Short summary
The Pärvie fault system extends up to 155km, and its scarps have offsets of tens of meters at the surface in northern Sweden. These fault scarps are inferred to have formed during earthquakes with magnitudes up to 8 at the time of the last deglaciation. In this study, we have mapped the fault system to deeper levels, by a new 22km long 2-D seismic reflection profile. Based on the present and previous seismic data, locations for future boreholes for drilling into the fault system are proposed.
