February 14, 2012 – A Rare 6.0 Earthquake Struck off the Coast of Oregon, USA: About two hours ago, a 6.0 magnitude quake struck off the west coast of Oregon, at a depth of 10 kilometers (6 miles).
This quake occurred in the complex fault system off the west coast of Oregon, Washington State and British Columbia, Canada (see maps).
The tremor hit along the transform Blanco Fracture Zone fault (strike/slip) between the Juan de Fuca ridge and the Mendocino fracture Zone; which is an extension of the San Andreas Fault.
The quake was 159 miles west of Coos Bay, Oregon; 187 miles northwest of Brookings, Oregon; 203 miles northwest of Crescent City, California; and 271 miles WSW of Portland, Oregon.
It was 10:31PM in New York, 9:31PM in Chicago, 8:31PM in Denver and 7:31 in Los Angeles.
The real danger here is that the Juan de Fuca ridge and the Subduction Zone that runs off the coast of Oregon, Washington State and British Colombia, Canada; has not had a major release in hundreds of years. Any large event along the Subduction Zone that runs just off shore would be catastrophic in that the major population centers along the Northwest coast of the United States would have only minutes in warning time.
