The New York Times has reported that the stress from large quantities of emergency cooling water in Fukushima Daiichi reactor blocks could exacerbate the violent force exerted by powerful aftershocks, further risking breach of vital containment structures holding back the motherlode of radioactivity from escaping into the environment. Meanwhile, nearly a month after the March 11 earthquake and tsunami, police are at long last entering the 12 mile radius radiological evacuation zone, in search of 4,200 missing persons.
