Beerenberg

Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is high and is the world's northernmost subaerial active volcano. The volcano is topped by a mostly ice-filled crater about wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side.
The upper slopes of the volcano are largely ice-covered, with several major glaciers including five which reach the sea. The longest of the glaciers is the Weyprecht Glacier, which flows from the summit crater via a breach through the northwestern portion of the crater rim, and extends about down to the sea.
Beerenberg is composed primarily of basaltic lava flows with minor amounts of tephra. Numerous cinder cones have been formed along slope fissures.
Its most recent eruptions took place in 1970 and 1980, both of which were flank eruptions from fissures on the northeast side of the mountain. Other eruptions with historical records occurred in 1732, 1818, and 1851.
Its name is Dutch for "Bear Mountain", and comes from the polar bears seen there by Dutch whalers in the early 17th century.
