Searchers Return To Scene Of Washington Mudslide

Searchers are back on the job looking for victims of Saturday’s mudslide in Snohomish County. As of last Sunday night, the death toll was eight, but many others remain missing.

After touring the area by helicopter Sunday, Washington Governor Jay Inslee said the mudslide affects an area of one square mile.

David Montgomery is a geologist at the University of Washington.

He says the same site experienced a landslide in 2006. Montgomery points to the evidence he sees in Google Earth images.

You can see the trace of the edge of the landslide scar that predates the current one. So the slope was already unstable, and it reactivated in a much more dramatic and violent fashion than it seems to have done in the past.

It’s unclear whether residents along the Stillaguamish River near Oso knew of the landslide danger.
