Oregon Earthquake

A mild 4.9 richter quake 130 miles offshore from Bandon this am -- along the edge of the Juan de Fuca Plate, an offshore oceanic plate slowly sliding easterly against and subducting under the westerly-moving North American Plate. This quake, with an epicenter about 30 km below the sea floor, was along a side-by-side moving lateral fault bounding the Juan de Fuca.

It is a reminder that the Pacific Northwest is an active zone of faulting and earthquakes and that there is seismic risk ashore and tsunami risk along the coasts. Good for all in the area to understand that there is a (slight) risk and to know what to do regarding quakes on land and with tsunamis when on our boats. Forewarned is forearmed -- a little knowledge can save lives (and boats).

See you all in Seattle this weekend. Your resident geologist.
 
Wow, musta been a reaction to the Anderson boat purchase. Pat did say he'd only buy another boat when the earth moved.... :shock:

See you and El at the SBS! :lol:

when is the big one going to hit? Over the holiday we condoed out in Ocean Shores WA. I asked the manager about tsunamis and was informed that their computer was hooked up to NOAA. If the big one hit, the phones in all the rooms would ring and warn you. Her recommended evacuation plan consisted of grabbing the best scotch and heading for the fourth floor.
 
Mt Saint Augustine in the Cook Inlet apparently erupted this morning. We're waiting for daylight to see how much steam and ash was involved.
 
Here's all the pictures of Augustine and here's the seismic activity. Very interesting...

Augustine Seismic Activity

The activity is for the 10th and 11th but it looks like the pix are from the 4th. Maybe a typo?

On further reading, this puppy has been active for about a month and is increasing.

Pat, I think if you go up there this summer, you ought to have at LEAST a C-Ranger, if not a C-Nordic Tug. It s justs across the mouth from Port Graham..... :lol:

I didn't realize how many earthquakes occur in Alaska, either, until I started reading the weekly earthquake report in the Fairbanks paper. I guess we get hundreds of them each month. But because this state is sooooo big and is so sparsely populated and so far away from the lower 48 that most quakes just don't make the national news. It's not uncommon to see ash plumes from one of the several volcanoes along the west side of the Cook Inlet when we're down on the Kenai Peninsula, either.

Heck, it's just an interesting place to live, that's all.
