SEOUL -- A 4.1-magnitude earthquake hit the waters off southeast coast of South Korea, Yonhap news agency reported Sunday citing the Korea Meteorological Administration (KMA).

The quake jolted the waters 50 km northeast of the southeastern coastal city of Pohang, North Gyeongsang province at 12:53 pm local time (0353 GMT).

The epicenter, with a depth of 21 km, was at 36.16 degrees north latitude and 129.90 degrees east longitude.

A KMA official was quoted as saying the magnitude was higher than usual although no damage has been reported yet because of the distance between the epicenter and land.
