Felt in the Manila area. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=167 Dip=69 Slip=11 NP2:Strike=73 Dip=80 Slip=159 Principal Axes: (T) Plg=22 Azm=28 (P) Plg=7 Azm=121 Comment: The focal mechanism is moderately well controlled and corresponds to left-lateral strike-slip faulting with a moderate reverse component. The preferred fault plane is NP1. RADIATED ENERGY No. of sta: 5 Focal mech.
