Felt (V) at Huacho; (IV) at Lima and Trujillo; (III) at Canta and Huaraz; (II) at Chiclayo and Ica. Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=3 Dip=73 Slip=-90 NP2:Strike=183 Dip=17 Slip=-90 Principal Axes: (T) Plg=28 Azm=93 (P) Plg=62 Azm=273 Comment: The focal mechanism is poorly controlled and corresponds to normal faulting. The preferred fault plane is NP1. RADIATED ENERGY No. of sta: 11 Focal mech.
