million homes suffered blackouts in Japan's northeast Friday after a new earthquake killed three people and piled more misery on a region buried under the rubble of last month's devastating tsunami. The northeastern coast was still reeling from the destruction wrought by a jumbo 9.0-magnitude earthquake on March 11, with tens of thousands of households without power or water. The 7.1-magnitude aftershock Thursday threw even more areas into disarray and sent communities that had made some gains back to square one. Gasoline was scarce again, and long lines formed at stations. Stores that had only recently restocked their shelves sold out of basics Friday and were forced to ration purchases again. Still, the latest quake did far less damage, generated no tsunami and largely spared the region's nuclear plants. Some slightly radioactive water spilled at one plant, but the tsunami-crippled Fukushima Dai-ichi complex reported no new problems. Matsuko Ito, who has been living in a shelter in the small northeastern city of Natori since the tsunami, said there's no getting used to the terror of being awoken by shaking. She said she started screaming when the quake struck around 11:30 P.M. “It's enough,” the 64-year-old while smoking a cigarette outside. “Something has changed. The world feels strange now. Even the way the clouds move isn't right.” The latest tremor — the strongest since the day of the tsunami — cut power to more homes, though it was quickly restored to many. More than 450,000 households were still without electricity Friday evening, said Souta Nozu, a spokesman for Tohoku Electric Power Co., which serves northern Japan. That includes homes in prefectures in Japan's northwest that had been spared in the first quake. Six conventional plants in the area were knocked out, though three have since come back online and the others should be up again within hours, Nozu said. But with power lines throughout the area damaged, it was not clear whether normal operations would be restored, he said. In Ichinoseki, lines formed outside a supermarket when it opened Friday morning. An employee with a flashlight escorted each customer around the store and jotted the price of each selected item in a pad.
