The red line shows an area of the nine-meter slip 25 kilometers deep in the crust, as predicted by James Chapman and Timothy Melbourne of Central Washington University. The green line runs down where the slip dissipates to zero as the fault deepens to the east. updated 7:23 p.m. ET Oct. 27, 2009 The Cascadia thrust fault, one of the most dangerous and powerful faults on Earth, will hit even closer to home than anyone thought possible, according to a new study. If the new findings are accurate, the fault will rupture within 68 miles of downtown Seattle, pouring seismic energy into a densely populated urban area, threatening to knock down buildings both large and small, and endangering the lives of the city's nearly 10 million residents. The threat of earthquakes is just a part of life for those living in Seattle, Vancouver and throughout the Puget Sound region. Scientists know it is just a matter of time before Cascadia lets loose a devastating quake on the order of magnitude 9.0.
