Pinon Flat Array: 270 Seismic Events from 28 Sensors, 1991

270 triggered seismic events were recorded by a 28-sensor array at Pinon Flat, with 130 earthquakes located within 450 km and 3 nuclear explosions from the Nevada Test Site. The data was collected by SCIOPS and last updated in April 1991. All stations used STS-2 or Guralp CMG-3ESP sensors, sampling at 100 sps.

Use Cases

• Analyze seismic wave propagation based on data from a 28-sensor array arranged in concentric rings.
• Compare earthquake signals with nuclear explosion signatures based on the 3 recorded nuclear events.
• Study regional seismicity based on the 130 earthquakes located within 450 km of the array.
• Develop or test seismic event detection and localization algorithms using triggered 100 sps data.

Strengths

• Contains 270 distinct seismic events, providing a substantial sample for analysis.
• Includes 130 earthquakes with known locations within a 450 km radius.
• Records 3 nuclear explosions, offering a rare comparative signal type.
• Usts a structured 28-sensor array with high-quality STS-2 or Guralp sensors.

Limitations

• Last updated 1991-04-30 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.
