The earthquake occurred 18 kilometers south of Lycksele at a depth of about 25 kilometers, according to the Swedish National Seismic Network. This location places the epicenter in a region known for seismic activity, though events of this magnitude remain rare in Sweden. The depth suggests it originated within the Earth's crust, typical for tectonic activity in the area.
Many people experienced shaking in the ground in several places in Västerbotten, as reported by official sources. Several people have reported on social media that they felt the earthquake, indicating the tremor's reach beyond immediate epicentral areas. The exact number of people who felt the earthquake has not been confirmed, and what specific damage, if any, was caused by the earthquake remains unclear at this time.
It is unusually large. There are typically no more than one to two that large per year in Sweden.
This is the largest earthquake that has occurred in Västerbotten since the earthquake east of Burträsk in May 2024, the Swedish National Seismic Network stated. The earthquake was unusually large for Sweden, with typically only one to two of that size per year, according to seismologist Björn Lund at Uppsala University. According to SVT Nyheter, Björn Lund described the event as unusually large, noting there are typically no more than one to two that large per year in Sweden. Whether there were any aftershocks following the earthquake has not been reported, and the precise geological cause of this specific earthquake event is still under investigation.
The area is unusually active with around 1,000 earthquakes per year linked to the Burträsk fault, Aftonbladet reports. This geological context helps explain the frequency of seismic events in Västerbotten, though most are minor compared to Saturday's tremor. The Burträsk fault is a known source of tectonic activity in northern Sweden, contributing to the region's elevated earthquake count. If any emergency services were dispatched or if any safety measures were implemented in response to the earthquake has not been detailed by authorities. Seismologists continue to monitor the region for further activity, given its historical patterns of seismic unrest.
