Clock is ticking on next massive Pacific Coast earthquake
In one study, a 13-year comprehensive analysis of the Cascadia earthquake-prone zone between Vancouver Is-land and Northern California, a team of researchers led by Oregon State University Earth scientist Chris Goldfinger concluded that the "clock is ticking" ahead of a potentially devastating earth-quake in the region within the next 50 years. In a 184-page report published this week by the U.S. Geological Survey, the team compiled a detailed record of earthquakes in the region going back to 8,000 B.C.
"Over the past 10,000 years, there have been 19 earth-quakes that extended along most of the margin, stretching from southern Vancouver Island to the Oregon-California border," Goldfinger stated in a summary of the study.
"These would typically be of a magnitude from about 8.7 to 9.2 - really huge earth-quakes."

“If one is closer to the rupture area of an earthquake, then the ground shaking will be more intense, all other things being equal,” study co-author Glenn Spinelli, a research scientist with the New Mexico Institute of Mining and Technology, told Postmedia News. “Therefore, if the rupture area of a Cascadia subduction zone earthquake is closer to land, then the shaking on land will be greater.”
He added that the southern margin of Cascadia, encompassing southern Oregon and Northern California, “has a much higher recurrence level for major earthquakes than the northern end and, frankly, it is overdue for a rupture.”
But he cautioned: “That doesn’t mean that an earthquake couldn’t strike first along the northern half, from Newport, Oregon, to Vancouver Island."

Personally think we will have M 8.0 + in that areas in next 2 years, probably off coast Oregon ..
