Geological Circumstances Behind Washington Mudslide

Originally published on Wed March 26, 2014 12:26 pm

As search efforts intensify around the site of Washington state’s devastating mudslide, geologists are looking into causes of the rapid collapse of the 1,500-foot-wide segment of hillside in Snohomish County that suddenly cut away and crushed the homes and roads below.

The chief culprit appears to have been the glacial composition of the hillside, which is made of silt, clay and soil, and very little rock, which tends to be very loose.

It's been a busy summer on the high seas for researchers trying to figure out the inner workings of an ominous earthquake fault. The Cascadia Subduction Zone runs offshore from Vancouver Island to Northern California. When it rips, we could have a magnitude 9 catastrophe.

University of Washington geophysicist Paul Johnson led a nearly month-long research cruise to the likely epicenter for the Big One. His ship carried an unmanned minisub to probe the seafloor directly over the still somewhat mysterious Cascadia earthquake fault.

David Montgomery: "The Rocks Don't Lie"

There are many stories of great floods out there, first and foremost the fable of Noah's ark. But some geologists have found that many of these legends have some basis in historical fact. We talk with University of Washington professor and MacArthur award-winner Dave Montgomery, the author of "The Rocks Don't Lie: A Geologist Investigates Noah's Flood."
