M=4.7 quake in Gulf shakes Rocky Point (Puerto Penasco)

A magnitude 4.7 earthquake in the Gulf of California shook the beach resort town of "Rocky Point" (Puerto Penasco, Sonora, Mexico) 40 miles to the north. The quake occurred at 5:32 AM local time.

The Gulf is tectonically active with spreading centers and transform faults, but the quake appears to be off the main fault lines. [Right, location map from USGS]
