TOKYO, July 10 (UPI) -- A strong earthquake that rumbled off the coast of northeastern Japan Sunday produced tsunamis only 6 inches high, officials said.

The Japan Meteorological Agency measured the quake at a magnitude of 7.3, up from an initial 7.1, Kyodo News reported. The U.S. Geological Survey put it at a magnitude of 7.

The temblor occurred off the east coast of Honshu, Japan's largest island, just before 10 a.m. local time at a depth of 21.7 miles. It was centered 131 miles east off Sendai, 148 miles east-northeast of Iwaki, 155 miles east of Fukushima and 254 miles northeast of Tokyo, the quake-monitoring agency said.

The small tsunamis were observed at Ofunato port in Iwate at 10:44 a.m., Soma Port in Fukushima at 11:11 a.m. and Ofunato port again at 11:20 a.m., Kyodo said.

The tsunami warning, which had called for surges of up to 30 inches, was lifted at 11:45 a.m.

No damage or injuries were reported as a result of the quake or tsunamis. No abnormalities were reported by Tokyo Electric Power Co. at its nuclear power plants.

The region had been decimated by the March 11 9-magnitude quake and subsequent tsunami that claimed more than 15,500 lives and left nearly 5,400 people missing. That disaster also caused severe damage to Tepco's Fukushima Daiichi nuclear power plant.
