A long-feared monster earthquake off the coast of California, Oregon and Washington could cause some areas to sink by more than 6 feet, dramatically heightening the risk of flooding.

A major earthquake may strike the Pacific Northwest region resulting in sinking the coastal land by almost seven feet, forcing people to face severe flooding in the area, as per a recent study. The lead author suggests the disaster could be "on the scale of" what happened in 2004 in Sumatra and in 2011 in Japan.

This should have West Coasters shaking in their shoes. Hundreds of miles of coastline in the Pacific Northwest could go straight into the drink if another major earthquake strikes the region, an alarming new study warned.
