M 6.1 - 61 km ENE of Yigo Village, Guam

Felt (IV) on Guam. FAULT PLANE SOLUTION: P-Waves NP1:Strike=38 Dip=82 Slip=90 NP2:Strike=218 Dip=8 Slip=90 Principal Axes: (T) Plg=53 Azm=308 (P) Plg=37 Azm=128 Comment: The focal mechanism is poorly controlled and corresponds to reverse faulting. The preferred fault plane is NP2.
