Mount Spurr and the surrounding caldera are deeply mantled by spectacular glaciers, with fifteen times the ice volume found on Mount Rainier. Crater Peak has erupted explosively twice in the last century [1] and Mount Spurr exhibited a dramatic “ice cauldron” hydrothermal event from 2004 to …

4 days ago · For humans, the main impact of Mount Spurr's eruption would likely be ash. In 1992, the eruption at Crater Peak shut down Anchorage's airport and dusted the city with 0.1 inches (3 millimeters) of ...

Oct 23, 2024 · The largest hazard from the 1992-94 eruptions at Mt. Spurr was all the ash that was emitted. Anchorage saw 3-5 millimeters of ash fall across multiple blasts from Spurr that sent ash and volcanic aerosols over 60,000 feet (19,000 meters) into the atmosphere.

Dec 6, 2024 · Mount Spurr, located on the Volcanic Ring of Fire, is one of 53 volcanoes in Alaska that have been active within the last 250 years. An increase in the number of earthquakes under a volcano near Alaska’s largest city this year has geologists paying attention.

Mount Spurr forms the southern buttress of the Tordrillo Range, with an active vent on Crater Peak below the summit. This 11,070-foot volcano last erupted in September of 1992, when it dusted the region with an eighth-inch layer of volcanic ash and shut down the regular life in Alaska’s largest city for several days.
