Jan Mayen Island is a
volcanic island in the
Arctic Ocean and part of the
Kingdom of Norway. It is 55 km long and 373 km2 in area, partly covered by
glaciers. It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by an
isthmus 2.5 km wide. It lies 600 km northeast of
Iceland, 500 km east of central
Greenland and 1,000 km west of the
North Cape, Norway. The island is mountainous, the highest summit being the
Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna, and Nordlaguna. A third lake is called Ullerenglaguna. Jan Mayen was formed by the
Jan Mayen hotspot.
