TERRAscope Data: Broadband Seismic Network Recordings from Southern California

Southern California TERRAscope is a wide dynamic range, broadband seismographic network funded by the L.K. Whittier and ARCO Foundations. Data is recorded in both continuous and event-triggered modes, with continuous data archived at the IRIS Data Management Center and triggered data archived at the Southern California Earthquake Center Data Center. The network stations are included as a subnetwork of the global seismographic network and the U.S. National Seismic Network.

Use Cases

• Analyze earthquake source mechanisms based on the described earthquake mechanisms data.
• Study seismic wave characteristics using the broadband (10 Hz to DC) recordings.
• Model regional seismic activity patterns based on data from the Southern California TERRAscope station network.
• Compare continuous versus event-triggered seismic data recording modes.

Strengths

• Data is recorded by a wide dynamic range, broadband (10 Hz to DC) seismographic network.
• Network stations are included as a subnetwork of the global IRIS network and the U.S. National Seismic Network.
• Data is recorded in both continuous and event-triggered modes, providing flexibility for different research needs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
