2017-09-23: Seismic refraction study at Kennedy Space Center

Glenn Thompson, Sarah Kruse and Charlie Breithaupt led a seismic refraction study at Kennedy Space Center.

The study had two purposes:
(1) To ascertain the seismic P, S and surface wave velocity structure in the vicinity of Space Launch Complex 40 and The Astronaut Beach House.
(2) A training exercise for students on Sarah Kruse's Geophysics course.

Two types of survey were conducted simultaneously. The first was a standard seismic refraction study with a string of 24 geophones (spaced up to 3-m apart) attached to a geode datalogger and a Windows laptop. The second was a surface-wave streamer (to capture surface waves, which are strong, the geophones do not even need to be in the ground). Sledgehammer and Betsy (shot)gun were used a source for both, with end-offsets of up to 176m.
The results obtained will help interpret seismic (and infrasound) data recorded during the explosion of the SpaceX Falcon9 rocket that occurred on 1-Sep-2016.
