The Pärvie fault line

The inland ice cover melted and the Earth trembled.

The Baltic shield is since millions of years a tectonically rather calm area. However, when the latest inland ice retreated from northern Sweden c. 10,000 years ago, crustal tension was released and triggered earthquakes up to M 7–8, faults and hundreds of landslides. Furthermore, theses faults seem to be unique in a global perspective, since no faults of the same magnitude in a corresponding geological environment has been discovered. The Pärvie fault escarpment is 150 kilometres long and usually 5–10 metres high.
