Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=235 Dip=90 Slip=16 NP2:Strike=145 Dip=74 Slip=180 Principal Axes: (T) Plg=11 Azm=101 (P) Plg=11 Azm=9 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.
