- Ground-motion model is:
where Y is in cm∕s2, a1 = 0.595, b = 0.00395, c0 = 0.03, d = 0.0065, σintra = 0.129, σinter = 0.110 and
σtotal = 0.169.
- Data from stations in site classes I, II and III, for which derive correction factors w.r.t. overall model.
- Also derive models using data from 136 subduction earthquakes (5882 records).
- Also present models using focal depth and short period level of acceleration source spectrum as additional
- Find that including short period level of acceleration source spectrum significantly reduces inter-event σ.
