Tokyo and London — A tsunami warning that had been issued following a strong earthquake off the coast of Miyazaki Prefecture on Monday has been lifted, officials said.
The U.S. Geological Survey put the earthquake’s preliminary magnitude at 6.8. According to the Japan Meteorological Agency, the quake had an intensity of 5 on a scale of 0 to 7.
Japanese and U.S. officials said the quake began around 9:19 p.m. local time and was centered several miles offshore at a depth of about 30 kilometers (30 kilometers).
The Japan Meteorological Agency had issued a tsunami advisory for Miyazaki and Kochi prefectures, with a tsunami expected to be about 1 meter high. A tsunami wave of about 8 inches reached some beaches and ports around 10 p.m., authorities said. They warned residents to continue to stay away from beaches and other waterways.
In Kochi Prefecture, residents in some areas were advised to evacuate.
Japan’s meteorological authorities said about an hour after the quake struck that they were still gathering information about the disruption. Some trains have been suspended, and it is unclear when they will resume service.
Officials warned residents to stay in safe areas as aftershocks and other shaking were likely to continue. Residents were urged to be wary of broken glass and other debris.
No serious damage has yet been reported, and there were no abnormalities in radiation levels or operations at the region’s nuclear power plants, officials said.
