IRIS PASSCAL data contains seismic event recordings from a temporary network deployed across the New Madrid Zone. The University of Wisconsin-Madison research group led by Professor R.P. Meyer collected this data using arrays of up to twelve 3-component seismographs. Data collection occurred during winter and summer months from 1991 through 1993.
Use Cases
- Analyze seismic event waveforms from 3-component seismographs to locate earthquakes.
- Study temporal patterns of seismicity in the New Madrid Zone across seasonal deployments from 1991-1993.
- Model subsurface crustal structure using arrival times and waveforms recorded by the temporary array.
Strengths
- Data collected over a multi-year period from 1991 to 1993.
- Deployed up to twelve 3-component seismograph stations per array.
Limitations
- Data is historic, with the last update recorded in March 1993.
- Specific row count, file size, and column details are unknown.
