M 6.0 - 184 km ESE of Kuril’sk, Russia

Two events about 1.7 seconds apart. Depth from broadband displacement seismograms, based on second event. FAULT PLANE SOLUTION: P-Waves NP1:Strike=57 Dip=78 Slip=90 NP2:Strike=237 Dip=12 Slip=90 Principal Axes: (T) Plg=57 Azm=327 (P) Plg=33 Azm=147 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2. RADIATED ENERGY No. of sta: 15 Focal mech.
