In order to find the direct evidence of motion of fore-arc sliver along the Kuril trench, we investigated the distribution of fault plane solutions along the estimated boundary of Kuril fore-arc sliver in Hokkaido. Using the P-wave polarity data as well as P- and SH-wave amplitudes, we determined the fault plane solutions of smaller events (2.0
