Scientists defining Cascadia Subduction Zone

Ap News

GRANTS PASS, Ore. – Scientists are back from a month long research cruise in the Pacific Ocean off Washington state, where they were trying to find the stickiest point on a section of the Cascadia Subduction Zone.

The huge undersea fault breaks loose every few hundred years, generating a massive tsunami and earthquake.

Paul Johnson, a professor of geophysics at the University of Washington, was one of the principal scientists.

He says it will be some time before the data from deep-sea measurements of heat and gas emissions is fully analyzed.

But preliminary indications suggest the strongest upheaval will be farther out to sea than previously thought.

That is important because the farther out to sea the upheaval occurs, the bigger the tsunami, but the less damage on land from the earthquake.
