- Ground-motion model is:
where a is in cm∕s2, a1 = 0.606, a2 = 0.00459, a3 = -2.136, a4 = 0.334, a5 = 0.653, a6 = 1.730, ϕ = 0.251
(intra-event), τ = 0.192 (inter-event) and σ = 0.317 (total).
- Select K-Net and KiK-Net data within geographical region 137–142E and 34N–38N with M > 5 and focal
depths 200km from 09/1996 to 07/2006. Remove inadequate records, e.g. those with small amplitudes.
- h is central depth of rupture plane.
- Data from 186 stations.
