Depth from broadband displacement seismograms. FAULT PLANE SOLUTION: P-Waves NP1:Strike=300 Dip=90 Slip=177 NP2:Strike=30 Dip=87 Slip=360 Principal Axes: (T) Plg=2 Azm=255 (P) Plg=2 Azm=345 Comment: The focal mechanism is moderately well controlled and corresponds to strike-slip faulting. The preferred fault plane is not determined. RADIATED ENERGY No. of sta: 10 Focal mech.
