A magnitude 9.0 earthquake off the Northwest coast could hit at any time. How can we prepare for this impending and unpredictable disaster?
The U.S. Geological Survey confirmed the earthquake hit about 4 miles (6.4 kilometers) southwest of Silverton at 8:45 p.m. Saturday.
Some nearby residents said they felt the earthquake, which also struck near the state capital city of Salem.
In nearby Mollala, northeast of this site, a magnitude 4.0 quake also hit last December.
Experts have said for years that Oregon and the Pacific Northwest are due for a catastrophic earthquake with a magnitude of 8.0 or higher.
