Novarupta

Novarupta, meaning "new eruption", is a new volcano that was created in 1912 and located on the Alaska Peninsula in Katmai National Park and Preserve, about 290 miles (470 km) southwest of Anchorage. Formed in 1912 during the largest pre-Pinatubo volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma as the 1980 eruption of Mount St. Helens.
