Potency Magnitude Catalog for Western US Earthquakes: 1950-2024

Earthquake catalog for the western US, derived from the US Geological Survey's Comprehensive Catalog (https://earthquake.usgs.gov/earthquakes/search/) and supplemented with estimates of seismic potency and potency magnitude. The dataset is space-delimited with the following columns, listed on the header line: evid: ComCat event id time: ComCat preferred origin time (UTC) lat: ComCat preferred latitude lon: ComCat preferred longitude dep: ComCat preferred event depth mag: ComCat preferred magnitude mag_typ: ComCat preferred magnitude type logP0: Estimate of seismic potency in units of cm*km^2 (log10) Mp: Potency magnitude, equivalent to moment magnitude (Mw) assuming a shear modulus of 36 GPa in calculated moment main: Clustering designation (1 or 0) indicating whether or not the event is the mainshock within a cluster of events. Clustering is defined via the nearest-neighbor diagram method of Zaliapin and Ben-Zion (2013).
