We felt it hear in Quilcene, WA.... we actually live on the Toandos, or Coyle Peninsula as the locals know it.
The Toandos/Coyle is the peninsula across from Bangor sub base. We live on the west side of the peninsula (opposite side from Bangor) about even w/ the southern tip of the Bolton Peninsula just east of us.
Anyway, more correct to say my wife who was sleeping felt it, it actually woke her up. I actually did not feel it (guess I am kind of insensitive like she always says!) but I heard the wine glasses clinking in the next room.
Take care,
Dan

Dave,
Some folks felt it pretty good in Sequim, but I didn't notice anything west of Port Angeles.

Now I read that Alaska is about to have a volcano blow off any day. Is this a big concern? Its a 100 miles away from the city but what damage can it cause? I dont trust the news for a true report. They hype everything out of porportion. So what say the northen brats.

Earthquakes in the PNW are not unusual, as you folks there know. We had a good discussion of earthquakes and tsunamis (and steps to be taken if you are exposed to either) awhile ago on this site and it might be worth a review for those of you in earthquake country:

The last known very large earthquake in the northwest was in January, 1700, just over 300 years ago. Geological evidence indicates that great earthquakes may have occurred at least seven times in the last 3,500 years, suggesting a return time of 400 to 600 years. But, earthquakes obviously aren't on any specific schedule. So the smaller ones, like today, are just a reminder to know what to do in case of a big one, and be prepared.

Tom-
The big concern that far away is that volcanic ash can travel hundreds of miles! Remember Mt St. Helens in 1980?
Folks up there are bracing for the eruption by buying dust masks and eye protection to get ready for the enivitable:
Alaskans Brace for Redoubt Volcano Eruption

The volcano, about 100 miles soutwest of Anchorage, is rumbling and simmering, prompting geologists to warn that an eruption may be imminent. (AP Photo/Al Grillo, File)

"Alaskans Brace for Redoubt Volcano Eruption
Friday, January 30, 2009 5:30 AM EST
The Associated Press
By DAN JOLING Associated Press Writer
ANCHORAGE, Alaska (AP) — Hardware stores and auto parts shops scored a post-holiday run of business this week as Anchorage-area residents stocked up on protective eyewear and masks ahead of a possible eruption of Mount Redoubt.
Monitoring earthquakes underneath the 10,200-foot Redoubt Volcano about 100 miles southwest of Anchorage, scientists from the Alaska Volcano Observatory warned that an eruption was imminent, sending experienced Alaskans shopping for protection against a dusty shower of volcanic ash that could descend on south-central Alaska.
"Every time this happens we do get a run on dust masks and goggles," said Phil Robinson, manager of an Alaska Industrial Hardware store in Anchorage. "That's the two main things for eye and respiratory protection."
Customer Ron Cowan picked up gear at the store Thursday before heading off to an auto parts store for a spare air filter.
"I'm older now and I'm being a little more proactive than I was the last time," Cowan said.
When another Alaska volcano, Mount Spurr, blew in 1992, he waited too long.
"The shelves were cleared, so I thought I wouldn't wait until the last minute," Cowan said.
Unlike earthquakes, volcanoes often give off warning signs that usually give people time to prepare.
The observatory, a joint program between the U.S. Geological Survey, the University of Alaska Geophysical Institute and the state Division of Geological and Geophysical Surveys, was formed in response to the 1986 eruption of Mount Augustine.
It has a variety of tools to predict eruptions. As magma moves beneath a volcano before an eruption, it often generates earthquakes, swells the surface of a mountain and increases the gases emitted. The observatory samples gases, measures earthquake activity with seismometers and watches for deformities in the landscape.
On Nov. 5, geologists noted changed emissions and minor melting near the Redoubt summit and raised the threat level from green to yellow. It jumped to orange — the stage just before eruption — on Sunday in response to a sharp increase in earthquake activity below the volcano.
Alaska's volcanoes are not like Hawaii's. "Most of them don't put out the red river of lava," said the observatory's John Power.
Instead, they typically explode and shoot ash 30,000 to 50,000 feet high — more than nine miles — into the jet stream.
"It's a very abrasive kind of rock fragment," Power said. "It's not the kind of ash that you find at the base of your wood stove."
The particulate has jagged edges and has been used as an industrial abrasive. "They use this to polish all kinds of metals," he said.
Particulate can injure skin, eyes and breathing passages. The young, the elderly and people with respiratory problems are especially susceptible. Put enough ash under a windshield wiper and it will scratch glass.
It's also potentially deadly for anyone flying in a jet. "Think of flying an airliner into a sandblaster," Power said.
Redoubt blew on Dec. 15, 1989, and sent ash 150 miles away into the path of a KLM jet carrying 231 passengers. Its four engines flamed out.
As the crew tried to restart the engines, "smoke" and a strong odor of sulfur filled the cockpit and cabin, according to a USGS account. The jet dropped more than 2 miles, from 27,900 feet to 13,300 feet, before the crew was able to restart all engines and land the plane safely at Anchorage. The plane required $80 million in repairs.
The observatory's first call after an eruption is now to the Federal Aviation Administration. The observatory's data collection has become far more advanced in 19 years, as has the alert system.
"Pilots are routinely trained to avoid ash and in what to do if they encounter an ash cloud," Power said. "That kind of thing was not routinely done in the 1980s."
The jet stream can carry ash for hundreds of miles. Ash from Kasatochi Volcano in the Aleutians last August blew all the way to Montana and threatened aircraft, Power said.
Particulate is mildly corrosive but can be blocked with masks and filters.
Power advises Alaskans to prepare as they would for a bad snowstorm: Keep flashlights, batteries and several days' worth of food in the house, limit driving and prepare to hunker down if the worst of an ash cloud hits.
Merely going indoors is a defense against ash. The American Red Cross recommends wearing long-sleeved shirts and long pants outside, plus goggles and glasses instead of contact lenses. If no dust mask is available, an effective respiratory filter is a damp cloth over nose and mouth.
But potential danger all depends on the wind. Mount Spurr erupted three times in 1992. When it blew that June, only climbers on Mount McKinley — about 150 miles north of Anchorage — were affected, Power said. An August eruption dumped significant ash on Anchorage and a September blow sent ash about 40 miles north of Anchorage to Wasilla.
Dust mask customer Elizabeth Keating said Thursday that if the volcano erupts, she expects to stay inside. She bought masks for her school-age grandchildren to carry in their backpacks.
"I want to make sure they're carrying these in case they're en route," she said."
Yeah, what Bill said, and just a note that today's quake occured deep under Puget Sound, and the really big feared quake will probably occur offshore where the plates collide and are being crushed, generating not only a very large quake, but a big tsunami along with it. There was a discussion of this previously here:Tsunami

I read te same story of course. What I want to know is if anyone that lives there is worried or not? and what cities are down wind of that sucker? I dont know the wind patterns up there.
Face masks and car air filters are flying off the shelves, and the web site for monitoring Redoubt volcano has gone down from too many hits. http://www.avo.alaska.edu/
Fortunately Anchorage is far enough away that ash fallout is usually minimal, but across the inlet in Homer, Kenai, and Soldotna hackles are elevated.
News flashback 1989:
Jet Lands Safely After Engines Stop in Flight Through Volcanic Ash
All four engines of a KLM Boeing 747 temporarily shut down yesterday when the jumbo jet flew through a cloud of ash from the erupting Redoubt Volcano in Alaska, Government officials reported.
The huge airliner descended from 25,000 feet to 12,000 feet in eight minutes before the crew was able to restart two of the engines, and all four were operating when the plane, traveling from Amsterdam to Tokyo, landed at 12:25 P.M. in Anchorage, where it had been scheduled to stop for refueling.

I’m not worried, and the vast majority of old-time Alaskans are probable just taking it all in stride; we’ve been through many eruptions over the years. As for were the ash will fall it depends a lot on how high the plum goes along with current weather and atmospheric conditions.
You have to understand this volcano is pretty predictable based on historical data and current seismic activity. When the site comes back on line you can monitor the seismic activity in real time, and pretty much tell when the top is about to blow.

i think i felt it in ohio as well, or maybe, it was just one of those snow plow trucks driving by the office. at any rate, have a great weekend!

breausaw Triple J,
Now, that's a fast way to get to your refueling destination. They were lucky to get one engine restarted, let alone two and then the remaining two. I like what the investigators stated...it looked like the plane had been sand blasted. Yeah, that's pretty much what did, in fact happen.
