Great Japan quake generates 8-foot tsunami in California

A great earthquake rocked the coast of Japan at 5:46 GMT on March 11, generating a dangerous tsunami that raced across the Pacific. The mighty earthquake was rated 8.9 on the Richter scale, making it the 7th most powerful tremor in world history. The world's 8th largest earthquake, a magnitude 8.8 event, hit Chile on February 27, 2010; never before have two top-ten earthquakes hit so close together in time. Today's quake was the strongest in Japanese history, and will likely be the most expensive natural disaster in world history, surpassing the $133+ billion dollar price tag from Hurricane Katrina.


Figure 1. Model-computed energy from the March 11, 2011 tsunami as visualized by the NOAA Visualization Lab.

In the U.S., the highest tsunami waves from the earthquake hit northern California and southern Oregon, with a wave height of 8.1 feet observed at Crescent City, CA, 8.6 feet at Port San Luis, CA, 8.7 feet at Arena Cove, CA, and 6.1 feet at Port Orford, OR. The tsunami swept four photographers out to sea in the Crescent City harbor, injuring three of them and leaving one missing. Extensive damage was done to the harbor and 35 boats. Up to $2 million in damage also occurred in the Santa Cruz harbor south of San Francisco.


Figure 2. Tide gauge at Crescent City, CA during the March 11, 2011 tsunami. The green line shows the height of the tsunami wave; the red line shows the observed water level. The highest tsunami wave came at at 17 UTC (9am PST), an hour and 10 minutes after the initial wave, and was 7 feet high. Image credit: NOAA.

Crescent City was hit by a devastating tsunami after the March 28, 1964 magnitude 8.8 earthquake in Alaska, which killed ten people in the city and destroyed much of the business district. The city is fortunate today that the tsunami hit at low tide, or else water levels would have been five feet higher in the city during the wave. The tide gauge at Crescent City, CA (Figure 2) shows that at least 18 separate tsunami waves have hit the harbor as of 2:45pm PST. The first wave came at about 15:50 UTC (7:50am PST), was about 2.5 feet high, and was not preceded by the ocean falling and water being sucked out to sea. After this initial wave, the ocean level dropped rapidly by 8 feet, and then a series of large waves began rushing in and out, with up to a 13 foot difference between low water and high water. The rapid speed of the in-rushing and outflowing waves were what did the damage to the harbor and its boats. The largest wave came at 17 UTC (9am PST), an hour and 10 minutes after the initial wave, and was 8.1 feet high. Fortunately, this wave came near the time of low tide, and the wave was only 2 feet above last night's high tide mark. Tidal range between low and high tide is about 5 feet at Crescent City. The tide is now rising, and new tsunami waves with height of 3 - 4 feet are still rushing in and out, with the one just before 21 UTC (1pm PST) reaching a height about 2 feet above high tide.

Portlight.org is mobilizing to provide financial assistance to people with disabilities affected by the disaster, and there will undoubtedly be a huge relief effort by numerous charities in the wake of the earthquake. Your financial contributions and prayers for those affected will be valuable.

Waves (Feather3)
During our tsunami warning that had been downgraded to an advisory, this afternoon. It was getting closer to high tide, but it was strange, watching the surges: one minute, the beach was bare, and within minutes, a surge would build up as wave after wave, low, but surging, would inundate the beaches....more shots to come.

In this other view of the 2nd explosion.

Notice there is sound and you can hear various detonations (seems like 3 det.).... There is also a fireball, different from the 1rst. blast...

According to Michio Kaku, PhD stated on GMA that there are reports that reactor #3 MAY HAVE suffed a 90% uncovering of its core. Also they showed a very clear satelite photo, courtesy: Digital Globe of the reactor building after the explosion. There is a decent white plume emitting from that building. Do not know how long after the explosion it was taken.

1224: A quick summary of the nuclear crisis in Japan: The nuclear emergency following Friday's earthquake and tsunami has worsened, with the operators of the damaged Fukushima nuclear plant warning that they can't rule out a possible meltdown. The company says it's possible that cooling water at the number two reactor has evaporated, exposing the nuclear fuel rods. The BBC environment correspondent Richard Black says such an outcome would be very serious

My original point was that potassium iodide cannot be taken on a chronic basis. Perhaps some of those preparations are made with sodium iodide - if so, they may work.

In any event, I'm sure there are lots and lots of potassium iodide pills in Japan.


Edit: the fact that potassium iodide is added to salt (sodium iodide) strongly suggests that sodium iodide does not offer protection against goiter. It's potassium iodide that confers the protection ... and potassium iodide cannot be taken chronically. Catch-22 if you have a radioactive plume that involves controlled or uncontrolled release that takes place over a period measured in months. You can't take potassium iodide chronically (no matter what you get it from) and sodium iodide doesn't offer the thyroid protection from I-131.

That "one month in one hour" business means that they were exposed to radiation that was approximately 730 times background. Good thing they didn't stay too long.

I just got this from the BBC live news side links.

1125: Worrying news, this: The operators of the damaged Fukushima nuclear plant say it's possible that cooling water at one of the reactors has evaporated, Reuters reports. The company says it can't rule out the possibility that the nuclear fuel rods in Number 2 reactor were now exposed and could be at risk of meltdown

Says it comes from Reuters so if anybody has a link to that there may be more to the story.

Things look really bad over there and I can't see how they can easily be working in the debris that must be all over the place after the first 2 explosions, they might not even have much power over there after all the chaos as well and its getting dark about now.

I suspect salt intake will go up, but I think it would be hard to get protective amounts on board that way. The very small amount of potassium iodide in salt is intended to address iodine deficiency associated with thyroid disorders (it is protective against goiter).

0943: "Some of the nuclear fuel may have partially melted down in the overheating," adds our correspondent. "But crucially the primary steel nuclear containment vessels are said to be intact. The authorities report no significant radiation leak, although some Japanese people may be disinclined to trust the authorities who have lied to them about previous nuclear accidents. It looks at the moment as though catastrophe may well be avoided, but the crisis is far from over.

No kidding.

In looking at some detailed reactor cutaways and diagrams, it's obvious that at least two of the three layers of containment are gone on both units #1 and #3. Even if the pressure vessels are still intact--as is claimed--there's likely no way to keep that vessel submerged and cooled.

BBC and CNN say the cooling has failed in units #2 and #4, with #2 being the more critical of the two.

That, sadly, is exactly what I was thinking. RPV, secondary containment, reactor building.

Edit: and just enough time between explosions for overpressure to rapidly build and propagate through the outer two layers.


Wouldn't the explosions have to be outside in in order to generate three sounds? If it was inside exploding, the sound wouldn't pass through the outer walls and then cause the explosion, the sound would be the explosion?

Either way, this sucks.

If Skye's earlier post is correct, the sailors on the deck of the Reagan got quite a bit more than a chest x-ray passing through a cloud of radiation. This did not make it into the official release from the Pentagon, but it may well be correct.

This new explosion is a totally different type of thing from the first on.

If you look at it slowly then you first see a big orange flame from the right side of the building then the big plume of smoke rises very rapidly and after a few seconds there is visual evidence that a large object or possibly 2 are falling on the left side of the picture from a considerable height and its falling fast so its probably not 'cladding off the building'

According to the 'experts' on the live BBC the reactor contains about 80 tons of high energy fuel. There's a lot of steam type vapour about and a quite strong wind.

I'm just wondering what kind of massive intervention that the US could do that Japan can't. Other than lend a few helicopters for search&rescue and for emergency food&water deliveries...

Missed that news item entirely? Sounds interesting, do you have a link to an article?

Speaking of which... NHK reported that a large section of eastern Honshu(Japan) nearest the epicenter has subsided ~0.7metres (a bit less than 2feet4inches).


I'm sorry but I don't have a link. I was watching NHK. They spoke of a firefighting (I think) helicopter that had spotted a 3m Tsunami at sea headed for Honshu. There were simultaneous reports of a 5m change in sea level (I presume apparent sea level). The tsunami never arrived, although warnings were sounded and evacuation encouraged.

Strange ...

edit: and on intervention, I was thinking more in terms of the currency and futures markets. The Japanese central bank has been busy, but I am fairly sure they are not acting alone:

Wondering about what kind of massive intervention that the US could do that Japan can't or won't.
Other than lend a few helicopters for search&rescue and for emergency food&water deliveries...

Missed that news item entirely. Sounds interesting, do you have a link to an article?

Speaking of which... NHK reported that a large section of eastern Honshu(Japan) nearest the epicenter has subsided ~0.7metres (a bit less than 2feet4inches).

Quoting WatchingThisOne:
A rather somber update at the New York Times:

update on Fukushira nuclear difficulties

The second page is particularly discouraging. They were using FIRE HOSES to get seawater into the containment structure before it blew, if it blew. That seems a poor way to establish circulation through a hot reactor core ("One American official likened the process to 'trying to pour water into an inflated balloon'") ... and any water remaining in the base of the containment structure would not be a happy thing to have around if the corium decides to drop.


Which begs the question of what are they doing NOW if they lost the containment structure?
