After the California quake, seismologists have warned Washington state should prepare for a big tremor as well.

Harold Tobin, director of the Pacific Northwest Seismic Network at the University of Washington, warned “something similar could happen in Seattle.” 

He told Komo News: “Let’s say one on the coast.

“A big one on the Cascadia fault will be felt strongly in Seattle and will be amplified.

“Our fault that we worry about the most for the really big one for the Pacific Northwest is this offshore fault called the Cascadia Fault or Cascade Subjection Zone.

“That’s the one that could give us the magnitude 9. The big tsunami.”

Both California and Washington State lie on the explosive ring of fire, a horseshoe-shaped area in the Pacific Ocean. 

This area stretches 25,000-miles long and is home to around 90 percent of the world’s earthquakes and more than 75 percent of the world’s active and dormant volcanoes.
