In Your Lifetime
There is a HIGH CHANCE (84%) of a magnitude 6.5+ deep earthquake hitting in the next 50 years. It will feel similar to the M6.8 Nisqually Earthquake in 2001. Very strong shaking will make it hard to stand here. Furniture will move and many objects will fall from shelves. Damage will be significant in poorly built structures and slight to moderate in ordinary structures. (map)
There is a MODERATE CHANCE (10-30%) of a magnitude 8+ Cascadia earthquake hitting the Northwest in the next 50 years. When it does, you will feel very strong shaking that persists for minutes here. Standing will be difficult and many will be injured. Bricks and shattered glass will litter the streets. Power and water will be off for days to weeks. (map)
What's the Worst?
A LOW CHANCE (5%) exists of a magnitude 7+ earthquake on the Seattle Fault in the next 50 years, but if it does it will be damaging. Severe shaking will make it hard to stand or drive. Heavy furniture will be overturned. Parts of URM buildings will collapse and wood frame houses will shift on foundations.(map)
Potential: LOW - MODERATE
Some potential exists for liquefaction here. Shaking could cause soil to become unstable. Roads may crack and become damaged.(map)
Scientists cannot predict when an earthquake will happen so be aware and if you feel shaking, drop cover, and hold on. An early warning system is currently being developed for the West Coast. You can find out more here.
