M 6.9 - 150 km SE of Tondano, Indonesia

Felt (IV) at Manado and Ternate, Indonesia. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=168 Dip=83 Slip=90 NP2:Strike=348 Dip=7 Slip=90 Principal Axes: (T) Plg=52 Azm=78 (P) Plg=38 Azm=258 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2. RADIATED ENERGY No. of sta: 10 Focal mech.
