M 6.7 - 15 km S of Murindó, Colombia

About 20 people injured and 90 percent of the buildings destroyed at Murindo. Felt throughout northwestern Colombia from Cali and Bogota to Cesar Department. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=35 Dip=63 Slip=90 NP2:Strike=215 Dip=27 Slip=90 Principal Axes: (T) Plg=72 Azm=305 (P) Plg=18 Azm=125 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is not determined. RADIATED ENERGY No. of sta: 13 Focal mech.
