Massive Mega-Quake could kill 13,000 People and destroy Pacific Northwest

To the north of California’s famous San Andreas fault is a less known, but possibly more deadly, fault line. The Cascadia subduction zone runs some 700 miles from northern California to Vancouver.

In a deeply reported article for The New Yorker, Kathryn Schulz tells the tale of how this fault lies dormant for periods of 243 years, on average, before unleashing monstrous tremors.

The Pacific Northwest is 72 years overdue for the next mega-earthquake, which is expected to be between 8.0 and 9.2 in magnitude and could kill an estimated 13,000 people and destroy a sizable portion of the Pacific Northwest.
