Bulk Processing of USArray Data in Search of Dynamic Earthquake Triggering
Aaron A. Velasco: University of Texas at El Paso, Deborah L. Kilb: Scripps Institution of Oceanography, Kristine L. Pankow: University of Utah
We systematically search for dynamically triggered events from the USArray TA stations (triangles) for two teleseismic megatrust events (Japan M=9.0 2011 and Chile M=8.8 2010) and two large regional events (Baja California M=7.2 2010 and Wells Nevada M=6.0 2008). We optimize detectors to identify local and regional triggered events. These events provide a range of amplitudes and orientations (blue circles/lines), and we are processing data for all M>7 global earthquakes since 2010.
