The Kiruna mine is an iron ore mine in Kiruna in Norrbotten County, Lapland, Sweden. The mine is owned by Luossavaara-Kiirunavaara AB (LKAB), a large state owned Swedish mining company. In 2018, the mine produced 26.9 million tonnes of iron ore. The Kiruna mine has an ore body which is 4 km (2.5 mi) long, 80 metres (260 ft) to 120 metres (390 ft) thick and reaching a depth of up to 2 km (1.2 mi). Since mining began at the site in 1898, the mine has produced over 950 million tonnes of ore. As of 2020, the main haulage level is 1,365 m below the ore outcrop at Kiirunavaara that existed prior to mining. In 2004, it was decided that the present centre of the city would need to be relocated to accommodate mining-related subsidence. The relocation would be made gradually over decades. On May 18, 2020, an earthquake of approximate 4.9 Mw was triggered in the footwall of the mine. The earthquake was not natural but induced by the mining activity.
