An alarming report published by the Oregon Seismic Safety Policy Advisory Commission warns about the dire effects of the quake and claims that it is imminent and could strike anytime. The report, which was compiled by a group of more than 150 volunteer experts, was requested by the Oregon legislature in order to adequately prepare for the looming disaster.

The last high magnitude earthquake in the region occurred in the year 1700 in the Cascadia Subduction Zone. The quake had a magnitude between 8.7 and 9.2, and geologists in 2010 predicted that there is a 37 percent change of another such quake occurring within 50 years. The new report claims that there is a 100 percent chance of a monster earthquake occurring in the region – but scientists don’t know when.
