The quake occurred in an area 16 kilometers east of Okcheon, 149 km southeast of Seoul, at 7:03 p.m., according to the Korea Meteorological Administration.

The epicenter was at 36.32 degrees north latitude and 127.75 degrees east longitude, and the depth was 6 km, the agency said.

Fire authorities said they received 80 calls following the quake but no damage had been reported as of 7:10 p.m.
