A comprehensive geophysical investigation to assess seismic hazards in the coassesment of seismicity in the Wabash Valley
Entry ID: PASSCAL_WABASH

[ Update this Record ]

Summary
Abstract: Recent paleoseismic evidence had shown there were 5-8 magnitude
greater than 6 earthquakes in this region in the past 20,000
years. The study area has always been at the fringe of previously
operated seismic networks. A focused, short-term deployment was
designed to lower the detection threshold to determine seismicity
rates for the region for comparison with estimates derived from
paleoseismicity. The researchers hoped to relate observed seismicity to faults
mapped in the subsurface through new seismic reflection data made
available to the Illinois Basin Consortium.

Quality Recording parameters: Ten stations recorded continuously at 40 sps for
the duration of the experiment with very few gaps. These stations were
located in an areal array with an aperture of approximately 1 km. The
other ten stations ran REFTEK triggers and recorded at 250 sps.

Problems: Due to a throughput problem that was not recognized ... View entire text
