FAULT PLANE SOLUTION: P-Waves NP1:Strike=125 Dip=75 Slip=-3 NP2:Strike=216 Dip=87 Slip=-165 Principal Axes: (T) Plg=8 Azm=349 (P) Plg=13 Azm=81 Comment: The focal mechanism is poorly controlled and corresponds to strike-slip faulting with a moderate normal component. The preferred fault plane is not determined.
