A 5.4 magnitude natural disaster shook South Korea's southeastern coastal region Wednesday afternoon, breaking some windows and crumbling walls near the epicenter.
The tremor occurred in an area 9 km north of the coastal city of Pohang in North Gyeongsang province at 2.29 p.m, according to the Korea Meteorological Administration.
South Korea's state-run Korea Meteorological Administration measured the quake at the same strength but said the epicenter was inside Pohang.
There have been no reports of human casualties so far.
Residents in Pohang city just 5.6 miles from the epicentre of the quake were told to evacuate.
South Korean officials are assessing the situation.
South Korea has relatively little seismic activity, unlike neighbouring Japan.
The Pohang quake is the strongest Korea has experienced since 2016, after the magnitude 5.8 natural disaster in Gyeongju.
A rare natural disaster of magnitude 5.4 rattled South Korea on Wednesday, its second most powerful quake on record, shaking buildings but causing no major damage or injuries.
