Earthquake in Japan....9.0...ouch!

Looks like everyone's queueing up for a go on the swings
People lining up for food/water in Japan
Now thats what I call organised..... Who recalls what what the lines looked like in Haiti?

Of course, this sort of information gets glossed over and sandwiched between paragraphs of panic and scaremongering.

It is when the design presentation of the builds stated that quakes above 7.9 would not occur in the fault zone seems to be the biggest problem. The risk assessment has not reflected what has happened on the site of the power plants. The fact they have withstood so much and the Tsunami.... We dont know which caused the most damage yet.....
I'm not sure about the newer reactors but the older ones that they are having problem with were engineered for a PGA of 0.125 IIRC which is roughly equivalent to what you'd expect from above a Magnitude 7 quake at a depth of upto 10km - which even in that part of the world is a pretty high level to work towards.
During the original quake they measured PGA at almost 0.35 in the vicinity of Fukushima No. 1 (this is more than 90km from the epicenter) its a miracle things haven't turned out much worse.
A major difference is that the Fukushima reactors have a hard reinforced concrete containment vessel around the reactor and Chernobyl didn't. Then you can look at things like they're different designs that use different moderators, which is important should the core be exposed to the atmosphere.
If an 8.9 magnitude quake occurred at a shallow level under London I very much doubt there would be many buildings still standing for almost 300 miles - the amount of energy in that quake was 300,000 greater than the biggest inland quake in the UK and around 4000 greater than the biggest ever recorded in the British Isles.
BBC News would be asking why the government hadn't seen the earthquake coming.
Now I'm very upset!
Which bit makes you sad? Most of the companies have factories in Europe, or is it the fact the article uses the word "access" when it should be "assess"??
but what is the half-life of the radiation?
as far as i understand its around 15 secs, so unless your in the area of the reactor, there is no real risk. ie in the gas that is being released is Nitrogen-16, so within a few mins its just steam
Depends whats released into the atmosphere (or groundwater) theres a whole raft of potential toxins/heavy metals that potentially could be released.

Errm, I don't know, hence asking? As I've said several times now, I've not seen any of the press conferences from Tepco, or any of the Japanese guys say whats happening.
If you're trying to be sarcastic, yes, water turns into steam, and then, the condensor isn't working because the pumps aren't working, so theres just too much heat and no way to bring it back down. So they pump in more water, and more and more, but eventually that would leave you with ever increasing levels of steam, increasing pressure, and a more dangerous situation.
I've not seen any of the official statements cover two key things, how they are managing steam/gas/pressure levels in the core as they add water nor, even more importantly, whats going on with the actual pumps that should have been working. Are they just done, no way to fix them, or are they actively fixing them as fast as possible.

It's the same for most business' there though, whether directly affected by the Earthquake/Tsunami or not.
My Father works for a very big IT firm and forwarded me an e-mail from his team in Tokyo this morning.
- Hundreds of their employees are unaccounted for... this may be in part just due to lack of communications available.
- Parts of Tokyo still don't have power and the government has asked people not to travel, for one because of safety with most road signals out and for business' to save electricity by no operating.
- Many people can't even get to work because there are blackouts and seriously reduced services on trains.
- There are still Earthquake aftershocks occurring, which naturally is unsettling for everybody.
So I think it's quite clear that even if people wanted to work, it's not really possible right now.
if the core is intact, how can heavy metals be released? the gas that is being released is the cooling liquid

The joys of the interwebs, although there is no way of knowing if this is actually in Tokyo
