抜粋

The observed far-field accelerograms of the mainshock are simulated by using the records of the second largest aftershock of Ms 6.9 as Green's functions in order to obtain appropriate fault models for the mainshock. The strong ground motions in the meizoseismal region of the mainshock are then estimated by using these fault models and the records of several aftershocks with a magnitude of about 5 which were observed at temporary stations in the damaged area. The results indicate that large horizontal acceleration responses over 1000 cm/sec2 and vertical acceleration responses over 2000 cm/sec2 acted on the structures with natural periods shorter than 0.1 sec in the wide meizoseismal region having a length of 90 km. -from Authors
