Study of volcano-ice interaction offers window into geologic past and clues about Earth's long-term climate cycles Glaciovolcanoes, they're called, these rumbling mountains where the orange-red fire of magma meets the frozen blue of glaciers. Iceland's Eyjafjallajökull volcano, which erupted recently, is but one of these volcanoes. Others, such as Katla, Hekla and Askja in Iceland; Edziza in British Columbia, Canada; and Mount Rainier and Mount Redoubt in the U.S., are also...

A rare volcanic eruption is expanding the size of an island in British Overseas Territory. Spectacular new satellite images show that Montagu Island, an erupting volcano in the South Sandwich Islands, South Atlantic has grown by 50 acres (0.2 km2), equivalent to 40 football pitches in the last month. Researchers from the British Antarctic Survey (BAS) and the Hawaii Institute of Geophysics and Planetology (HIGP) were alerted to satellite data showing a large and fast flowing lava flow that...
