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.

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 …

3 days ago · The Alaska Volcano Observatory is closely monitoring Mount Spurr, which is located about 75 miles west of Anchorage. “AVO continues to monitor activity at Mount Spurr for signals that would indicate that the volcano is moving closer to an eruption. Based on previous eruptions, changes from current activity in the earthquakes, ground deformation, summit lake, and fumaroles would be expected ...

Feb 16, 2025 · Hundreds of small earthquakes have occurred beneath Mount Spurr, located in the volcanically active Aleutian Arc and approximately 75 miles west of Anchorage, according to the Alaska Volcano...

Steam was occasionally visible rising from Spurr’s summit during clear weather. On December 10, there was a M2.8 earthquake beneath the summit, and a few more episodes of tremor were recorded that week. On Wednesday, December 18, AVO staff conducted a gas flight at Mount Spurr. Measurements of H2O, SO2, H2S, and CO2 were collected.

Feb 15, 2025 · Mount Spurr erupted once in 1953 and three times in 1992, according to the observatory. Both years saw eruptions at the Crater Peak vent, located two miles south of the volcano’s summit.

Feb 13, 2025 · 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...

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.

Feb 8, 2025 · Mount Spurr’s summit crater is seen from the air on March 7, 2023. Escaping gas from one of the volcano’s main fumarole and a dry crater floor can be seen. (Taryn Lopez/Alaska Volcano Observatory)
