According to the city of Pohang on the 3rd, at 2:50 pm on the 1st, an accident occurred at the Jungang Steel Factory in Pohang Steel Industrial Complex 3, Daesong-myeon, Nam-gu, Pohang.
The area of the settlement is about 1,600m2 and the depth is 2~2.5m. No human injury occurred because the factory was not operated. The cause of the settlement has not yet been identified.
The city is investigating the cause of the settlement, such as whether it is affected by the installation of a buffer storage facility in the river behind the accident plant or if there is a problem with the ground.
In order to prevent further collapse, it is planned to prioritize emergency recovery and establish a recovery plan through ground investigation.
In Pohang, on February 14, last year, on February 14, the road and part of the sidewalk were settled in three round trips to Nam-gu, resulting in a sink hole of 4 meters in width, 5 meters in length, and 4 meters in depth.
On November 3, 2019, a large sink hole of about 5 meters in width and length occurred as part of the road went down by three lanes one-way about 450 meters away.
In both places, no human injury occurred thanks to active reports from citizens.
In April-May 2018, the ground subsided while digging an officetel at an officetel construction site in Hado-dong, Nam-gu near the Pohang Express Bus Terminal.
In the first half of 2018, the surrounding land was turned off during the underground excavation work at a new officetel construction site in Jukdo-dong, Buk-gu.
Pohang has many soft sedimentary rocks throughout the city.
The old city center is formed by reclaiming a delta-shaped island at the estuary of the Hyeongsan River, and the ground is weak enough to create a small wave of land.
In addition, on November 15, 2017, the ground was severely shaken by a magnitude 5.4 earthquake and aftershock.
As a result, Pohang’s ground is inevitably weak.
One citizen said, “I feel anxious as the subsidence of the factory and various kinds of land loss can lead to a serious accident.”
