- We had no warning about this and it is not possible to say when a seismic event will take place, says Fredrik Björkenwall, acting press officer at LKAB. When measuring seismic activity in a mine the magnitude is lower, the frequencies higher and you want great precision at short distances. This is why a local magnitude scale is produced for the conditions that apply at the specific mine. LKAB last reported a seismic event occurred at Kiruna on April 19, saying its preliminary magnitude was 1.77 according to the local scale.
