Geotiffs and accompanying ASCII, .csv, and metadata that describe independent and dependent earthquake density for the INGENIOUS study area, developed at the Nevada Geodetic Laboratory at the Nevada Bureau of Mines and Geology (NBMG). Files contain: longitude, latitude, and various alpha values. The unit for the rate density for the different cases is 10-12 y-1 m-2. The ASCI and .csv contain points in WGS84. Geotiffs have been projected and resampled to a custom INGENIOUS grid in NAD83 Contiguous USA Albers, with central meridian of -117.
Dataset description (independent): Earthquake rate density derived from the ANSS catalog for M≥2 earthquakes between Jan 1, 2003 and Dec 31, 2020. This dataset is based on independent earthquakes as identified by the algorithm of Zaliapin et al. That algorithm allows for different threshold values (alpha) that set the aggressiveness of separating dependent from independent events, with lower alpha identifying fewer independent events. The algorithm to derive the rate density is described in a manuscript in review with Seismological Research Letters. We present results for three different values of number of events considered (N) and results cover the entire western U.S. (clipped to INGENIOUS study area for this compilation).
Dataset description (dependent): Earthquake rate density derived from the ANSS catalog for M≥2 earthquakes between Jan 1, 2003 and Dec 31, 2020. This dataset is based on dependent earthquakes (i.e., foreshocks and aftershocks) as identified by the algorithm of Zaliapin et al. That algorithm allows for different threshold values (alpha) that set the aggressiveness of separating dependent from independent events, with lower alpha identifying fewer independent events. The algorithm to derive the rate density is described in a manuscript in review with Seismological Research Letters. We present results for three different values of number of events considered (N) and results cover the entire western U.S. (clipped to INGENIOUS study area for this compilation).
