Leaks and damage at Onagawa nuclear power plant, Miyagi Prefecture, Japan

Radio Free Europe/Radio Liberty reports that after yesterday's 7.1 magnitude aftershock in Japan, the Tohuku nuclear utility's Onagawa nuclear power plant in Miyagi Prefecture to the north of the now-infamous Fukushima Daiichi nuclear power plant has reported water leaks throughout its three reactor complex, as well as damage to a secondary containment building's "blow out walls." The Onagawa nuclear power plant was -- like Fukushima Daiichi -- thrown into an initial state of crisis on March 11th due to the 9.0 magnitude earthquake and consequent tsunami. Miyagi Prefecture, in fact, is considered to be the hardest hit prefecture of all by the tsunami in northeastern Japan.
