Feb 6, 2025 · A map of Mount Spurr, Alaska, showing monitoring stations operated by the Alaska Volcano Observatory and hypocenters of earthquakes that occurred from January 1, 2024 through February 6, 2025. Mount Spurr is about 75 miles (120 km) west of Anchorage. The seismic activity shown on the map is higher than normal and likely reflects intrusion of ...

Mount Spurr (Dena'ina: K'idazq'eni) is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898.

3 hours ago · Mount Spurr, located near Anchorage, Alaska, is experiencing increased seismic activity, with earthquake frequency rising from 30 to 125 per week since April. This suggests a potential eruption ...

1 hour ago · Mount Spurr, an Alaskan volcano shuddering with small earthquakes for 10 months, could erupt soon. The Alaska Volcano Observatory (AVO) stated on February 7 that an eruption would "most likely ...

Mount Spurr is an ice and snow-covered stratovolcano complex, meaning that it is a large, cone-shaped volcano formed by lava flows, pyroclastic deposits, mudflow deposits, and lava domes. The ...

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 …

2 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.
