6.0 magnitude earthquake hit off the Southern Oregon coast Monday night

Wow, Its time to get prepared..

[box] A strong 6.0 magnitude earthquake hit off the Southern Oregon coast Monday night.

The earthquake occurred at 7:31 p.m., approximately 152 miles northwest of Bandon and 271 miles southwest of Portland, the U.S. Geological Survey National Earthquake Information Center (NEIC) reports. It happened at a depth of 6.2 miles below the earth’s surface.

The earthquake was not expected to start a tsunami, according to the West Coast and Alaska Tsunami Warning Center. 

This is an area where there have been hundreds of earthquakes that have been documented, but quakes above 6.0 are rare,” KOIN Chief Meteorologist Bruce Sussman said.  What geologists don’t know is if this is releasing pressure, or increasing pressure for an even bigger quake off the Oregon Coast in the future.”

USGS Map showing M6.0 Location Feb 14 2012

Magnitude 6.0
Location 43.536°N, 127.381°W
Depth 10 km (6.2 miles)
Distances 256 km (159 miles) W of Coos Bay, Oregon
293 km (182 miles) WSW of Newport, Oregon
302 km (187 miles) NW of Brookings, Oregon
380 km (236 miles) WSW of SALEM, Oregon

That’s the official word from the USGS after a M6.0 earthquake hit off the Oregon coast tonight.

Here in Portland, where this is being written, nothing was felt – but that’s not surprising considering the ‘quake was to the south and out to sea.

Nevertheless, it clearly indicates that activity continues to build around the Ring of Fire – and without intending to be alarmist, it suggests that we can expect more of this magnitude, if not higher, before long. If you haven’t done so yet, it really is time to prepare as best you can for bigger earthquakes.

The image above gives a clearer picture of the undersea terrain where the earthquake occurred. It’s known as the Bianca Fracture Zone. Almost exactly a year ago it was  reported that  “Damaging tsunami waves of more than 6 feet could hit spots along the Oregon coast as the ocean surges after a massive (M9.0)  earthquake in Japan.”

There are no reports of tsunami warnings after tonight’s earthquake off the Oregon coast, but the potential exists.

We’re also hearing that  “A strong Mexico earthquake today was felt in Southern California and Arizona. The terremoto today, February 14, 2012 struck Baja Mexico, and could be felt in sections of Southern California east of San Diego.( Mexico Earthquake, Terremoto, Today Felt in California, Arizona)
