EFFECTS OF SURFACE SOIL AND EARTHQUAKE SOURCE RADIATION ON THE GROUND MOTION OF 1.6G ACCELERATION, OBSERVED DURING THE AUGUST 8,1993, SOUTH-WEST OFF HOKKAIDO EARTHQUAKE JAPAN.

抄録（英）：
We examined the reasons why the ground motion of 1.6g was observed at OTB from the largest aftershock of the 1993 SW-Off Hokkaido earthquake. The strongest effect was a large amplification due to shallow surface soils overlying hard rock. The amplification factor relative to rock motion was around 40 at a resonance frequency and roughly 10 for maximum amplitude in time domain. In addition, a source radiation effect was also significant. SV-waves from this event predominated in the direction to OTB. It is also plausible that the source directivity contributed to the large amplitude at OTB.
