Sand Box: Search/Plot Faults in Western US to Get Details The USGS 2023 Seismicity Model for the western United States is built from an exceptionally large dataset: 553,115 earthquake scenarios. These scenarios represent the expected seismic behavior of 1,016 regional crustal faults, referred to in the USGS report as parent faults (see Figure 1). Many…

Sand Box: Search/Plot Earthquake Scenarios to Get Details and Conduct Ground Motion Analysis The 2023 USGS seismicity model for faults in the western United States presents the regional seismicity through many earthquake scenarios that rupture multiple fault sections. This reflects decades of observations that large crustal earthquakes often rupture sections of different neighboring faults. The…
