Novarupta
Novarupta (meaning "newly erupted" in Latin) is a volcano that was created in 1912, located on the Alaska Peninsula in Katmai National Park and Preserve, about southwest of Anchorage. Formed during the largest volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma of the 1980 eruption of Mount St. Helens.
