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, log10 cm*km^2 units Mp: Potency magnitude, equivalent to moment magnitude (Mw) assuming a shear modulus of 36 GPa
