Slight damage at Rio Branco, Brazil. Felt (IV) at Pucallpa, Peru and (III) at La Paz, Bolivia. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=170 Dip=60 Slip=-77 NP2:Strike=325 Dip=32 Slip=-111 Principal Axes: (T) Plg=14 Azm=251 (P) Plg=72 Azm=111 Comment: The focal mechanism is moderately well controlled and corresponds to normal faulting with a small left-lateral strike-slip component. The preferred fault plane is NP1. RADIATED ENERGY No. of sta: 5 Focal mech.
