EXERPT:
This week the U.S. Geological Survey published new nationwide hazard maps. One of the changes centered on the Cascadia Subduction Zone off the Oregon Coast.
Video: Big One to be Bigger
In the past scientists believed there would likely be several smaller earthquakes along that fault line. But this new research shows evidence the entire subduction zone could shake all at once resulting in a magnitude nine earthquake.
Note:
I have never read or heard them suggest anything less than a M9.5, the alterations have always been leaning toward a greater magnitude, 10-12, which is off the present scale.
