M 6.6 - 34 km SW of Pedernales, Ecuador

Some damage (VI) in the Jama-Bahia area. Felt (V) at Chone and (IV) at Guayaquil. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=160 Dip=82 Slip=90 NP2:Strike=340 Dip=8 Slip=90 Principal Axes: (T) Plg=53 Azm=70 (P) Plg=37 Azm=250 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.
