SEATTLE - A team of scientists says intense rainfall likely played a major role in triggering a deadly landslide in the state of Washington.
The report released Tuesday says many other factors such as previous landslide activity also weakened the slope that collapsed on March 22, killing 43 people in Oso about 55 miles northeast of Seattle.
The team says the slide, the deadliest in U.S. history, occurred in two major stages. A fast-moving mudflow remobilized a 2006 slide, bringing down old slide deposits across the valley. Another slide followed a few minutes later.
The report makes several broad recommendations that include doing an examination of landslide risks and communicating the information to the public.
- North Idaho millionare's estate up for auction
- Many seniors, mentally ill patients losing affordable housing
- Demand for new homes increasing, as is need for skilled workers and land
- Pickup plunges over 200-foot cliff, killing driver
- Domestic violence suspect flees after high speed chase
- Two men charged with burglarizing home
