베에렌베르크 화산

Jan Mayen

성층화산 · Norway · 2197m

Glacier-covered Beerenberg volcano rises above the western coast of Jan Mayen at the northern end of the island. This remote island in the Norwegian Sea along the Mid-Atlantic Ridge about 650 km NE of Iceland consists of two volcanic complexes separated by a narrow isthmus. The Beerenberg stratovolcano has a 1-km-wide summit crater and numerous flank cinder cones. Reported eruptions from Beerenberg date back to the 18th century.

Remote Jan Mayen Island, located in the Norwegian Sea along the Jan Mayen Ridge about 650 km NE of Iceland, consists of two volcanic complexes separated by a narrow isthmus. The large Beerenberg basaltic stratovolcano (Nord-Jan) forms the NE end of the 40-km-long island, which is ringed by high cliffs. The glacier-covered Beerenberg has a 1-km-wide summit crater and numerous cinder cones that were erupted along flank fissures. It is composed primarily of basaltic lava flows with minor amounts of tephra. Reported eruptions from Beerenberg date back to the 18th century. The SW tip of Jan Mayen contains the Holocene Sor-Jan cinder cones, tephra rings, and trachytic lava domes were erupted from short fissures with a NE-SW trend.

Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is 2,277 m (7,470 ft) high and is the world's northernmost subaerial active volcano and the only active volcano in Norway. The volcano is topped by a mostly ice-filled crater about one kilometre wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side.
