5.5 magnitude quake hits off South Korea's coast

5.5 magnitude quake hits off South Korea's coast

There were no immediate reports of any casualties or injuries.

The quake was centered off the coast about 9.3 kilometers (5.8 miles) northwest of the port city of Pohang, according to the U.S. Geological Survey. The Pohang natural disaster is the strongest Korea has experienced since 2016, after the magnitude 5.8 quake in Gyeongju.

The tremors were felt all the way in the South Korean capital Seoul some 170 miles away.

A number of windows were broken and walls crumbled beneath structures close to the central point of the natural disaster. USGS reported the tremor struck at a depth of 10km at 2.29pm (1.29pm, Singapore time).

The agency sent out an quake alert via a mobile network which asked some of the local residents in the affected area to evacuate immediately.

No severe damage has been reported to test venues in the southeastern city where a magnitude 5.4 quake, the second strongest on record, occurred. No immediate damage was reported in the firm's steel mills.

But seismic activity is closely monitored because a spike in activity is often the first indication that North Korea has carried out a nuclear test.

"All reactors, including those in Gyeongju, are operating normally without power shutdown or decreased power output", the KHNP said in a statement. A third aftershock with a 3.6 magnitude was recorded later, the weather agency said.
