Felt (III) at Yuzhno-Kurilsk. Felt (I JMA) at Nemuro, Hokkaido. FAULT PLANE SOLUTION: P-Waves NP1:Strike=33 Dip=76 Slip=90 NP2:Strike=213 Dip=14 Slip=90 Principal Axes: (T) Plg=59 Azm=303 (P) Plg=31 Azm=123 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2.
