Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=8 Dip=75 Slip=-110 NP2:Strike=243 Dip=25 Slip=-38 Principal Axes: (T) Plg=27 Azm=114 (P) Plg=56 Azm=253 Comment: The focal mechanism is poorly controlled and corresponds to normal faulting with a moderate right-lateral strike-slip component. The preferred fault plane is NP1. RADIATED ENERGY No. of sta: 19 Focal mech.
