Oct 24, 2009 - SEATTLE -- The fault line under Seattle could be bigger than anyone thought, according to new research conducted by a University of Washington graduate student. Beth Martin found evidence that could mean quakes along the fault line could be larger, and even trigger a tsunami. The Nisqually earthquake that rocked the Northwest eight years ago was a 6.8 magnitude. The quake, centered deep in the Earth, caused a lot of shaking and some damage. But the ground didn't rise up like it did 1,000 years ago. That's when scientists believe a 7- to 7.5-magnitude earthquake hit the more shallow Seattle fault zone that runs from Sammamish, through Seattle and out toward Bremerton. FULL STORY
