The causative fault was the Ărnes Fault and a large number of surface fissures were mapped along this structure in the days following the event.

The second earthquake occurred at 00:51 UTC on 21 June at a depth of 5.1 km. The extent of aftershocks defined an 18 km fault rupture down to 8 km depth. The causative fault was the
Hestfjall Fault. Surface fissures were developed over a distance of about 25 km.

According to historical records, there have been 33 damaging earthquakes in the SISZ from the 11th century up to June 2000, with the latest being in 1896 and 1912.
