Two events about 5.8 seconds apart. Depth from broadband displacement seismograms based on first event. FAULT PLANE SOLUTION: P-Waves NP1:Strike=320 Dip=65 Slip=-180 NP2:Strike=50 Dip=90 Slip=-335 Principal Axes: (T) Plg=17 Azm=278 (P) Plg=17 Azm=182 Comment: The focal mechanism is moderately well controlled and corresponds to strike-slip faulting with a moderate normal component. The preferred fault plane is not determined. RADIATED ENERGY No. of sta: 5 Focal mech.
