A whole lot of shaking took place early Sunday morning off the South Oregon Coast. According to the U.S. Geological Survey, a series of earthquakes shook the Pacific Ocean sea floor on the outer fault line of the two that run parallel with the Oregon Coast. The largest measured 5.1-magnitude and it was located west of Bandon at a depth of six-miles. That quake was followed by a 4.9-magnitude and a 3.4-magnitude in the same area. Two other quakes shook the southern junction of the two fault lines Saturday. A 2.8-magnitude west of Ferndale, CA, and a 2.5-magnitude southeast of Petrolia, CA, both near Cape Mendocino in Northern California.
