Large-scale mining for ore in underground mines can lead to seismic activities. This means quaking or tremors occur in the bedrock. LKAB monitors the activity in its mines in Kiruna and Malmberget, and works to reduce these tremors.
Do you have any questions or concerns about seismic events? If so, email firstname.lastname@example.org or send a letter to LKAB, Information Dept., SE-981 86 Kiruna, SWEDEN.
