7. 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

8. 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

9. 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
