6.0 Magnitude EQ – Off the Coast of Oregon

A strong 6.0 magnitude earthquake struck on Tuesday roughly 160 miles off the coast of Oregon, the U.S. Geological Survey said. This earthquake comes one day after a 5.6 magnitude quake rattled Northern California near the Pacific Coast.

A 4.2 magnitude earthquake struck off the coast of Vancouver Island toward the northern edge of the Juan de Fuca plate earlier in the day on February 14 at 2:54 p.m. local time.

With all quakes, being prepared and having a plan is the only true defense as a quake can happen at any time.

At approximately 03:31:20 UTC on Wednesday, February 15th, the 6.0 magnitude earthquake based on water struck at a depth of 10.0 km (6.2 miles) off the coast of Oregon, 256 km (159 miles) W of Coos Bay, Oregon. Coords: 43.536°N, 127.381°W

The 1700 Cascadia earthquake was a magnitude 8.7 to 9.2 megathrust earthquake that occurred in the Cascadia subduction zone on January 26, 1700. The earthquake involved the Juan de Fuca Plate underlying the Pacific Ocean, from mid-Vancouver Island in British Columbia, Canada, south along the Pacific Northwest coast as far as northern California, USA.

The length of the fault rupture was about 1,000 kilometers (620 miles) with an average slip of 20 meters (22 yards).

The earthquake caused a tsunami that struck the coast of Japan, and may also be linked to the Bonneville Slide.
