"Mon Jul 19, 9:35 AM ET
STRASBOURG (AFP) - A major earthquake, measuring 6.2 points on the Richter scale, hit Vancouver Island off the Pacific coast of Canada, a French seismological institute reported.
The epicentre of the earthquake was at 49.69 degrees North and 126.90 degrees West, about 300 kilometres (190 miles) northwest of Vancouver city, the Strasbourg-based Observatory of Science and the Earth said in a statement..." (End Yahoo.com News Excerpt)

Yes thank you for pingig me.
The scientist are saying the same about this one and the prior one in the last few days in the same area as they are about the two that his right off of the Oregon Coast.
Not standard...hmmmmmmmmm.
I saw it on my now many times a day check to USGS and the sure have been slow to get these up on the world list. IMO
Say I cannot fing the tsunami govt warning page......Anyone have a link it would be a big stress reliever for us.
Uh I was when the quake hit us on the Oregon Coast last week.
Got up and went into emergency mode did finally borrow my son's attends large wipes a few hours later to wipe up, still have a sore bottom.

That is what they said about the two off of Oregon Coast last week, the local paper had artcles stating that the place is not a usual area and they are not conclusive on what to think.
Our coast has a tsunami emergency alert but the raido could not get any info or confirmation and the County website did not have any info the local paper chewed out the Commisioners for the lack of emergency preparedness and we already have a plan in action. City hall phone lines jammed.
My freind who owns a rv/boat resort has decided my road is going to be the high ground road she uses since it is well kept and paved/trees removed ect.
Thank You your a good freeper.
I have been frustated trying to find those links knowing I had been there in the past.
Saved to Fave file as of now! LOL
The earthquake produced a tsunami that was recorded at several tide gages (operated by NOAA/National Ocean Survey, the Pacific Tsunami Warning Center, the University of Hawaii, and the Japanese Meteorological Agency)."
Here is a chart with measurements taken in Port Orford, Oregon regarding the Tsunami in November 2003:
Strat when you live on a coastal area literally and you are in "the quake" you don't ponder if it was a 7+ and when your town doesn't do well in getting info out to the community and USGS takes lately longer to post the whereabouts and magnitude you simply decide wether to get your family into tsunami evac mode.
An aquaintance works for a guy who is a volenteer fireman and he evacuated his whole business and went to higher ground untill he got word of how and where the quake was.
I have to load my adult son into a wheechair which takes time esp if he is excited and load into the van the lift goes at it's own pace.
I called 911 in the Oregon quake and she said to leave my scanner on that she would announce evac or not and she did withen 10 min. so I did not load him up.
So see after one can go thank God it was not a biggee, but during you make plans as if it was.
My friend who lives half a mile down the road has decided we have the best road to go up for safe ground and if it was a huge disaster there is a trail that leads from the top of our hill over to Toledo inland it maybe a 8 miles hike but it has been done by bad guys out running the cops once.
I wonder if that is the one everyone was talking about with all the chit chat stories around town.
I vaguely remember but thought it was years ago we had a 7 or 15 inch increase by the time it hit our shores can't remember for sure.
New Zealand has been hit four times in 20hrs. Unfortunetly a woman Mrs. Robinson was killed. Many other had home damage bad enough to leave and others were injured by falling trees.
Boy the earth is burping. Hope it doesn't pass gas aka volcanoes too.

I can see Vancouver Island from my kitchen window. Didn't feel a thing.
Here's a 3.7 just now 100 miles from Valdez. Noticeable, but not large.

Thank you.
You may already have this yahoo earthquaked link thought I would share just the same.
Either my tin foil hat is cutting off blood flow to the brain or there is some freakay shaking goin' on.
The one we had today is at least in a expected zone and 200 mi. out. it's these ones near land here and up in BC that have the scientist puzzled in turn are making me walk around the house going "freakay". Everyone is telling me to shut up about the earthquakes already.
Here the yahoo link

Oh and one of my dogs 10yr old Kolbe is sticking to me like glue which is normal when he is freaked but nothing in that catagory except the massage therapist visiting yesterday.
Your big one was just like ours on the Oregon Coast in that it swayed S to N.
Wonder how the volcanoe activity is doing up here in the PNW.
Earthquakes occuring as they have in your area would rattle anyone's nerves. IMHO you are feeling and acting quite normal for the circumstances.
Also remember life in California - how many folks dash to the grocery store for batteries and water after a quake.
Cats and dogs can supposedly smell radon gas and they can hear higher and lower sound frequencies than humans, all of which occur before a large quake. Your dog is also trying to protect you by staying close, in case you get lost. :-)
A couple of strange things I've noticed before a large quake: A very large dark brown spider suddenly crawled out of an electric wall outlet and scurried up the wall. The earthquake happened about an hour later.
One night I was awakened by the sounds of my cat howling loudly while she was digging a hole to China in the litter box. She emptied all of the kitty litter out of the box. I swept up the still clean litter off the floor and returned it to the box and then went back to bed.
The cat then dug and kicked every bit of the litter out again onto the floor, meowing in protest.
Again, I got up, swept up all the kitty litter off the floor and put it into the box again, but stood there watching the cat.
Cat didn't seem to care that I was watching and again started digging and kicking all of kitty litter out of the box. I decided it better to allow the cat an empty litter box than to lose any more sleep.
A big earthquake shook hard just as I was falling back to sleep.
Earthquakes are natural occurrences, they are as natural as the sun rising in the East and setting in the West. The best we can do is make sure everything inside our home is tied down and that we are prepared.
Also, looking at the following site has helped me get perspective on just how often there are earthquakes all over the world.
Magnitude Greater Than 2.5 Earthquakes From Around the World
For example, there was a 3.3 earthquake occurring at 7:17 a.m. on July 16, 2004 4 miles from Riverton, Iowa.
Magnitude 3.3 - IOWA 2004 July 16 12:17:30 UTC
There was a 2.0 earthquake about 86 miles from Memphis Tennessee on Monday at 3:53 a.m.
Magnitude 2.0 - TENNESSEE 2004 July 19 08:53:37 UTC.
A 3.0 quake hit 4 miles from Summerville, South Carolina yesterday (Tuesday) morning at 5:13 a.m.
That quake sent shock waves around the world in less than a minute. Show the map to people who have told you "enough already about earthquakes."
Where do u think this big megathrust earthquake going to happen? I hered it's going to happen west of vancouver island like where Tofino is. Others have said right near Victoria/Seattle. It's kinda scarey when you think about it! What would happen if your on the Bc Ferry's or the Anacordis and this happened? even if the earthquake was west near tofino? Other people say there is no lock on the plates and that there well lubricated and moving smootley. Anyways, do u think it's going to happen soon or like in another 100 years?..
July 22 - The ETS event predicted for spring/summer 2004 continues. Tremor began on July 8 and slip has been confirmed by GPS observations. The event started beneath the northern Olympic Peninsula in Washington State and has now migrated northwest to the region of Cowichan Lake on Vancouver Island.
July 22 - update: Aftershocks continue - but are becoming much smaller and less frequent.
July 19 1:01am PDT (08:01UT): A M=6.4 earthquake occurred off the west coast of Vancouver Island, 40 km to the southwest of Nootka Island. It was felt at communities across Vancouver Island, including Port Alice, Port McNeill, Alert Bay, Campbell River, Courtenay, Comox, Duncan, Nanaimo, and Victoria. On the BC mainland, it was felt at Whistler, the Sunshine Coast (Gibsons, Sechelt and Powell River) and across Greater Vancouver. Other than some items being knocked from shelves, there have been no reports of damage.
July 16 12:27pm PDT (19:27UT): A magnitude 4.5 earthquake occurred 97 km NW of Dawson City, Yukon. It was felt in Dawson City. Click here for map.
July 15 05:06am PDT (12:06UT): A magnitude 5.8 earthquake occurred 40 km west off Nootka Island, just off the west coast of Vancouver Island. It was felt by residents on northern and central Vancouver Island, the Sunshine Coast and by a few in greater Vancouver and the Lower Mainland. The largest aftershock was M=3.6 at 06:55 PDT July 15.

Episodic tremor and slip is a new phenomenon discovered in the Cascadia subduction zone beneath Vancouver Island by scientists with the Geological Survey of Canada (GSC) . It consists of repeated slow slip events on the lower portion of the subduction fault, accompanied by unique non-earthquake tremor-like seismic signals that emanate from the same region.
Large subduction earthquakes of magnitude about 9 have occurred on the Cascadia subduction zone beneath the west coast of Canada and the United States on average every 500 years or so, but with considerable variability in repeat times. The last one was on January 26, 1700.
All along this margin, continuous Global Position System (GPS) installations show a slow landward movement towards the northeast, demonstrating long term stress accumulation leading up to the next great Cascadia earthquake.
A team of scientists at (GSC) has discovered that GPS sites in the southern Vancouver Island region occasionally reverse their motion, moving seaward for periods of about two weeks before resuming their longer-term landward motion.
