Beerenberg, a stratovolcano, is the northern-most active subaerial volcano on Earth. The volcano, mostly covered by glaciers, forms the north-end of Jan Mayen Island, 375 miles (600 km) north-northeast of Iceland.

Beerenberg has erupted six times between 1732 and 1985. All of these eruptions were on flank vents and produced lava flows and scoria cones. The most recent eruptions were in 1970, 1973, and 1985.

The 1970 eruption began on September 18 and continued to January, 1971. Intense storms hid the onset of the eruption. A commercial pilot spotted the eruption cloud on September 20. It was the only historic eruption witnessed in modern times. The eruption was large, erupting at least 0.5 cubic km of basalt from a 3.7 mile (6 km) long fissure that ran from sea-level to an elevation of 3,000 feet (1,000 m). There were at least five active craters.

The 1985 eruption began on January 6, 1985 and lasted only 35-40 hours. In that brief time about 7 million cubic meters of lava was erupted (rougly enough to bury a football field in 1400 yards of lava!). Earthquakes, with magnitudes up to 5, occurred during the eruption. The eruption was thought to be from a leaky fracture zone not the Jan Mayen magma system proper (Imsland, 1986). The vent was 22 miles (35 km) from the settlement. -
