A dated volcano‐tectonic deformation event in Jan Mayen causing landlocking of Arctic charr
ABSTRACT We provide the first documentation of tectonic deformation resulting from a volcanic eruption on the island of Jan Mayen. Vertical displacement of about 14 m southwest of the stratovolcano Beerenberg is associated with an eruption in ad 1732 on its southeastern flank. The age of the uplift...
