At least seven miners are missing and one died after an earthquake occurred at the Rudna mine in Polkowice in southwestern Poland, state news agency PAP reported on Tuesday.
An earthquake of magnitude 4.4 struck at 9:09 p.m. (2009 GMT), according to the U.S. Geological Survey. It said the quake was very shallow, only 10 km (6.2 miles) deep, which would have magnified its effect at the mine belonging to state-run copper producer KGHM.
According to Polish state authorities, quoted by PAP, the earthquake’s epicentre was located 1,500 metres (5,000 feet) underground.
“There were 16 people in the danger zone. Some of them were walked out,” a spokeswoman for the company was quoted as saying by private radio RMF FM.
The one miner who died was among nine people evacuated, according to media reports.
Three miners who were injured the most are in hospital, their condition is stable, and their life is not threatened, according to RMF FM. They suffered backbone and head injuries.
