It's the earthquake that will, in many ways, "mirror" the one that devastated Japan in 2011:
More than 10,000 people could die when—not if—a monster earthquake and tsunami occur just off the Pacific Northwest coast, researchers told Oregon legislators Thursday.
Coastal towns would be inundated. Schools, buildings and bridges would collapse, and economic damage could hit $32 billion.
The last time a monster earthquake happened in the Cascadia Subduction Zone was in 1700. Which means, according to the experts, we're "overdue."
