8 Department of Earth Science, Geodynamics Group www.geo.uib.no The earthquake occurred likely between the Billedfjord and Lomfjorden faults. More than 2000 aftershocks are recorded.

9 Department of Earth Science, Geodynamics Group www.geo.uib.no More than 200 aftershocks are located.

10 Department of Earth Science, Geodynamics Group www.geo.uib.no MT-inversion on regional stations (depth fixed to 15 km)

11 Department of Earth Science, Geodynamics Group www.geo.uib.no MT-inversion on local stations

12 Department of Earth Science, Geodynamics Group www.geo.uib.no Focal mechanism based on the first motion polarities (left) and based on the slip inversion (right)
