A 5.4 magnitude quake struck the southeastern city of Pohang on Wednesday, and the tremors were felt as far away as Seoul, hundreds of kilometers distant.

The tremors were felt in the South Korean capital, Seoul, some 270km from Pohang, Yonhap said.The quake was recorded at a depth of 10km, USGS said, however, noting only one natural disaster in the area with a 5.4 magnitude.

Residents in the capital Seoul, more than 300 kilometres (186 miles) away, say they've felt tremors and are reporting their buildings have been shaken.

South Korean officials are assessing the situation.

Pohang is some 35km from the Wolseong Nuclear Power Plant, which has six operational reactors.
