Whose fault is this - found a new one in Eastern Washington

From our local Bellingham Herald:

Scientists may be cracking mystery of big 1872 earthquake
Geologists might be close to cracking one of the biggest seismological mysteries in the Northwest: the origin of a powerful quake that rattled seven states and provinces when Ulysses S. Grant was president and the transcontinental railroad hadn’t yet reached Washington.

Preliminary evidence points to a newly discovered fault near Entiat in Chelan County. The find adds to a growing body of evidence that Central and Eastern Washington are more quake-prone than previously thought, and will help refine seismic risks in an area that’s home to 1.5 million people, more than a dozen hydropower dams and the Hanford nuclear reservation, said Craig Weaver, regional chief of the U.S. Geological Survey’s (USGS) earthquake programs.

“For more than four decades, people have been guessing where the 1872 earthquake was,” Weaver said. “To be able to finally pinpoint this thing on a map would be really important in helping us get the seismic hazard assessment correct in that part of the state.”

Emphasis mine - yikes! A lot of the problems at Hanford are the waste storage tanks holding liquid radioactive waste. Some of these are seeping into the Columbia River.  A big quake would flood the area down to Portland and the Pacific Ocean. We have been vitrifying this waste into a solid glass but since no site for long-term storage has been designated (thanks a lot Harry Reid), we have not progressed as far as we should have.
