A magnitude 6.3 earthquake strikes northern Japan, according to reports citing the Japan Meteorological Agency (JMA). The quake’s epicentre is located off the coast of Miyagi prefecture in the Pacific, with the JMA placing the depth at about 50km. One report says the earthquake occurs at 8:22 pm local time in Pacific waters off northern Miyagi. Both outlets state that no tsunami warning is issued following the earthquake. The available information focuses on the quake’s location, timing and depth, and does not mention any immediate casualties or damage. As the reports agree on the magnitude and key parameters, the main common points are the estimated size of the quake, its offshore location near Miyagi, the approximate depth, and the absence of a tsunami alert from authorities. Further impacts, if any, are not detailed in the provided sources.
