PORTLAND -- The devastating landslide in Washington has a lot of people wondering if something similar could happen in the Portland metro area.

State geologist Bill Burns said Portland’s Washington Park was one example of a local area with major slide potential.

Burns said a huge section of the park that once slid, has continued to move. And, like the Oso area, Washington Park contains a massive, deep-seeded ancient slide.

“Throughout time, portions may move or the whole thing may move. We don’t know,” Burns said. “But we do know that it’s very common for these large landslides to reactivate, just like this one up in Washington did.”

However Burns added that he does not think the land in Washington Park shows signs of moving at any moment - like Oso did.

He said that it would take an earthquake or a massive and prolonged rain event to cause that kind of movement.
