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

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? Pu’u O’o

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
