Computer simulation shows destruction from Oso landslide

VANCOUVER, Wash. -- The U.S. Geological Survey has released a preliminary computer simulation of last month's Oso mudslide.

The 30-second-long animation tracks a possible path of the debris as it left a hillside and flowed over about one square mile of land around the North Fork of the Stillaguamish River.

According to the model, most of the affected area was covered by debris less than 90 seconds after the slide began.

The blue and white areas represent the debris flow. Darker colors indicate the flow is deeper.

The simulation was produced by the USGS Cascades Volcano Observatory in Vancouver, Wash.
