Fasten your seatbelts!

Quake shockwave (1.1Mb animated .gif)If you live in the Seattle/Portland/Pacific Northwest — or Japan — you might want to think about moving. At least, think about it if you have plans to be in the area in about 200 years. ;)

Geologists have discovered evidence of a massively powerful earthquake zone beneath the Pacific Northwest just offshore from the Seattle area.

They made the discovery by piecing together ancient accounts of a giant Japanese tsunami and a computer simulation of a huge trembler in the 17th century.

Thought to be inactive, the earthquake zone runs 600 miles up the Pacific Coast from Northern California to southern British Columbia. It appears to be subject to monster quakes every 500 years.

In Japan, Satake created a detailed computer model showing how the tsunami crossed the Pacific before crashing into Japan.

Atwood said the geological record indicates the fault ruptures about once every 500 years and is capable of unleashing “truly giant earthquakes.”

He said only three quakes this century compare in magnitude — a 9.0 quake in Kamchatka in 1952, a 9.5 quake in Chile in 1960 and a 9.2 trembler in Alaska in 1964.

Well, okay, so maybe there’s not great reason to panic just yet. Alaskans have been expecting a repeat of the ’64 quake “real soon now” for years without it happening, and this one isn’t due for another two centuries. Still, it’s nice to be able to plan ahead sometimes, isn’t it?
