抄録

The previous calculations of static stress changes for the geodetic fault model of the 1995 Kobe earthquake in HASHIMOTO (1995) contains an error in input of parameters. We correct the figures of the distribution of calculated stress changes. The conclusions derived in HASHIMOTO (1995) are not significantly affected, but there are two major differences. (1) The largest aftershock (M 5.4) might have occurred in the zone of CFF increase for the nearly E-W trending right lateral mechanism, while it was hard to find correlation between this aftershock and CFF changes because this event is located in the region of little CFF change in the previous study. (2) The increase of CFF for the westward dipping thrusts in the Osaka plain in the previous study turns to a slight decrease by 0.04MPa.
