There never was a good war or a bad peace. ~Ben Franklin
Had the massive 8.9 Richter-scale earthquake that has just savaged Japan hit off the California coast, it could have ripped apart at least four coastal reactors and sent a lethal cloud of radiation across the entire United States. (http://nukefree.org/ace-hoffman-computerized-graphic-what-if-chernobyl-h... )
The two huge reactors each at San Onofre and are not designed to withstand such powerful shocks. All four are extremely close to major faults.
All four reactors are located relatively low to the coast. They are vulnerable to tsunamis like those now expected to hit as many as fifty countries.
[NukeNet] Meltdown at Fukushima Daiichi Unit 1 appears to have started..A Tokyo Channel 12 TV news item just said that radioactivity is 70 times higher than normal around the Fukushima I (Daiichi) Plant Unit 1 and 1000 times higher than normal in the control room. Cesium has been detected around the site. Water is below the level of the fuel rods. There is a possibility of damage and "a high possibility that meltdown has begun".
Please note that besides the situation at Fukushima, we are also concerned about the state of the Onagawa nuclear power plant about which there is no news except that the nearest towns were totally inundated by tsunamis.
