A strong earthquake with a preliminary magnitude of 6.1 has struck just off the coast of northeast Japan, just two days after a powerful earthquake. There were no immediate reports of damage and no tsunami alert was issued.
The latest earthquake happened at about 6:23 a.m. local time on Thursday and was centered about 37 kilometers (23 miles) southeast of the town of Namie in Fukushima Prefecture. It struck at a very shallow depth.
Japan's Meteorological Agency (JMA) put the preliminary magnitude of Thursday's earthquake at 6.1, while the United States Geological Survey (USGS) put the magnitude at 5.6. The cause for the difference in magnitude was not immediately clear.
JMA reported that moderate shaking had been felt across Fukushima Prefecture, with very light shaking being felt as far away as the capital Tokyo. There were no immediate reports of any damage or injuries as a result of the latest earthquake.
"Although there may be slight sea-level changes in coastal regions, this earthquake has caused no damage to Japan," JMA said. It added that there was no threat of a tsunami.
Thursday's earthquake is believed to be an aftershock to a powerful 7.4-magnitude earthquake that struck the same area at about 6 a.m. on Tuesday. That earthquake caused some damage, injured more than a dozen people and generated a small tsunami.
