What's The Largest Quake Ever In Washington?

By By Steve Pool

SEATTLE - Most of us remember the 6.8 Nisqually Quake of 2001, which was the largest in a while, but historically, there have been even larger quakes -- including a 7.1 quake centered near the same spot near Olympia on April 13, 1949.

But the largest quake ever recorded in our area occurred Jan. 26, 1700 off the Washington Coast. No one has an exact magnitude, but it's estimated at over 9.0. It dropped the coastal floor 3-6 feet and caused a huge tsunami to strike Japan.

Closer to Seattle, seismologists have found evidence of a quake measuring around 7.4 about 1,100 years ago on a fault that runs through Seattle. While quakes of those size are incredibly rare, it's a good reminder to always be prepared.

This was a once-in-a-lifetime shot of a brilliant sunrise on the water of Poulsbo. When I saw the pink light streaming into my window early that morning, I ran outside to capture this photo. Once I saw the photo, I realized that the sunrise created a fire and ice effect that was stunning.

Driving toward Silverdale on Hwy 3, from brilliant fall sunshine, into this churning black storm, was unlike anything I've witnessed in Washington. Sheets of rain, gusts of wind, and a completely black sky overtook the area, while the periphery stayed sunny.
