Description

General physical description:

Mount Spurr is a prominent member of the Cook Inlet volcanoes and is clearly visible from Anchorage on sunny days. The dramatic edifice is made up of several volcanic features. The ancestral Mount Spurr was a large volcano that catastrophically collapsed in early Holocene (post-glacial) time^[1], leaving behind a three-mile-wide caldera with a southeasterly facing breach and a spectacular debris-avalanche deposit in the Chakachatna River valley^[1]. Since the collapse, two separate vents have built up their own edifices atop the remains of ancestral Spurr. The current Mount Spurr is a roughly conical lava dome complex^[2] (summit elevation 11,070 ft/3,374 m) that rises several thousand feet above the caldera. Crater Peak, the second and more recently active vent, is a stratocone that has grown at the margin of the caldera, within the breach, and has a summit elevation of 7,575 ft (2,309 m)^[1]. Mount Spurr and the surrounding caldera are deeply mantled by spectacular glaciers, with fifteen times the ice volume found on Mount Rainier^[1]. Crater Peak has erupted explosively twice in the last century^[1] and Mount Spurr exhibited a dramatic “ice cauldron” hydrothermal event from 2004 to 2006^[3]. Any future eruption of Mount Spurr or Crater Peak would likely be severely disruptive to Anchorage and the surrounding areas.

Location:

Mount Spurr is the secondmost northeasterly volcano in the Aleutian volcanic arc. It is found at the southernmost end of the Tordrillo Mountains, which are south of the Alaska Range and to the northwest of Cook Inlet^[1]. It is bordered to the south by the Chakachatna River valley and to the southwest by the river’s headwaters, Chakachamna Lake, which is partially dammed by Barrier Glacier flowing out of the Tordrillo Mountains^[1]. Mount Spurr is 78 miles (126 kilometers) northwest of Anchorage, and the closest community is Beluga, 37 mi (60 km) to the southeast. It is 56 mi (90 km) south of Mount Hayes and 58 mi (93 km) northeast of Redoubt Volcano.

Notable eruptions:

Mount Spurr is notable for several major eruptions and periods of unrest that have occurred in the past 100 years. Crater Peak, the southern vent of Spurr volcano, erupted explosively in 1953 and 1992^[1]. Prior to the 1953 eruption, nearby Alaska residents had sometimes noted steam rising from the peak, which occurred more frequently in late spring 1953^[4]. On July 9, a single powerful explosion about an hour long created a 30,000 ft (10,000 m) high eruption plume^[1]. An Air Force jet reported that it flew into the ash cloud for just a moment, but emerged with sandblasted paint and a frosted windscreen^[5], an early example of the dangers of aircraft encounters with volcanic ash. About a quarter inch (6 mm) of ash fell in Anchorage, 78 mi (126 km) away, shutting down Ted Stevens International Airport for two days, and ashfall was reported as far away as Valdez^[1]. The eruption also caused pyroclastic flows that mixed with snow and ice and heavy local rainfall to create lahars that temporarily dammed the Chakachatna River^[1].

Seismic monitoring of Mount Spurr began in 1971. Starting in August 1991, increased seismicity was noted beneath Crater Peak. Between November 1991 and June 1992 seismicity increased further beneath the entire Spurr edifice. In mid-June 1992, seismicity increased still further^[6] and the small crater lake within Crater Peak rapidly changed color and heated to boiling. The eruption began at 7:04 am June 27 following almost 19 hours of vigorous volcanic tremor and a shallow earthquake swarm under Crater Peak and was quickly reported by a passing Alaska Airlines pilot^[7]. This time the eruption plume, which reached 47,500 ft (14,500 m), was blown to the north and 0.04-0.08 in (1-2 mm) of ash fell in Denali National Park. Once again, pyroclastic flows occurred and mixed with snow, ice, and water to form lahars that dammed the Chakachatna. Two more major explosions occurred at Crater Peak on August 18 and September 16-17. Winds carried ash from the August 18 eruption to the east, depositing as much as 0.12 in (3 mm) of ash in Anchorage that closed the Anchorage airport for 20 hours. Ash from the September 16-17 explosion moved in a more northeasterly direction and heavily impacted populated areas in the Matanuska and Susitna valleys^[7].

In 2004, unusual activity was noted at the summit of Mount Spurr, which until then had been thought to be much less likely to erupt than Crater Peak^[1]. Several muddy debris flows appeared on the summit’s ice-covered flanks, and snow and ice at the summit melted and collapsed inward to create an “ice cauldron,” a heated crater lake that grew by melting the summit ice from below^[2]. The ice cauldron continued to grow for over two years and featured dramatic boiling jets and fumaroles (one dubbed “Jumbo Jet”) before cooling in 2006 and becoming snow covered once again^[3]. Addition of new seismic instruments allowed scientists to determine that magma was actually closer to the surface below Mount Spurr summit than below Crater Peak during this period^[8]. Earthquake swarms have since occurred in 2012 and 2014-2017, though no eruption has yet followed^[9],^[10],^[11],^[12],^[13].

Several prehistoric eruptions from both vents of Mount Spurr are recorded in ash or tephra layers found in Alaska.

Special hazard info:

Mount Spurr (including Crater Peak) is listed as “very high threat” by the most recent edition of the USGS National Volcanic Threat Assessment^[14]. This is because it has erupted frequently in recent history and has shown signs of unrest since its most recent eruption. It is near a large international airport with a high daily passenger volume and would likely disrupt air travel for some time in any future eruption and cut off air access to interior Alaska^[14]. Because Mount Spurr is covered with an enormous volume of glacial ice, future eruptions are very likely to cause significant lahars, as happened in 1953 and 1992^[1]. If a lahar dammed the Chakachatna River, the river could back up to Chakachamna Lake and even “float” the ice dam there created by Barrier Glacier, which would likely lead to a very large flood that could reach Cook Inlet. As there are no permanent structures within the Chakachatna valley, this would luckily pose minor risk to people^[1].

Name Origin

A.H. Brooks named Mount Spurr in 1900, for Josiah Edward Spurr, a U.S. Geological Survey geologist who led an expedition in the area in 1898 (Orth, 1971).

Current Activity

_{April 2, 2025, 10:25 am}

Unrest continues at Mount Spurr volcano. Seismicity remains elevated with numerous small, shallow volcanic earthquakes detected beneath the volcano over the past day. No activity detected in satellite data or web-camera data.

AVO continues monitoring activity at Mount Spurr for signals indicating that the volcano is moving closer to an eruption. Based on previous eruptions, changes from current activity in the earthquakes, ground deformation, summit lake conditions, and fumarolic activity would be expected if magma began to move closer to the surface. Therefore, if an eruption occurred, it would be preceded by additional signals allowing warning.

The volcano is monitored using local seismic, infrasound, web camera, and GNSS stations along with regional infrasound, lightning networks and satellite data.

Seguam Eruption Timeline

Seguam 1786

1786 — 1790

Grewingk (1850, translated 2003 by Fritz Jaensch) states that from 1786 until 1790, Seguam was active. Sarychev (translated from Russian in 1806 and 1807, republished 1969) wrote that in 1790, Seguam was "formerly to have had a volcanic mountain."

Seguam 1827

1827

Grewingk (1850, translated 2003 by Fritz Jaensch) states that Seguam was reported smoking in 1827 by Lutke.

Seguam 1891/12

December 1891

Jaggar (1927) reports Seguam "broke into eruption for a week in December, 1891." Coats (1950) classifies the eruption as a minor explosive eruption.

Seguam 1892/4

April 15, 1892

Jaggar (1927, citation 1868) reports "a terrific eruption in the spring of 1892, making detonations heard at the native village on Atka, 75 miles away, and exhibiting two jets of cauliflower clouds."
Jaggar (1927, citation 2639) reports Seguam in 1892 "violently active, so that its eruption was seen from Nazan Bay [Atka] and the sky was darkened by the ash."
Presumably these reports refer to the same eruption from Seguam sometime during 1892, although 2 separate eruptions could have occurred.

Seguam 1902

1902

Coats (1950) and Dunn (1906) report a suspected major explosive eruption at Seguam in 1902. Miller and others (1998) and McGimsey and Miller (1995) report that this eruption occurred in 1901.

Seguam 1927

1927

Coats (1950) reported smoke from Seguam during 1927.

Pyre Peak 1977/3

March 6, 1977 — March 8, 1977

From Miller and others (1998): "In early March, 1977 the crew of the U.S. Coast Guard Cutter Mellon reported eruptive activity. Eight lava fountains, up to 90 m high were noted along a radial rift about 1 km long and about 2.5 km southwest of the summit. At least two tongues of lava were extruded. The larger flow, 1 km wide, extended 1 km south. Neither tongue entered the sea. Pyroclastic material was also produced during the event. Dense clouds containing black ash and incandescent fragments were emitted from one or both of the vents effusing lava, and a coating of fine ash was visible on the surrounding snow. By March 8th, lava extrusion had apparently ceased, but a considerable amount of steam, possibly containing some ash, was still being discharged (Anchorage Times, March 8, 1977; Smithsonian Institution, 1977)." Although Miller and others (1998) cite the Anchorage Times, March 8th, as the source of the news article, the article appears in the March 7th edition.
The March 7, 1977, Anchorage Times article states: "A volcanic eruption on Seguam Island in the Aleutian Chain yesterday morning shot smoke and fire hundreds of feet into the air, a U.S. Coast Guard spokesman said this mroning.
"A Coast Guard cutter spotted the eruption shortly after 7 a.m., Anchorage Time, and radioed a report to Coast Guard headquarters in Junear.
"'Fountains' of smoke and fire were steadily being spewed 100 to 200 feet into the air from the mouth of the voclano, Captain Hal Olson, commander of the cutter Mellon, reported.
"'The flow divides into two tongues - the smaller moving southerly approximately 1/2-mile long and 1/4 mile wide, the large moving steadily about 1 1/2 miles long by 1/2 mile wide,' Olson reported.
"Two vents, or mouths, of the volcano were erupting, with lava and black smoke flowing from both.
"No earthquakes occurred from the eruption although it was reported to be one of the largest in the area, a spokesman for the Palmer Observatory said.
"Seismic stations on Adak and Nikolski Islands, located on each side of Seguam Island, did not pick up readings leading scientists to believe little or no seismic action followed the eruption.
"Seguam Island, about 160 miles east of Adak Island, is uninhabited. The island is about 15 miles long and five miles wide.
"The 37-foot cutter, normally based in Honolulu, was on fisheries patrol off the Aleutian Islands."
Jicha and Singer (2006) measure the present volume of material erupted during the 1977 eruptions as 0.06 cubic km (6x10^7 cubic m).

Pyre Peak 1992/12

December 27, 1992 — December 30, 1992

From McGimsey and others (1995): "On December 27, 1992, U.S. Coast Guard pilots reported an ash cloud to 1200 m above Pyre Peak and extending 24 km north. Intermittent, localized bursts of ash rising 100-200 m and ash accumulation on the south flank were observed on December 30. The vent was confirmed to be a satellite cone located 1.5 km south of Pyre Peak at the north end of a fissure that produced lava fountains in 1977. The activity apparently subsided soon thereafter. No subsequent activity was reported until May 1993."

Pyre Peak 1993/5

May 28, 1993 — August 19, 1993

From Miller and others (1998): "Explosive ash eruptions along with a lava flow were reported by Coast Guard observers from July 31, 1993 through August 19, 1993; ash clouds were reported to altitudes of 2,500 m at times during this interval."
However, eruptive activity was reported from Seguam as early as May 28. 1993, and this may be the start of this eruption (Smithsonian Institution, 1993): "A small ash burst, rising through clouds near Pyre Peak, was reported by the U.S. Coast Guard on 28 May. A plume to 3 km altitude was reported on 2 June by the NWS, but it is not known if the plume contained ash."

Summary of earthquake activity and deformation at Mount Spurr from June 1, 2023 to March 28, 2025. Top panel shows the Aviation Color Code at Mount Spurr. Second panel plots the total number of earthquakes located per week within 25 km of Mount Spurr. The gray circles in the third panel show the magnitude of the largest earthquake recorded each week. The bottom panel shows daily positions at GNSS station SPBG with respect to a reference location in cm. Since the beginning of 2024 this station has moved more than 6 cm away from Mount Spurr.

View of the Mount Spurr steam plume on the evening of March 26, 2025, from the Glen Alps Overlook in Anchorage, Alaska. Steam and gas emissions form a prominent plume from the summit crater. Steaming from a small fumarole on the north flank is visible in closeup images. Crater Peak is shadowed on the south flank of the volcano.

Steam plume billowing out of the summit of Mount Spurr, seen from Anchorage 80 miles away. Time-lapse is from 19:00 to 21:30 AKDT, displayed 500 times faster than real time.

Crater Peak as viewed during an overflight of Mount Spurr summit and Crater Peak on March 21, 2025. Weak steaming was observed from fumaroles inside the crater.

Video of Crater Peak from an overflight of Mount Spurr on March 21, 2025. There are weak fumaroles (steam vents) along the snow-free ridges on the west side of the crater within Crater Peak.

AVO staff are captured on Spurr webcam CKT after cleaning snow off the camera during fieldwork on March 21, 2025. Other equipment at monitoring station SBCR and Mount Spurr are visible in the background.

Video from an AVO overflight of the summit of Mount Spurr on March 21, 2025. Fumaroles within the summit crater are producing a steam and gas plume and have melted surrounding snow and ice to form a crater lake. Much of the lake surface is covered in snow and ice, and the exposed water is discolored from compounds in the volcanic gasses.

Steam vents (fumaroles) on two partially snow-free ridges on the west side of the Crater Peak vent as viewed during an AVO overflight on March 21, 2025.

Snow-free and weakly steaming fumaroles inside of the Crater Peak vent as viewed during an overflight of Mount Spurr summit and Crater Peak on March 21, 2025. The toe of a recent small avalanche from the eastern wall of Crater Peak is seen in the foreground.

An AVO geologist uses a thermal camera (FLIR T1020) during an overflight to measure the temperatures of the newly reactivated fumaroles within Crater Peak on March 21, 2025.

Steam vents (fumaroles) on a ridge on the west side of the Crater Peak vent as viewed during an AVO overflight on March 21, 2025.

An AVO scientist measures the composition of the volcanic gasses coming out of newly reactivated fumaroles within the Crater Peak vent at Mount Spurr on March 21, 2025. Two instruments are sticking out the window, one is a hose that is sampling the outside air for analysis and one is a probe that measures temperature and relative humidity.

Before an eruption

Ashfall & Preparedness Information

During and After an Eruption

Ash Forecasting

Mathematical models developed by the USGS forecast various aspects of how a volcanic ash plume will interact with wind—where, how high, and how fast ash particles will be transported in the atmosphere, as well as where ash will fall out and accumulate on the ground. AVO runs these models when a volcano is restless by assuming a reasonable hypothetical eruption, to provide a pre-eruptive forecast of areas likely to be affected. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available.

Ashfall thickness forecast

The Ash3d model was developed by the USGS to forecast how a volcanic ash plume will interact with wind and where ash will fall out and accumulate on the ground. AVO runs these models twice daily when a volcano is restless by assuming a reasonable hypothetical eruption altitude and duration. The map shows the model results of ashfall thickness for areas that are likely to be affected, if one were to occur. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available, and these plots will be automatically updated. The National Weather Service Anchorage Forecast Office will issue the official ashfall warning product and post them at weather.gov/afc

Ashfall Start Time

This map shows the modeled estimate of the time it would take for ashfall to begin following an eruption. It corresponds to the ashfall thickness forecast map shown above. This map uses the start time of either the twice-daily hypothetical model runs (time shown in the legend) or the actual eruption start time (if one were to occur). In the case of an actual eruption, the National Weather Service Anchorage Forecast Office will issue the official ashfall warning product that includes the ashfall start time and post them at weather.gov/afc

Ashfall likelihood maps

These maps show the areas that could experience ashfall if an explosive eruption of Mount Spurr were to occur. They show the area of “disruptive” ashfall where at least 100 g/m2 (0.3 oz/ft2) of ash could fall (in color), and a larger area where “perceptible” ashfall of 10 g/m2 (0.03 oz/ft2) could occur (as a dashed line).

Three ashfall likelihood maps are produced daily and provide ashfall forecasts for the current day, the next day, and two days later. These are intended to be used for situational awareness and planning purposes. Each map is based on 48 simulations using the USGS Ash3d model. The simulations vary the eruption start time and eruption cloud altitude using observations of three explosive events at Spurr in 1992 as guidance.

“High likelihood” areas are impacted in 66-100% of the simulations, “Medium Likelihood” areas are impacted in 33-66% of the simulations (25–50%); and “Low Likelihood” areas are impacted in 5-33% of the simulations.

What is the relationship between mass and deposit thickness?

The Ash3d model determines areas affected based on ashfall in units of mass per unit area (g/m2 or oz/ft2). Two ash deposits with the same mass per unit area but different densities will have different thickness: a denser ash deposit will be thinner than a less dense deposit of the same mass per unit area. We will not know the density until after an eruption starts and ashfall occurs, so a range of deposit thicknesses are given.

What can I expect from “disruptive” ash?

The “disruptive” ashfall maps show how likely it is for areas to receive at least 100 g/m2 (0.3 oz/ft2) of ash given the forecasted wind conditions. This threshold for potentially disruptive ashfall is based on case studies from around the world. A mass per unit area of 100 g/m2 corresponds to an ash deposit that is approximately 0.1 to 1 mm (0.004–0.04 inches) thick, depending on the deposit density and whether it has been compacted by rain or snow.

It is important to note that the threshold is a minimum value. The ash deposit from an actual eruption would likely be much greater closer to the volcano, and in populated areas. For example, the ash deposit in Anchorage from the August 1992 eruption of Mount Spurr was 10-20 times greater than the threshold used in the maps. Ashfall in Anchorage from the 1953 eruption was about twice that of 1992, and in both cases it was sufficient to block out the sun for several hours across Cook Inlet, turning day into “night”.

In general, the thicker the ashfall, the more problems it will cause on the ground, especially in populated areas. The 1992 ashfall closed the Anchorage airport for almost a day until it could be cleared, and presented air quality problems for months as the ash was resuspended by winds and vehicle traffic. A variety of other impacts are possible including abrasive damage to mechanical equipment, and disruptions to electrical service. Detailed information and photos of ashfall impacts and how to mitigate them is available through the Volcanic Ashfall Impacts Working Group.

What can I expect from “perceptible” ash?

The area of “perceptible” ashfall is shown on the maps using a dashed line and shows the area where 10 g/m2 (0.03 oz/ft2) of ashfall was in 5% of model runs. A mass per unit area of 10 g/m2 corresponds to an ash deposit that is at least 0.01 mm (0.0004 inches) thick, depending on the deposit density and whether it has been compacted by rain or snow. This amount of ash is noticeable to the naked eye and will be most apparent on surfaces that have a different color than the ash or are reflective and smooth, like snow or cars.
