Tilt Stations
• 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
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!
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
In Class Exercise
STC short period (EHZ) and Broadband (BHZ) data for July 2007.
RSAM Data
STC short period (EHZ) and Broadband (BHZ) data for July 19-25, 2007.
RSAM Data
GPS Data
Tilt Data
Combined Deformation Data
GPS Moving North
GPS Moving Vertically
Tilt Rapidly Increases
Increased Seismic Amplitude

All Data – Any Hypothesis?
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?

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?
