Seismic reflection data imaging the Meadow Bank scarp in the Wabash Valley Seismic Zone, southeastern Illinois, U.S. Geological Survey data release

The U.S. Geological Survey, in collaboration with seismologists from University of Kentucky, performed a 917-meter east-west oriented shear horizontal (SH)-wave seismic-reflection survey in the Wabash Valley Seismic Zone in southeastern Illinois. The resulting profile, named ML-2, images the near-surface geology underlying the Meadow Bank scarp, a roughly 10-km long northeast-oriented topographic anomaly with 6 meters of elevation change over 100 meters where ML-2 crosses the scarp. ML-2 was acquired using a landstreamer with 24 pairs of polarity-compatible 4.5 Hz horizontal geophones at 0.76-meter channel spacing. A 50-kilogram steel roller towed behind a truck and struck with a 1.36-kilogram hammer provided SH-wave energy. This dataset contains seismic-reflection records from ML-2 in SEGY format, observer’s logs detailing survey parameters and field conditions, and station locations in Universal Transverse Mercator (UTM) coordinates.
