In two earlier papers (Wallace et al., 1983, 1985), we discussed the evidence for tectonic release from underground nuclear explosions on Pahute Mesa at the Nevada Test Site (NTS) as observed in long-period body waves. It has been shown for some time that the nonisotropic component of the surface waves from most of these events could be explained by an equivalent double-couple source; namely st...

Interpretation of subsurface geology is greatly enhanced by 3-D seismic data, and this accounts for its ubiquity in today’s search for hydrocarbons. Seismic interpretation has two fundamental disciplines at its core: seismic geomorphology and seismic stratigraphy. Plan views allow the explorationist to apply principles of geomorphology, based on analogies with modern sedimentary systems, to int...

Abstract Earthquakes on strike-slip faults are preserved in the geomorphic record by offset land-forms that span a range of displacements, from small offsets created most recent earthquake (MRE) to large cumulative slip multiple prior events. An exponential decay number has been observed many faults, and leading hypothesis is climate controls rate decay. We present measurements compiled 31 stud...
