Seismic Stations

GPS Stations

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

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?
