Earthquake fault much larger, more dangerous than thought | McClatchy: "Scientists believe a 9.0 quake rocked the Cascadia subduction zone, where two tectonic plates collide just off the west coast, on Jan. 26, 1700, producing a giant tsunami that hit Japan. A similar quake, which could produce a tsunami of 60 to 90 feet that would hit the northwest coast in 15 minutes or less, is considered likely, though scientists aren't sure when."
