(Oregon Coast) – UPDATE: Tsunami watch for the Oregon coast has been canceled as of about 4:30 a.m. There is NO threat to the Oregon coast.

Below is the original story for reference only.

The National Weather Service (NWS) in Portland has issued a tsunami watch for the southern Washington coast and the north and central Oregon coast, originating around 2 a.m. An 8.2 earthquake occurred in Alaska around 1:30 a.m., centering about 175 miles southeast of Kodiak City, Alaska.

So far this is just a TSUNAMI WATCH, and no evacuation orders have been issued. Wave impact could yet be determined to be small or nonexistent.

More updates will be posted here as well as on the Oregon Coast Beach Connection Facebook page.

UPDATE 4:11 A.M.: USGS is reporting this was not the kind of quake that displaces a lot of water. It was a strike slip quake instead of a subduction quake, which does move a lot of water. That is a good sign, but still to early to say what that means. Currently, scientists are waiting for data from Pacific Northwest buoys before making any further determination.

SMALL UPDATE: We just talked to the NWS and they still do NOT know anything more than this is a watch. There was a .5 foot (six inches appx) tsunami wave in one part of Alaska, but they told us this is NO indication either way, whether this could mean a larger wave or smaller wave in this area - if any wave at all. They simply said the tsunami center people in Alaska are working on it and we'll know as soon as they know anything. One good sign: the tsunami watch for Hawaii was canceled. 

The following is issued directly from the NWS. Oregon Coast Beach Connection is working on updates and more information.
