Rupture directivity analysis data of hydraulic fracturing-induced seismic events in a shal

The British Geological Survey (BGS) repository contains raw waveforms and rupture directivity analysis for seven hydraulic fracturing-induced seismic events. The passive seismic dataset was collected near Fox Creek, Alberta, Canada, between October and November 2016, during a stimulation that induced shallow earthquakes of magnitudes up to 3.2. The analysis, led by Dr. James Verdon and Dr. Germán Rodríguez at the University of Bristol, uses the Empirical Green's Functions method to determine rupture propagation direction.

Use Cases

• Modeling earthquake rupture directivity based on apparent source time functions and station rupture times
• Analyzing interactions between injection-induced pressure and earthquake nucleation based on rupture propagation direction
• Developing induced seismicity hazard management strategies using directivity measurements
• Time-series analysis of raw seismic waveforms from shallow, induced events

Strengths

• Includes raw waveforms and derived rupture directivity analysis for seven specific seismic events
• Data is consolidated with a detailed description and a provided Matlab script for import and visualization
• Events are documented with specific parameters: magnitudes up to 3.2 and depths less than 5 km

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic and temporal bias inherent to a single field site and a two-month collection period in 2016
