Tsunami “Wave” Passes Down Oregon Coast

The only part of the Pacific under a Tsunami warning at 11:45pm is Hawaii.  It’s only an advisory everywhere else from Alaska to California.

The small wave from the earthquake off the BC Coast moved down the Oregon Coast between 10-11pm.  Here are the  heights reported by NOAA:

Looks like the tsunami passed down the Oregon Coast between 10-11pm (0500-0600z).  Peak wave heights, with the initial wave at least, were below 1 foot:

 CHARLESTON  OR       0524UTC   00.3FT
 GARIBALDI  OR           0515UTC 00.2FT
 LA PUSH  WA              0448UTC   00.4FT
 NEAH BAY  WA            0530UTC   00.3FT
 PORT ORFORD  OR      0519UTC   00.5FT
 SOUTH BEACH  OR       0524UTC   00.3FT
 CRESCENT CITY  CA     0555UTC   00.6FT

You can see a model forecast of the wave energy; most of it heading SW towards Hawaii where  a warning is still in effect.

7.7 Quake West Coast of B.C…No Tsunami Threat

And impressive 7.7 magnitude quake struck about 90 minutes ago (sorry, I was Netflixing…) in the Haida Gwaii (Queen Charlotte) islands off the coast of British Columbia.  It was right along a main fault, well to the north of the Cascadia Subduction Zone.  2 aftershocks have followed.  The 7.7 was a 8:04pm, a 5.8 10 minutes later, then a 4.8 at 8:52pm.  The ground is rearranging itself up there!

There is still a Tsunami Warning for extreme SE Alaska and the central coast of British Columbia, but there has not been a threat this far south.  So no warning, watch, or advisory for our coastline.
