California quake model looks for ‘mega-quake’ along Cascadia

California quake model looks for ‘mega-quake’ along Cascadia | The Extinction Protocol: 2012 and beyond: "January 11, 2013 – PORTLAND, Or. - New research is giving us some insight into when a major earthquake could strike the Northwest. The research was done in part by Stanford geophysics Professor Paul Segall. He has been tracking a series of very small tremors that rumble deep within the earth. The slow tremors happen roughly every summer along the Cascadia Subduction Zone, an undersea fault about 70 miles off the Oregon Coast. Over the last decade, data shows the tremors have been getting progressively bigger."
