Preliminary results from a study related to the subduction of the Juan De Fuca Plate beneath the North American Plate off the coast of Washington and British Columbia indicate that the potential mega-thrust earthquake could strike closer to the Seattle-Tacoma area than previously thought. I believe this project is the same one where I posted their press release about two years ago. According to the article, the average return period for these mega-thrust earthquakes is 400 to 500 years with a range between 300 and 800 and the estimated magnitude of around 9.0. The last mega-thrust earthquake along the Cascadia Subduction Zone was in January of 1700. Previously, scientists predicted the earthquake would be centered just off the coast, they now think it could be 30 miles or more inland, under the Olympic Peninsula to the west of the Seattle-Tacoma area.

A magnitude 7 earthquake struck just 8 miles north of Anchorage, Alaska this morning causing widespread damage to buildings and infrastructure. The quake struck at 8:29 am local time and the focus of the earthquake […]
The NSF funded Geotechnical Extreme Events Reconnaissance (GEER) team has provided a preliminary report and some amazing photos and video of the damage to various regions of Japan affected by the moment magnitude 9.0 earthquake that struck on March 11, 2011. Read on to see some amazing photos and video of the liquefaction damage related to the Tohoku Earthquake in Japan. (Photos from Oregon State Flickr)
A magnitude 8.2 earthquake struck off the coast of Chile late Tuesday. The damage estimates will probably begin rolling in today, but early indications are that it could have been much worse. Some 5 people […]
