Tara Nye's data package includes 112 simulated kinematic earthquake ruptures and associated waveforms for the Cascadia subduction zone, ranging in magnitude from M6.6 to M9.4. The waveforms were generated for 191 stations onshore and offshore Vancouver Island, Washington, and Oregon. This dataset was created to supplement the lack of observed regional earthquakes for earthquake early warning testing.
Use Cases
- Testing earthquake early warning algorithms based on simulated displacement and acceleration waveforms.
- Analyzing rupture characteristics and slip distribution for subduction zone earthquakes based on the provided rupture files.
- Benchmarking ground motion prediction models using the synthetic waveforms generated for a network of GNSS and seismic stations.
- Studying the potential impact of large Cascadia earthquakes on major cities like Vancouver, Seattle, and Portland based on the simulated strong shaking.
Strengths
- Contains 112 simulated earthquake ruptures, providing a range of scenarios from M6.6 to M9.4.
- Waveforms are provided for 191 specific station locations, including 29 collocated GNSS/seismic stations and 5 ocean bottom seismometers.
- Includes both displacement (2 Hz) and acceleration (100 Hz) time series with realistic noise added.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is simulated using a 1D semistochastic model, which may not capture all complexities of real earthquake physics.
- Row count is unknown, which may limit suitability assessment.
