Data

  14. Combined Deformation Data

  15. All Data – Any Hypothesis? GPS Moving North GPS Moving Vertically Tilt Rapidly Increases Increased Seismic Amplitude Increased Seismic Amplitude

  16. Other Techniques? • Are there any other techniques we can use to figure out what is going on at Pu’u O’o before the helicopter arrives to fly us out? Pu’u O’o

  17. Morning of July 21st Afternoon of July 21st July 22nd July 20th Webcam

  18. Hypothesis? • What signal would you expect from a lava lake draining? • How would the draining of a lava lake correspond to an inflation event? • Where might the lava be going? Pu’u O’o

  19. Fissure Eruption!

  20. Fissure Eruption!

  21. Revisiting The Data… Summarize as a group GPS Moving North GPS Moving Vertically Tilt Rapidly Increases Increased Seismic Amplitude Increased Seismic Amplitude
