According to the Korea Meteorological Administration, an aftershock of 5.4 was witnessed minutes later.
So far, there have been no reports of fatal casualties with 7 minor injury cases as of 4:32 PM KST, but it seems the quake did take a toll on building exteriors, vehicles, and in some cases, indoors.More news: 25 injured by collision between two trains at Singapore's Joo Koon station
The residents of Pohang were told to evacuate, the agency said, adding that reports emerged about buildings shaking following the tremor.
South Korean media showed crumbled walls piled on parked cars, broken windows from some buildings and elementary school students taking shelter on a playground.
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.More news: World's richest 1% of people now own half global wealth, finds study
