Jan Mayen

Jan Mayen is a Norwegian volcanic island situated in the Arctic Ocean. 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 a 2.5 km wide isthmus. 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.

Although administered separately, in the ISO 3166-1 standard Jan Mayen and Svalbard are collectively designated as Svalbard and Jan Mayen, with the two-letter country code "SJ".
