Integration of the NEES T-Rex Vibrator and PASSCAL Texan Recorders for Seismic Profiling of Shallow and Deep Crustal Targets

In September 2004, Stanford University and the University of Texas (UT) at Austin collected crustal reflection and refraction data with the Network for Earthquake Engineering Simulation (NEES) tri-axial (T-Rex) vibrator in two separate surveys: (1) a 40-km “crustal-scale” profile in the Black Rock Desert and Black Rock Range, NV; and (2) a 16-km “high-resolution” basin imaging profile in Surprise Valley, CA (figure 1). Both experiments were completed at the northwestern margin of the Basin and Range Province, embedded in a larger, 300-km wide-angle refraction line recorded by an Incorporated Research Institutions for Seismology (IRIS) PASSCAL transportable array (...
