- Ground-motion model is:
- Use 2 site classes:
S = 0
S = 1
- Response parameter is acceleration for 5% damping. Also derives models for various nonlinear response
- Uses similar data to Joyner and Boore (1981) and Campbell (1981).
- Notes data reasonably well distributed except for lack of data for Mw > 7, rjb < 10km and small
earthquakes at long distances. Notes that model most reliable for small-to-moderate earthquakes at
moderate-to-large distances, where data is densest.
- Compares observations (grouped by magnitude ranges) and predictions against distance.
