M 6.0 - 90 km ESE of Sarangani, Philippines

Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=15 Dip=80 Slip=90 NP2:Strike=195 Dip=10 Slip=90 Principal Axes: (T) Plg=55 Azm=285 (P) Plg=35 Azm=105 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is not determined. RADIATED ENERGY No. of sta: 7 Focal mech.
