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

dont flame me if this is a daft question
but
do other planets have these tectonic plates and have quakes ?

As far as we know most celestial bodies form along similiar mechanics - very simplified mavity pulling chunks together and theres always some flaws so yes most planets and indeed even stars have quakes.

Probably only the inner planets (ones with denser rocky cores). Venus is our sister planet and its believed to have volcanoes under its thick atmosphere. As for Venusquakes well most might be volcano related?

Most probes don't survive on the Veunsian surface for very long due to the massive atmospheric pressure.

Volcanoes are quite common in our solar system...moons of the larger planets have active ones too, Io being a good example.

Indeed. I remember a planet earth or something like that not long ago which talked about how human beings live dangerously close to the edge. Areas of intense geological activity are rich in valuable minerals which are pushed up to the surface. Proximity to water is essential to civilization.

And once you have sited a historical town, how do you go back?

Thus we have the modern day era where millions of people basically live right next door to mount etna. These places were never save to live by, only its too late to go back.

Obviously with a gas giant like Jupiter its a bit different, not sure it exactly has tectonic plates hehe but even Jupiter has disruptions in its structure.

hmm, better but ultimately thats the problem 10MW, maybe a 50MW one in the future, the one that blew up today(I think its that one) is 430MW, supposedly all 53 Nuclear reactors in Japan only make up 35% of their power.

In other words you'd need, just a ridiculous number of 10MW reactors. Even those aren't very safe to accidents because liquid sodium, while stable to much higher temps with less pressure at any given temp than water, if any leaks occur liquid sodium pretty easily explodes on contact with air, so theres other safety risks involved and there have been several incidents with liquid sodium cooled reactors.

AS said, the problem is, too small and safe means very expensive for a given amount of power. Probably very useful in remote places, somewhere like alaksa where one is being planned to be built. Power a small town where other power is not a great option, but for powering a very hungry country, you'd need 43 of those to match the output the one in Japan is doing.

The BN-600 reactor core is 1.03 metres (41 in) tall and has a diameter of 2.05 metres (81 in). It has 369 fuel assemblies, each consisting of 127 fuel rods with an enrichment of 17-26% U235. In comparison, typical enrichment in other Russian reactors is in the range of 3-4% U235. BN-600 reactors use liquid sodium as a coolant. As with most Russian nuclear power plants the station lacks a containment building.

Thats just crazy, huge power, but 127 fuel rods with higher than normal enrichment and no containment buildings. Been going for 28 years though. Just sounds crazy how big/dangerous that kind of thing is.

Gah, the more you read about Nuclear power, the more amazing it seems, and ingenius, and potentially insanely dangerous seeming :p
 
Chernobyl is coming up on worldwide trends on twitter now, interesting how the disasters in Japan re the nuclear explosion makes people think about Chernobyl.

At the end of the day, a normal power plant blows, meh

Yeah, those gas fuelled power stations won't cause any problems for the local people if they explode :P




IMO the fact they evacuated the local people before venting the radioactive gas is proof that the isn't really anything to worry about. When reactor 2 at three miles island went into partial meltdown the Americans opened the emergency venting straight away without warning locals, if the had been a similar situation at Fukushima you can beat they would have done the same thing.
 
What did the Family Guy writer actually say? He's deleted his Pearl Harbour tweet now. Not such a big man now 10,000 people have died and the internet know's you're a **** ;)

Also, Twitter is trending big on Pearl Harbour: seems that picture of those Facebook idiots is doing the rounds bigtime. They left their names on it, too! I wonder how that'll work out for them...

Another earthquake, 6.0 this time the nuclear plant might still be in trouble.

From what I hear it would need a magnitude 7 or higher quake in the local area to be of any real concern.

You can't really use that as a pattern to predict the outcome, at this stage anything could potentially happen unexpectedly.

Damn it, If I knew a decent language I would totally write up a tool to grab all the names that listed pearl harbour and then post them on a site for all to easily see.
