Description:

Abstract:

Description: The earthquakes that occurred in the earthquake catalog (ANSS) were put into the equation for moment release: log(Mo)= 1.5*Mw + 16.1 where Mw is the moment magnitude and Mo is the moment release in dyne-cm (Bolt, 1999) These values were added inside their respective 0.1-degree grids, logarithmically normalized and smoothed to 0.3-degree grids. The moment release map encompasses far broader regions of high values than does the earthquake count map. It is important to keep in mind that the broad character of this map is due to the smoothing of the data and may not reflect an actual broadening of moment release. Some areas of high earthquake frequency, however will display relatively higher numbers when compared with the earthquake count map. The Long Valley Caldera appears very clearly along with the Central Nevada Seismic Belt. The northern part of the Walker Lane also shows up much more clearly than in the earthquake count map. The Southern Nevada Seismic Belt is far more obvious in the moment release map than the earthquake count map. The Wasatch Front, though, is actually deaccentuated due to the low moment magnitude of earthquakes in this area.

Purpose: For geologic, mineral, or geothermal exploration
