An earthquake with an estimated magnitude of 6.3 hit off Kyushu on Friday, injuring a man and disrupting some local transportation networks, authorities said.

The 8:48 a.m. quake occurred at a depth of about 20 kilometers under the seabed off Miyazaki Prefecture. It measured a lower 5 on the Japanese seismic intensity scale to 7 in the city of Miyazaki and Miyakonojo, also in the prefecture, while minor jolts were felt in wider areas of western Japan, the Meteorological Agency said.

In neighboring Oita Prefecture, a 79-year-old man who was trimming trees when the quake struck was taken to a hospital after falling from a stepladder. His condition is not life-threatening, local authorities said.
