Risk of mudslides in the Rogue Valley

Ashland, Ore. — The fatal mudslide in Washington over the weekend now has local geologists looking at the possibility of slides in southern Oregon and northern California.

Geologist Eric Dittmer says mud and landslides can happen just about anywhere, more particularly if there’s a slope in the land, like a hill or mountain. And they’re usually caused by heavy, constant rain.

Area’s burnt by wildfires are even more at risk.

“Because the roots structure of plants, especially trees, tendhold the soil in place, and if you have a fire and those trees are gone then the soil is vulnerable,” Dittmer said.

Maps from the Oregon Department of Geology and Mineral Industries shows areas across the state that have an increased risk for slides, many right here in the Rogue Valley.

Dittmer saysthe only way to be prepared is to educate yourself before moving into a home near a slope.

He suggests having an engineering geologist look at the land and assess it’s potential for instability and the potential for a landslide.
