Powerful earthquakes just over 10 minutes apart rattled Japan and India on Tuesday, triggering panic on fears of a tsunami in the Andaman Islands and injuring more than 100 people southwest of Tokyo. The unrelated quakes struck in the early hours, shutting down Japanese bullet train services and a nuclear power plant and causing a landslide that closed a major highway near the Japanese capital. A 43-year-old woman was found dead after the tremor, buried under a pile of books, said a prefectural police official in Shizuoka, west of Tokyo. "We are investigating whether her death is related to today's earthquake," he said. At least 110 people were injured, mostly by falling objects such as television sets, including three who were hospitalised in serious condition, prefectural government officials and police said.
