A strong earthquake triggered a small tsunami along Japan's northeastern coast Wednesday and shook buildings hundreds of miles away in Tokyo. There were no immediate reports of significant damage or injuries. Some train lines in the northeastern prefecture of Iwate were temporarily stopped after the magnitude 7.3 quake, but they were restarted shortly after. Tohoku Electric Power said there was no damage at its nuclear power facility in the region. A 24-inch (60-centimeter) tsunami reached the coastal town of Ofunato and other towns reported smaller waves reached shore about 30 minutes after the quake, which occurred at 11:45 a.m. It was centered about 90 miles (150 kilometers) off the northeastern coast at a depth of about five miles (eight kilometers), Japan's meteorological agency said.
