• 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

• 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

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?
