Canterbury Time-dependent Seismic Hazard Model: Fault Source Model
Database
This model estimates the amount of earthquake shaking in the Canterbury region for the next 50 years. Here, you can download the earthquake rate model and the combined forecast for 50 years here.
Overview
The fault source model is based on the model explained in Gerstenberger et al. (2014, see citation below).
The format of the fault source file:
- Rows 1-3: Ignore
- Row 4: Abbreviated fault source name and slip type (rv=reverse, ss=strike-slip, nn=normal, nv=normal-volcanic, if=subduction interface, sr=strike-slip and reverse, sn=strike slip and normal, ns=(etc)
- Row 5: Number of digital straight-line sections (n) making up the source
- Row 6: Dip, dip direction, depth to base, depth to top
- Row 7: Endpoints of fault source in degrees and mins, characteristic Mw, and mean/preferred recurrence interval
- Rows 8 to (8+n-1): Endpoints of digital straight line sections making up fault source (one row per digital section)
- Row 8+n-1: End of fault source delimiter
Please note, these files provide the expected number of events, and do not provide the expected shaking (hazard) levels.
