1. 1700/01/26 - 9.0 Cascadia subduction zone, British Columbia.
2. 1949/08/22 - 8.1 Offshore Queen Charlotte Islands, British Columbia.

ontariolightning: Earthquake 7.7
Aftershocks 5.8, 4.8, 5.1, 4.6, 4.7, 4.5, 4.5 5.0

3 times (in bold) that an aftershock was greater than the one before it.

Does that signify this as a foreshock?


Aftershocks don't neatly decrease in intensity over time. The quick-and-dirty rule is that there will likely be at least one aftershock with a magnitude one less than the main shock...so expect at least a mid-6 aftershock at some point, along with thousands of smaller ones.

At least for California quakes, seismologists generally cite about a 5% chance that any given quake is actually a foreshock. There's a slight chance that the 7.7 quake was itself a foreshock, but that has nothing to do with the aftershock sequence. Fore- and aftershocks, if large enough, generate their own fore- and aftershocks, and there is no way to tell which is the main shock until a bigger quake either happens or doesn't.

Gene Masseth Jr.: Ok, I don't understand waves and stuff: I read a Yahoo story that said a 4 inch wave hit Southern Alaska and that it's the start of the tsunami stuff.

4 inches? That's it? Aren't most waves in the ocean like a foot high when they crash? I'm not getting why this is a big deal...



Tsunamis come in trains of up to a dozen separate waves over a period of hours. The first wave may not be the biggest. Also, the height of a landfalling tsunami can vary greatly from place to place depending on local offshore topography, currents, etc.

Since a measurable tsunami has been observed, a tsunami warning has been issued. Once more information on actual wave heights is available, the warning may be modified or discontinued.

Wrong fault. Way, way, way wrong fault.

You probably meant Seattle, Vancouver and Portland.

Oops, sorry. Yeah. I was thinking about the last earthquake thread, or was it a SF thread.
They're both overdue for earthquakes.
The SF one is just going to be far worse

Very unlikely. SF isn't capable of over a 7.5 or so. The CSD is capable of a 9.0, and most of the PNW is built on fill and seismically decades behind SF.

PDX didn't even know they could face a major quake until 1990, so they have a lot more buildings that are deathtraps than SF. Seattle's downtown is built on fill that will return to the Sound. The tsunami the rip 9 creates will kill thousands on the OR/WA coast as well.

CA quakes are nothing compared to The Big One the PNW is facing and overdue for.

If Cascadia goes, all of the news shows will say something like "The Pacific Northwest just fell into the ocean. And now let's turn to Brad, with more news on Hurricane Sandy."

Just FYI those islands have been inhabited for thousands of years, and the Haida had a rich culture until the European explorers showed up in 1774 offering the usual trade of smallpox and religious indoctrination in exchange for plundering the natural resources.

Canada's biggest quake was along the same fault in roughly the same area..


From Natural Resources Canada..
----

The M8.1 Haida Gwaii (formerly Queen Charlotte Islands) Earthquake of August 22, 1949


Local Date and Time: August 21, 1949 at 08:01:12 pm Pacific time
UT Date and Time: 1949-08-22 04:01:12 UT
Magnitude: MW 8.1; MS 8.1
Maximum Intensity: (Modified Mercalli) VII-VIII
Latitude: 53.62° N
Longitude: 133.27° W

Canada's largest earthquake (magnitude 8.1) since 1700, occurred on August 22, 1949 off the coast of BC. It occurred on the Queen Charlotte Fault (Canada's equivalent of the San Andreas Fault) - the boundary between the Pacific and North American plates that runs underwater along the west coast of the Haida Gwaii (formerly Queen Charlotte Islands) off the west coast of British Columbia. The shaking was so severe on the Haida Gwaii that cows were knocked off their feet, and a geologist with the Geological Survey of Canada working on the north end of Graham Island could not stand up. Chimneys toppled, and an oil tank at Cumshewa Inlet collapsed. In Terrace, on the adjacent mainland, cars were bounced around, and standing on the street was described as "like being on the heaving deck of a ship at sea". In Prince Rupert, windows were shattered and buildings swayed.

Things could be worse: this could only be a foreshock for the next Cascadia Earthquake. If you recall, two days before Japan's 9.0, on March 9, there was a 7.2 about 25 miles from the March 11 epicenter. That's a bit of an extreme example, though; the 2004 earthquake which caused the Indian Ocean tsunami was preceded by a 7.3 foreshock in 2002. Foreshocks can cause enough stress on subduction zones that they eventually cause the plate boundary to basically unzip.

I can understand that. However, in California, things are built to code to survive earthquakes. Many places in the US don't have that. Additionally, many places have buildings a hundred or two hundred years old. Which tend to be made of old masonry and stone that doesn't weather earthquakes well. We had a tiny quake up here in PA a couple years back, and we had old brick structures in a number of places take some pretty bad damage. A falling brick or stone block doesn't care about numbers much, when it's busy moving your skull outta the way.

Should be fine here in Anchorage. It's actually very difficult for Anchorage to get hit with a tsunami. The quake would have to throw a Luke Skywalker Death Star shot straight up the Cook Inlet at high tide. Even the '64 quake didn't hit Anchorage with a tsunami, there's just not enough open water to move there.

IIRC the measurements they give aren't the total wave size, they're how much bigger the wave is than a normal wave under the normal tidal condition at that time at that location. For example, Langara Island has reported a couple of 44-50cm (18 inch-ish) waves, so if their waves were normally a foot high at this time of night when they crash, these ones were two and a half feet.

The only Cascadia quake in human-recorded history is the 1700 event. Geological and paleobotanical records suggest a frequency of every 300-600 years for Cascadia megaquakes. What we don't have are any detailed records of foreshock sequences or other subtle clues as to whether or not the big one is really on its way based on this one particular quake.

No word yet on the size of the tsunami expected for Hawaii. There are some readings provided in the warning text below, but they're deep water readings, and I don't know their relative magnitude (e.g., whether they're impressively high or not).

The most relevant part of the warning text:
BULLETIN
TSUNAMI MESSAGE NUMBER 3
NWS PACIFIC TSUNAMI WARNING CENTER EWA BEACH HI
709 PM HST SAT OCT 27 2012

TO - CIVIL DEFENSE IN THE STATE OF HAWAII

SUBJECT - TSUNAMI WARNING

A TSUNAMI WARNING IS ISSUED FOR THE STATE OF HAWAII EFFECTIVE AT
0709 PM HST. THIS UPGRADE IS DUE TO THE SEA LEVEL READINGS
RECEIVED AND THE RESULTING CHANGE IN THE HAWAII TSUNAMI
FORECAST.

AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS

ORIGIN TIME - 0504 PM HST 27 OCT 2012
COORDINATES - 52.8 NORTH 131.8 WEST
LOCATION - QUEEN CHARLOTTE ISLANDS REGION
MAGNITUDE - 7.7 MOMENT

...

EVALUATION

A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG
COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION
SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.

A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE
CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD
COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE
INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS
CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST.
TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT
RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI
WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL
QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE
CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED
BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH
TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.

THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1028 PM HST SAT 27 OCT 2012

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

Pfft it's loading for you?

No, but I'm not getting any error messages either. It is part of the NOAA, so I guess combined with the Hurricane Sandy there's quite a lot of traffic

God-is-a-Taco: davidphogan: God-is-a-Taco: Hmmm yep, that faultline continues its activity as expected.
San Fransisco still unlikely to exist in 10 years.

Wrong fault. Way, way, way wrong fault.

You probably meant Seattle, Vancouver and Portland.

Oops, sorry. Yeah. I was thinking about the last earthquake thread, or was it a SF thread.
They're both overdue for earthquakes.
The SF one is just going to be far worse


Very unlikely. SF isn't capable of over a 7.5 or so. The CSD is capable of a 9.0, and most of the PNW is built on fill and seismically decades behind SF.

PDX didn't even know they could face a major quake until 1990, so they have a lot more buildings that are deathtraps than SF. Seattle's downtown is built on fill that will return to the Sound. The tsunami the rip 9 creates will kill thousands on the OR/WA coast as well.

CA quakes are nothing compared to The Big One the PNW is facing and overdue for.

eraser8: I've met rude Canadians.

Of course, they were French Canadians.


And by their own reckoning, they aren't Canadian.

True story: after dating my wife for a bit, we went to meet the parents. After about 30 words spoken to the future mother in law, she says, apropos of apparently nothing, "I've taught my daughters that they should leave anyone who beats them." I said something to the effect that I usually wait a few months before starting the beatings. Future father in law laughed. Next summer the FIL and I are going on a whiskey tour of Scotland.

Nother one: Mrs Wawa and I had been dating for near a year. Future MIL says, "I've found any man under the age of 30 is just looking for sex from a woman." I replied, "I'm 28." She says, "I know." I'd lost a step at the time, I think. Should've asked about how old she was when she was dating Mrs. Wawa's dad.

shower_in_my_socks: A small tsunami has been recorded, but according to some tsunami expert on Twitter, "a widespread destructive tsunami threat does not exist based on historical data." CNN saying that the earthquake was in shallow water, so the tsunami shouldn't be very big.


I wonder about the other side of the Pacific. The 1700 rip 9 on the Cascadia Subduction Zone was only definitively proven to exist due to the damage recorded from it in Japan. I know a 7.7 isn't a 9.0, but...

eraser8: Honestly, that's pretty big.

I could feel 5's when I lived in California...and a 7 is, what, 100 times bigger?


The magnitudes being talked about are based on the log10 scale. As such, a 7.7 is ~500 times as strong as a 5.0 (10^(7.7-5) ~ 501). According to Wiki, in terms of energy release, it's 22 petajoules vs. 2.2 terajoules; in other words, ~10,000 times as much energy is released in a 7.7 than a 5.0.

MaudlinMutantMollusk: Aaaaaannnnndddddd HAARP gets fired up for the big October Surprise

/Perfect Storm?

If HAARP were to be used to create an October Surprisequake it would seem that New Madrid would be a better ROI than wasting remote islands in Canada. Though that 3.5 in western MT earlier this evening was odd.

whammawhamma: Tsunami warning up for West coast US/Canada and Alaska now.



FTA: Tsunami Warning for AK, British Columbia, US East Coast and US West Coast

LOLWUT? Are they talking about the south/east coast of Alaska?

Worth noting that the tsunami warning is serious enough that one has supposedly been "observed."

She shows up in all threads. That's the way things are now. Get used to it.

Exactly. The Egyptians had their pyramids. The Romans had their Colosseum. You Americans have Honey Boo Boo.

RollingThunder: Rusty Shackleford: My takeaway from this: pretty much no-one outside of British Columbia calls the islands Haida Gwaii.

Nobody in BC calls it that, either.


Probably just us in gumment, then; especially since we work with the First Nations to manage Gwaii Haanas, and are used to saying it.

bronyaur1: How far is this from Vancouver?


about 700km/500mi NNW. The islands are 100km or so from the coast.

And this is an excellent occasion to let people know that the islands are called Haida Gwaii now (or still, or again, depending on your perspective).
