“Evacuate immediately from coastal regions and riverside areas to a safer place such as high ground or an evacuation building,” the residents were warned. The earthquake was centered about 15 miles off the coast from Namie, a town close to the nuclear plant. It was followed by large aftershocks measuring 5.4 and 4.8. There were no immediate reports of damage or changes in the radiation level at the Fukushima Dai-ichi nuclear plant, which suffered a triple meltdown after the 2011 earthquake and remains in a highly fragile state. The earthquakes were felt in Tokyo, 160 miles south of the epicenter. Bullet train services were suspended and a fire broke out at a petrochemical plant, although it was soon extinguished. Prime Minister Shinzo Abe was in Argentina Tuesday, following the APEC meeting in Peru, but said the government was ready to respond.
