( CNN ) -- A major earthquake struck off Japan 's northeastern coast Sunday , prompting tsunami advisories that were later canceled , the Japan Meteorological Agency ( JMA ) said . Small tsunamis were observed along the coast , measuring between 10 and 20 centimeters , said the JMA . There were no immediate reports of injuries or damage , according to the Japanese news agency Kyodo . The U.S. Geological Survey said the earthquake struck at 10:57 a.m. at the epicenter , about 130 miles east of Sendai . The earthquake was more than 20 miles deep and had a magnitude of 7.0 , the USGS said . The JMA measured the magnitude of the quake at 7.1 . Tsunami advisories were issued -- and then canceled -- for the coastal regions of Iwate , Miyagi and Fukushima . The areas were among the hardest hit by this year 's devastating earthquake and tsunami . Officials in Ofunato , a city in Iwate , advised residents to evacuate . The JMA , immediately after the quake , forecast the height of the tsunami could reach half a meter ( about 20 inches ) . No immediate abnormalities were reported at nearby nuclear facilities , according to Kyodo . Three reactors at the Fukushima Daiichi nuclear power plant suffered meltdowns after the March 11 earthquake and tsunami that devastated northern Japan . The tsunami swamped the plant and knocked out cooling systems that kept the three operating reactors from overheating , leading to the worst nuclear accident since Chernobyl . Tremors from Sunday 's quake were felt as far away as Tokyo . `` It 's just a continuing of the aftershocks of that devastating 9.0 , '' said Dale Grant , a geophysicist with the USGS , referring to the March quake . `` These kinds of aftershocks are likely to occur for some time . '' CNN 's Yoko Wakatsuki contributed to this report .
