Anchorage Earthquake: No Tsunami Threat For Oregon, Washington

PORTLAND, OR – A magnitude 7 earthquake hit near Anchorage Friday morning, causing shaking and damage across the state's most populous area. A tsunami warning was issued for the Cook Inlet and Kenai Peninsula, but not for other Pacific Northwest states like Washington and Oregon.

According to early reports, buildings were shaken, and some areas lost power. There was no immediate word on injuries.

The quake was originally reported as a magnitude 7.2, but was later downgraded. It is not unusual for the magnitude of earthquakes to be adjusted in the first few hours as more data comes in.

The National Weather Service's Portland Office says that there is no tsunami threat for Oregon and Washington. There was a local tsunami warning in Alaska. It was a particular concern because the quake was considered shallow at 40 kilometers below the surface.
