Santa Cruz Mountains Dense Array: Seismic Recordings from Controlled Explosions

May 1991 data from a controlled seismic source experiment in the Santa Cruz Mountains. The dataset was collected by the SCIOPS organization using an array of 20 three-component short-period sensors at the Zayante station, recording five chemical explosions ranging from 1000 to 3000 pounds located 10 to 40 km away.

Use Cases

• Analyzing seismic wave propagation based on recordings from controlled explosions.
• Studying array response and signal coherence based on data from 20 closely spaced sensors.
• Modeling subsurface structure based on seismic signals from known source locations and strengths.
• Comparing aftershock site data based on the reuse of a station from the 1989 Loma Prieta experiment.

Strengths

• Data originates from a controlled experiment with known source parameters (5 explosions, 1000-3000 lbs).
• Recordings were made by a dense array of 20 three-component sensors with an average 15-meter spacing.
• Source locations were precisely defined, ranging from 10 to 40 km from the sensor array.

Limitations

• Last updated 1991-05 31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
