Executive Summary Earthquakes represent one of our Nation’s most significant and costly natural hazards, with estimated annual loses from earthquakes close to $15 billion in 2023. Over the past two centuries, 37 U.S. States have experienced an earthquake exceeding a magnitude of 5, and 50 percent of States have a significant potential for future damaging shaking; these statistics speak to the need

Caltech/USGS Southern California Seismic Network (SCSN) and Southern California Earthquake Data Center (SCEDC): Data availability for the 2019 Ridgecrest sequence
The 2019 M6.4 and M7.1 Ridgecrest earthquake sequence occurred in the eastern California shear
zone (ECSZ). The mainshock ruptured the Little Lake fault zone and aftershocks extended from
the Garlock fault in the south, to the southern end of the 1872 M7.5 Owens Valley earthquake
rupture in the north. We present data from the Southern California Seismic Network (SCSN) and
partner seismic networks

The Station Information System (SIS): A centralized seismic station repository for populating, managing, and distributing metadata
Creating, maintaining, and archiving accurate station metadata is critical for successful seismic network operations, data discovery, and research. The Station Information System (SIS) is a centralized repository of seismic station equipment inventory, instrument response, and site information of stations operated by regional seismic networks (RSNs) of the Advanced National Seismic System (ANSS; F
