South Korea was hit by a major 5.4 magnitude natural disaster earlier today.
While the US Geological Survey says it was centered off the coast about 9.3 kilometers northwest of Pohang, state-run Korea Meteorological Administration said the epicenter was inside Pohang.
The tremors were felt all the way in the South Korean capital Seoul some 170 miles away.
The residents of Pohang were told to evacuate, the agency said, adding that reports emerged about buildings shaking following the tremor. There has been no report of human casualties so far.
South Korean officials are assessing the situation.
Buildings in Pohang, North Gyeongsang Province, are seen after an natural disaster of magnitude 5.5 hit the area.
The Cultural Heritage Administration said Wednesday that there is no immediate damage detected to historic buildings and artifacts in Gyeongju, a city adjacent to earthquake-struck Pohang.
South Korea has relatively little seismic activity, compared with Japan to the east.
