Hawaii orders evacuations in tsunami threat; Japan Death toll rises to 32 (http://mb.com.ph/articles/308832/hawaii-orders-evacuations-tsunami-threat)

Hawaii ordered evacuations from coastal areas due to the threat of a tidal wave set off by Friday's earthquake in Japan as a tsunami warning was extended to the whole of the Pacific basin, except mainland United States and Canada...The International Federation of Red Cross and Red Crescent Societies warned that the tsunami is currently higher than some Pacific islands which it could wash over.

And another one at http://www.foxnews.com/world/2011/03/11/massive-7-magnitude-earthquake-strikes-japan/ with quote:


Japan lies on the "Ring of Fire" -- an arc of earthquake and volcanic zones stretching around the Pacific where about 90 percent of the world's quakes occur, including the one that triggered the Dec. 26, 2004, Indian Ocean tsunami that killed an estimated 230,000 people in 12 nations.

I remember seeing a documentary several months ago showing the bottom of the ocean floor with gigantic wall, either the floor sunk or the wall went up. It was so huge and steep, quite impressive.

Can't wait to see the documentary for today's quake, quite fascinating how dramatic the crust can shift in an instant.

...As an 8.9-magnitude earthquake struck Japan's northeastern coast Friday, the world's first early warning systemódeveloped by the country's meteorological agencyódetected the quake's shockwave near the seismic center and sent off the warning message, which appeared on national television and radio as well as mobile phone screens...

"...anyone know how much warning their new early warning system gave them?"

"... The window of time from the announcement of an Earthquake Early Warning until the arrival of the main tremors is very short, i.e. a matter of seconds (or between several seconds and a few tens of seconds). In areas that are close to the focus of the earthquake, the warning may not be transmitted before strong tremors hit..." (http://www.jma.go.jp/jma/en/Activities/eew3.html)


"...the system is designed to send out the warning only if the intensity of the quake is lower 5 or stronger on the Japanese scale. (The scale has three levels for each number, so there's lower 5, 5 and upper 5.) Friday's quake was 7 on that scale, and the system sent out the warning message 8.6 seconds after it detected the very first shock wave."

Just a few things just reported within the last couple of minutes....

The nuclear power plants appear to be safe. There is concern for one where refrigerant didn't disperse as expected and they've evacuated the town as a precaution. BBC says that they are the most modern and well-maintained plants in the world. Sensors for quakes apparently worked as expected shutting down plants and triggering safety measures in less than one second. They are the most sensitive sensors known to man. A train derail almost ten miles from a plant shut it down immediately a couple of years ago. Fascinating.

This is a disaster of epic proportions. They just said pilots reported seeing around 1800 homes being swept away under a fast rushing wall of water; no way to get a grip on casualties because of the devastation.

Sixth largest earthquake in recorded history of the Earth. Eight thousand times more energy than the one that hit New Zealand recently.

So some interesting details coming out from the aftermath of the massive quake.

The Earth's rotation axis was shifted by 25 centimeters from the event. What does this mean? Nothing right now. The changes are extremely minute for and will eventually cause for the removal of a single second from a day centuries down the road (it will be accumulating by the millionth of a second per year). The other impacts these events have is changing amount of sun a location gets and the speed of the Earth's rotation. However, all very small amounts that we won't notice. The 8.8 Chile earthquake did something similar.

The other change, the main island of Japan moved roughly 8 feet from this quake.

So far it looks like over 200 aftershocks have taken place with many still 5.0 or higher.

*grabs tinfoil hat* ... So that has been Chile, New Zealand, and now Japan around the ring of fire. Seems to be one main area missing from that without a major quake.

Pretty much. Anywhere from Alaska through Mexico hasn't had a major quake for some time. Just seemed interesting how the major quakes are working their way around the ring. Not saying it is likely to happen, but there are plenty of studies suggesting the west coast faults have pressure building up.


Fortunately for Yelllowstone, when it blows not very many people live around it.

When that thing blows, I don't think it will matter if you live by it or not. :) The amount of ash that would be put in the air would have us in a nuclear winter for at least a decade.

What would that be like - what temperatures do they think that would put the world at? I realize the sunlight and temperatures needed for crops would be vastly diminished and people living on the edge would be toast. What percentage of the world's population would likely survive, and where? What is the speculation?

Based on the studies done and comparisons to the previous large caldera eruption about 74,000 years ago from the volcano Toba (in Sumatra)...not all that pretty. The previous Yellowstone eruptions have left a blanket of about 3 feet of ash on every location roughly west of Mississippi. Oklahoma itself has been impacted by significant ash hall in the eruptions 630,000 and 2 million years ago. Both eruptions ejected anywhere from 1000 to 2500 cubic kilometers of ash and debris. Temperature impacts are a bit less certain from those eruptions. The Toba eruption ended up cooling the northern hemisphere by 21 degrees and darkened the sky around the entire planet. A study from NYU put the estimate at 75% of all planet life was eliminated in that, and a major impact to animal species. Impacts to human/animal species would be greatest with in 600-800 miles of the volcano where the estimate is a 90% fatality rate. Then that can increase further out with the spread of the ash cloud and sulphuric acid aerosols that will go with it.

Essentially...not a pretty picture if we ever would have to go through something like that. Pretty much game over and time for Earth to do a reboot.

The Yellowstone Caldera has erupted several times in the geologic record. It's pretty rough on the life in Nor Maerics but I wouldn't call it a reboot of the whole planet. They are barely blips in the atmospheric and temperature record. They'd be awful for us, to be sure, but their influence is geologically and biologically very short. You can see their influence, but it doesn't deviate the orbital-driven temperature trends.

The ice core graphs are neat to look at, but a bit out of context here. The last time the Caldera erupted was well over 600,000 years ago...which would give you only one event on this graph. So the graph really isn't all that useful here. Especially considering the short term (6-10 years) impacts it would have. I think you also need to look at the comment in the context of my post. Previous eruptions eliminated an estimate 75% of all plant life in the northern hemisphere. That is about as close to a reboot of the world we know as we'll have outside something more catastrophic.

Any who, back on topic some.

What direction each side going along there? I was thinking if the crust portion going up toward western direction, does that pull the entire tectonic plate further away from California?

Toba is in that range, as are many other eruptions as large or larger than Yellowstone. And our current extinction rate is orders of magnitude larger than any of those.

I'm certainly no expert, but from what I keep hearing, the most dangerous area for the US is the Cascadia fault off the coast of Washington and Oregon which could cause a huge tsunami. There is apparently little danger of that from fault lines in California which are inland instead of off the coast.

All the plates are in a complete state of flux. The quake off the coast of Japan released pressure in some areas while potentially raising pressure in other others. Plates are never balanced because they are always moving, slowly.

I agree more with Venture. Sorry, but, your Toba is never featured on the Mega Disasters show on the Discovery Channel. It's always Yellowstone, which blows majorly, cause if it goes...we'll be known as the United States of Ashtray. And I will shoot myself if I don't die from suffocation or a firey rock crashing down on top of me cause I'm pretty sure it will be able to send a projectile that far. I'd rather die from a gunshot wound than starvation because 90% of all living creatures dies here.

03-17-2011, 12:55 AM
Some interesting stuff going around now.One is a raising concern in Japan of the events the earthquake may have triggered. Right after the earthquake, a smaller fairly active volcano erupted after being quiet for a few weeks. The biggest concern though is a 6.2 shallow quake under Mount Fuji a couple nights ago. Fuji hasn't erupted for over 300 years and some fears now that it could get a rude awakening. So far there haven't been any other earthquakes in that area from what I've seen on the USGS site. Normally there would be a nice swarm develop signaling the rise of magma, but doesn't appear to be going on yet.

http://www.seisvol.kishou.go.jp/tokyo/eng/314/314_pic.jpg

A Fuji eruption definitely would not be a good thing right now, and depending on the amount of ash it would eject could make the US experience what Europe did last night.

There is also a story going around now, thanks to the whole supermoon hysteria, about the increasing risk of a quake somewhere on the west coast. Granted if you look at the pattern it does seem to be going clockwise around the ring of fire, but we'll see. There is bound to be a major earthquake out there in the next 10-20 years. Just about every scientist would stand by that prediction. Now if it happens in the next couple weeks, who knows. I would be interested to see what the thinking is if a major earthquake out there would happen, what the impact would be on either the Cascade Volcanoes or those throughout California/Arizona. The Long Valley Caldera in Central California has been in a consistent period of uplift with a fairly (geologically) recent lava dome since having a major swarm in the 80s with magnitude 6 quakes. It however is not like Yellowstone and doesn't sit on a hotspot.

Just some ramblings. If anything, the ever changing planet is interesting to watch on how it is constantly reshaping itself.

Here is a clip about the potential for a west coast earthquake: http://www.foxnews.com/on-air/hannity/transcript/america-overdue-catastrophic-earthquake

Don't make me slap you. >_<

We are so not prepared for this.

I agree more with Venture. Sorry, but, your Toba is never featured on the Mega Disasters show on the Discovery Channel. It's always Yellowstone, which blows majorly, cause if it goes...we'll be known as the United States of Ashtray. And I will shoot myself if I don't die from suffocation or a firey rock crashing down on top of me cause I'm pretty sure it will be able to send a projectile that far. I'd rather die from a gunshot wound than starvation because 90% of all living creatures dies here.
Is that the new standard for reality? "Has a feature on the Discovery Channel" = true? Look them up, their sizes are very comparable. We know with great detail what a disaster like this would do to us and our current path on atmospheric tinkering is actually a much larger disaster, it's just slower so we don't worry about it.

I was watching Predicting Monster Earthquakes on the Discovery Science channel (filmed sometime after the major quake in Haiti, '08-'09) and there was several repeated mentions that scientists do not know what causes earthquakes.

....... DUH?! Of course we all know what causes earthquakes. :-/

Anyone know how long it typically take for new documentaries to come out about our recent earthquakes?

We know what causes them, it's identifying the trigger moments that is proving elusive.
