Gregg Brenn’s Summer 2013 Keck Fellowship Summary

I participated in a Keck Geology Consortium project to the Nicoya Peninsula of Costa Rica, where I was characterizing the aftershock seismicity above the rupture zone of the September 5, 2012 Mw= 7.6 Nicoya Earthquake.  The Keck group consisted of a geophysics team and a geomorphology team, and I was part of the the 4-student geophysics team, along with Costa Rican seismologist Dr. Marino Protti, in which we deployed a local, 5-station seismic array and GPS network.  Our goal was to monitor for earthquakes, and with the data collected, we will locate the epicenters and depths to understand where the earthquakes are occurring along the plate interface.  This was a great opportunity to gain experience deploying and servicing seismic stations in a tectonically active field environment, and I hope to use this data to contribute to future megathrust earthquake prediction on the Nicoya Peninsula.
