Some damage (VI RF) was reported in the Bislig-Butuan-Surigao area. Felt (IV RF) at Cagayan de Oro, (III RF) on Camiguin and (II RF) on Cebu. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=355 Dip=65 Slip=90 NP2:Strike=175 Dip=25 Slip=90 Principal Axes: (T) Plg=70 Azm=265 (P) Plg=20 Azm=85 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2. RADIATED ENERGY No. of sta: 7 Focal mech.
