Description

From Miller and others (1998) [1] : "Aniakchak Crater is an ice-free, circular caldera about 10 km in diameter and a maximum of 1 km deep which was first described by Smith (1925) [2] . The pre-caldera cone was built upon a basement of Tertiary sedimentary and volcanic rocks and Jurassic-Cretaceous sedimentary rocks, which are exposed high on the east and south walls of the caldera [3] . The elevation of the caldera rim varies from 1,341 m to 610 m. Surprise Lake, a 3.2-km-long lake in the northeast part of the caldera at an elevation of about 335 m is the source of the Aniakchak River, which flows through a breach in the eastern wall of the caldera. Numerous domes, flows, and cones occupy the interior of the caldera [4] ; the largest cone is Vent Mountain, 2.5 km in diameter and rising 430 m above the floor of the caldera. The pre-caldera cone was built on the west side of a basement high. The cone was deeply dissected by numerous glaciers that cut U-shaped valleys into the slopes before the caldera-forming eruption.
From Bacon and others (2014) [4] : “The oldest recognized postglacial explosive eruption, andesitic Aniakchak I, left nonwelded ignimbrite in valleys below the edifice and fines-poor welded ignimbrite or agglutinated fall deposits high on its flanks between ca. 9,500 and 7,000 years ago. A small caldera may have collapsed at the source of the ignimbrite, likely just west of the present Vent Mountain…Subsequent to Aniakchak I, Plinian eruptions ca. 7,000 14C yr B.P. from a vent northeast of the edifice summit produced the Black Nose Pumice, consisting of a lower unit of rhyodacite lava, pumice fall, and intraplinian welded ignimbrite and an upper unit of dacite pumice fall and northeast flank lava flow. At least 20 additional Holocene eruptions are thought to have occurred before the Aniakchak II caldera-forming event.”
From Miller and others (1999) [1] : "Ash flows from the caldera-forming eruption - 3430 +/- 10 yrs B.P. [5] - reached both the Bering Sea and the Pacific Ocean [6] . They are typically non-welded and fill glacial valleys to a depth of at least 75 m adjacent to the caldera rim. The ash flows were highly mobile, over-running 260-meter-high passes in the Aleutian Range and traveling as far as 50 km from the caldera rim [6] ."
From Bacon and others (2014) [4] : “Postcaldera vents are mainly on the caldera ring-fracture system. The earliest extruded small dacite domes into a deep caldera lake and a lava flow on the northwest flank. Three basaltic andesite-andesite tuff cones were constructed on the eastern caldera floor after catastrophic draining of the lake by ~200 m. Dacite-andesite magmas issued from Vent Mountain and Half Cone starting as early as ~1,000 years ago. Plinian eruption at Half Cone ~400 14C yr B.P. yielded widespread dacite Pink and overlying andesite Brown Pumice fall deposits. Strombolian eruption of basaltic andesite built Blocky Cone after Half Cone and most Vent Mountain activity. The most recent eruption, in 1931, yielded dacite-rhyodacite tephra followed by relatively voluminous andesite tephra and ended with minor basaltic andesite.”

Name Origin

Sargent and Smith (1922) named Aniakchak Crater and Aniakchak peak. The name was probably derived from nearby Aniakchak Bay (Orth, 1971).

Aniakchak Eruption Timeline

Aniakchak 1931/5

May 1, 1931 — June 13, 1931

From Neal and others (2001): "In the last 200 years, Aniakchak volcano is known to have erupted once - during about six weeks in May - June 1931. Documentation of the event is limited; the following summary is derived principally from the writings of University of Santa Clara missionary and explorer Hubbard (1931; Jan 2 and 16, 1932), who visited Aniakchak in 1930 and 1931.
The 1931 eruption was violent, included both explosive and effusive phases, and sent ash at least 600 km north of the volcano. The first sign of activity was noted about 10 a.m. on May 1, 1931, when residents of the former Meshik (now part of Port Heiden) saw a vigorous, white column of steam ascending above the crater. By noon, residents reported ground shaking, rumbling noises, and the beginning of tephra fall from a large, black mushroom cloud, intermittently illuminated by lightning, over the caldera. Cloud height was estimated to be more than 6 km above sea level. Fallout in Meshik in the early stages of eruption included ash and pea- to egg-sized, frothy, black pumice that pelted homes. Radio communications with Chignik and other communities in southwestern Alaska were hampered repeatedly by static caused by ash in the atmosphere (Anchorage Daily Times, 1931; Fairbanks Daily News-Miner, May 4, 1931). Ash fall was noted at Kanakanak (near Dillingham), 225 km north of the volcano [see fig. 2 in original text] (Fairbanks Daily News-Miner, May 2, 1931). Observers describe a constant level of eruption until May 11, when an extremely violent explosion rocked the volcano. Heavy ash fall produced total darkness for several hours near the volcano. As much as several millimeters of black ash accumulated at Chignik, and greater amounts were recorded at Ugashik [see fig. 2 in original text]. Rafts of pumice containing individual fragments as much as 20 cm across reportedly were floating in Bristol Bay west of Meshik. A 10-km-wide swath of black ash and 'almost complete darkness' observed from a boat in Bristol Bay attest to the severity of the fallout (Seward Daily Gateway, May 28, 1931).
After May 11, the eruption apparently diminished in intensity until May 20, when explosions were heard at Ugashik (75 km northeast) and at an unspecified location more than 300 km away. Beginning on May 26, intermittent small ash plumes were reported over the caldera and Chignik residents reported 'rumbling' like distant surf in the direction of Aniakchak. Several earthquakes, some described as 'severe,' were felt in Chignik and Hook Bay in late May.
Father Hubbard flew over the volcano on June 10, while the eruption was still in progress. His party first hiked to the caldera on June 13 and discovered moving, blocky lava flows at the bottom of two new explosion pits [see figs. 6A, B in original text]. A third small lava flow issued from a knob slightly above the base of the west caldera wall [see fig. 6C in original text]. Steam explosions had reamed a shallow pit in coarse ash and lapilli that blanketed a lava-flow field inside Half Cone [see fig. 6D in original text]. Although accumulation of fallout was heaviest in the western and northwestern parts of the caldera, nearly all vegetation inside the caldera was destroyed or buried. Three small lakes in the western part of the caldera (Knappen, 1929) were filled completely with ash and lapilli, and Surprise Lake was cloudy with suspended ash. Hubbard also reported dead birds, presumably killed by carbon dioxide that had accumulated in low areas near the vent. The north rim of Vent Mountain's summit crater reportedly was steaming (Regan, 1987)."
"* * * Earthquakes during the 1931 eruption were strong enough to be felt in Chignik, 65 km away, and to destabilize the precipitous caldera walls. Hubbard (Jan. 2. 1932) reported avalanches in progress inside Aniakchak in mid-June. The rock-avalanche lobes that extend from the south wall inside the caldera [see fig. 5 in original text] may have formed in 1931.
"Beyond the caldera rim, fallout from the 1931 eruption affected several hundred thousand square kilometers of southwestern Alaska. As much as 1 to 2 cm of ash may have fallen in Chignik (Fairbanks Daily News-Miner, May 14, 1931). Ash reportedly was about 6 mm thick on Kodiak Island (presumably in the village of Kodiak), in Katmai National Monument2, and on the Nushagak Peninsula, and a fine dusting was reported at Holy Cross, 600 km north of the volcano. Light ash fall was reported also at Squaw Harbor on Unga Island, 140 km southwest of Aniakchak. Reindeer and caribou losses from fallout were reported to be 'heavy' at Nushagak, and dead swans and geese, believed to have died from ash ingestion, were noted at Ugashik (Hubbard, Jan. 2, 1932). From these scattered reports, we constructed a map showing the area most likely to have received noticeable amounts of ash fall [see fig. 7 in original text].
"The volume of material erupted in 1931 is difficult to determine by traditional field methods because of the widespread dispersal of fine ash, much of it over water. In many places, because strong winds and rain have stripped the 1931 deposit completely, original thickness on land is difficult to measure accurately. Furthermore, eyewitness accounts are few and, from our experience, prone to exaggeration. Using limited field measurements and interpretation of written accounts of ash fall during and after the eruption, we estimate the total bulk volume of the 1931 deposits to be about 0.3 to 0.5 cubic km.
"The interaction of erupting magma and abundant water in part explains why the 1931 eruption was explosive. The conclusion that the eruption was hydrovolcanic was based on the presence of accretionary lapilli, as much as several centimeters in diameter (Hubbard, Jan. 2, 1932); rhythmic surge-and-fall deposits, exposed in the walls of the main vent; blocky lithic ejecta; and widely dispersed fine-grained ash. Also, Knappen (1929) noted standing water in the western part of the caldera prior to the eruption. That this shallow ground-water system persists is indicated by the presence of Surprise Lake and by the abundance of springs on the floor in the eastern part of the caldera. Future eruptions may include a similar strong hydrovolcanic component as hot rising magma mixes explosively with water."
Bacon and others (2014) estimate the total volume of erupted products at about 0.9 cubic km, less than 1 percent of which was lava.

Aniakchak 1951/6

June 25, 1951

Reeder (1987) reported that Pilot Everett Skinner observed "an extensive eruption cloud" from Aniakchak on June 25, 1951. This event is generally thought to be a resuspension of ash particles rather than a volcanic eruption.

Aniakchak 2004/12

December 15, 2004 — February 3, 2005

From McGimsey and others (2007): "Beginning in mid-December 2004 and continuing into January 2005, several series of 10-20 low-frequency seismic events showed up on the Aniakchak seismic network. On January 11, 2005, returning form an observation flight over nearby Veniaminof Volcano AVO staff photographed a partially ice-free Surprise Lake wihtin the Aniakchak caldera (see fig. 29 in original text). A thermal anomaly of unknown source was detected in satellite data on February 1-3, 2005. Subsequent analysis and discussion among AVO scientists regarding these phenomena concluded that nothing unusual was likely occurring, and no further activity was noted in succeeding months."

Aniakchak 2008/3

March 8, 2008 — March 14, 2008

Seismometers at Aniakchak Volcano appeared to record anomalous seismicty at Aniakchak during the spring of 2008. Further analysis revealed that the signals were a product of icing on the seismometers, and not of volcanic origin.
From Neal and others (2011): "AVO seismic analysts noted a swarm of seismic events at Aniakchak during routine seismic checks of Alaskan volcanoes on March 8. The activity continued intermittently over the next week with events occurring as frequently as 5-10 per hour. Interpreting the significance of the signals was hampered by the fact that only a single station in the Aniakchak network, ANNW, was operating at the time. AVO increased seismic watch frequency for Aniakchak in response and contemplated organizing a winter-time field visit to restore more of the seismic network.
"Subsequently, an evaluation of historical seismicity at Aniakchak during times of more complete network operation suggested that the anomalous signals were likely weather-related (Katrina Jacobs, AVO/UAFGI, written commun., 2008). Similar swarms had occurred on a number of occasions between 2005 and 2008, but none were typical multi-station volcanic events and all showed a strong correlation with time of day. Years of maintenance efforts at the Aniakchak network documented a strong vulnerability of sites to heavy icing that could have been responsible for the intermittent seismic signals. Based on this, an AVO field response was canceled."

Aniakchak 2009/2

February 27, 2009 — June 3, 2009

From McGimsey and others (2014): "Following several episodes of anomalous seismicity in 2008 (Neal and others, 2011), deep, low-frequency seismic events continued to be recorded at Aniakchak Volcano through the first half of 2009 while the seismic network was still operating. On February 27 and 28, 12 low-frequency events were recorded that had magnitudes of ML 1.0-2.1 and hypocentral depths of about 15-28 km (9.3-17.4 mi), and another sequence of events occurred on March 4 with one locatable low frequency event about 7 km (4.4 mi) depth (Scott Stihler, U.S. Geological Survey, written commun., 2011). Another burst of low-frequency events occurred at Aniakchak on June 3, 2009.
"By September 2009, chronic station outages and data interruption prompted AVO to include Aniakchak in the list of four volcanoes considered for downgrading to UNASSIGNED. On November 17, AVO issued a Volcanic Activity Notice and an Information Statement formally declaring that Aniakchak and three other volcanoes: Veniaminof, Fourpeaked, and Korovin were no longer seismically monitored due to seismic station outages, and thus were changed from volcano alert level NORMAL and Aviation Color Code GREEN to UNASSIGNED. Two seismic stations at Aniakchak became operational by December 8, 209, but would again go out in early 2010. The network would eventually become operational again during the summer of 2010."

Aniakchak 2010/1

January 2010

From Neal and others (2014): "A low-frequency event followed by a short-lived tremor-like signal was recorded January 15, 2010, on station ANPB. There were no other stations recording data to facilitate further analysis; winters are particularly hard on Aniakchak stations and by January 26, all seismic stations were offline. On July 7, after summer maintenance and repair, two stations (ANPB and ANPK) recorded an approximate 15-minute long swarm. Another brief sequence of low-frequency events was recorded on station ANON on August 7 from about 21:20 to 21:28 UTC. From about 21:28 to 21:35 UTC, a signal resembling tremor occurred, although it also could be interpreted as a series of closely spaced, low-frequency events. This signal was picked up by the other five stations in the Aniakchak network.
"On October 14 from about 22:29 to 22:39 UTC, another sequence of low-frequency events occurred in the Aniakchak area. Only one event could be located, about 6 km (4 mi) east-northeast of Vent Mountain, the most prominent intracaldera cone. Another similar although shallower (9.1 km or 5.6 mi), low-frequency sequence also occurred on October 19. This event was located about 2 km (1.2 mi) south-southeast of Vent Mountain with a local magnitude of 0.5.
"Cluster, low-frequency events occurred on November 5, December 16, and from December 22-24. These small, emergent events may have been related to ice processes in the vicinity of the seismic station (H. Buurman, University of Alaska, written commun., 2010)."

Aniakchak 2010/8

August 2010

From McGimsey and others (2014): "In late August 2011, AVO was alerted by Troy Hamon, Chief of Resource Management, Katmai National Park, that the larger of two maar crater lakes on the caldera floor of Aniakchak Volcano had recently drained, leaving a gaping notch in the crater rim. The flood had ravaged the downstream drainage and alluvial fan as well as the upper reaches of the Aniakchak River, which drains Surprise Lake and the eastern caldera floor through The Gates. During September 8-9, 2011, authors Tina Neal and Game McGimsey, accompanied by Troy Hamon (on September 8), visited the site to document and study the activity.
"Aniakchak caldera formed about 3,600 years ago in a colossal eruption (Neal and others, 2001). Subsequent eruptive activity has occurred from many intracaldera vents, including eruptions that formed two maar craters, subsequently filling with water, that are situated on the southeastern caldera floor between the central Vent Mountain cone and the sheer inner east caldera wall. The larger maar is about 450 m (1,476 ft) by 515 m (1,690 ft), as measured rim to rim in Google EarthTM imagery (fig. 3); the smaller maar is 170 m (558 ft) in diameter at the rim. The maars formed subsequent to the draining of a caldera-wide lake, at least 1,000 years before present (BP), but they may be much younger, perhaps less than 400 years old.
"Geological investigations in 1992 documented that a low point on the maar rim was about 10-15 m (33-49 ft) above the lake surface, although higher strand lines were visible in the deposits surrounding the maar, one of which was located nearly at the low point (Neal and others, 2001). On the outboard flank of the maar-rim low-point, a seep - piping through the maar crater wall deposits to the lake - occurred near the base of the flank and formed the headwater for the stream that courses between a prominent lava flow from Vent Mountain and the colluvial slopes extending out from the eastern caldera wall. This stream flows about 1.7 km (1 mi) northward from its source at the maar to the Aniakchak River immediately inboard of The Gates, a prominent notch in the caldera wall through which the river drains the entire caldera.
"The maar breakout flood scoured and excavated the channel and banks of the stream north of the maar, cutting deeply into the colluvial slopes on the eastern side of the drainage. The previously well-vegetated alluvial fan near The Gates was entirely covered by flood deposits up to 1.5 m (4.9 ft) thick. Clumps of vegetation, up to about 1 m (3.3 ft) in length, were strewn on and within the deposit. The Aniakchak River was pressed even more tightly against the northern wall opposite the fan, causing some bank erosion, and the downstream river channel, sand bars, and banks were noticeably disrupted for more than 20 km (12.4 mi) beyond The Gates. The area of the breach on the maar rim was dramatically altered as downcutting progressed until a new base level was established. Discharge through the outflow at the northern end of the maar now approximates inflow at the southern end (primarily at the waterfall.
"Field measurements and observations indicate that the maar lake level declined 4.65 m (15.3 ft) from its recent high stand (determined from photographs taken July 18, 2010), as well as measurements made in the field in September 2011); this high stand was below the low-point on the northern rim where the breach occurred. The volume of water lost was at least 645,000 m3 (844,000 cubic yards), but this represents a minimum volume because there is no way of knowing how much additional water flooded into the maar immediately prior to initiation of the breakout flooding.
"Based on analysis of photographs, weather data, and observations from a local guide, the maar flood likely occurred between late July and late September 2010. Evidence of recent flooding on the southern floor and wall of the caldera, which drain into the maar, suggests that the maar flood was likely caused by the rapid and voluminous influx of water into the maar lake during a period of unusually heavy rainfall. The lake level rose rapidly and the low point on the maar rim may have been reached and spilled over. The increased hydraulic head may have simultaneously initiated failure of the crater wall at that location where groundwater seepage and possibly piping within the mantling deposit was occurring. The heavy precipitation may have further increased saturation of the deposit. Once the breach began, by either rapid downcutting, or structural failure of the wall, or both, rapid release of water occurred, resulting in a short-lived but massive flood down the drainage to - and then down - the Aniakchak River."

From Cameron and others, 2020: "Volcanic activity did not occur at Aniakchak volcano (an informal designation used by AVO to refer to the volcano that comprises Aniakchak Crater and the volcanic features in its vicinity) in 2016, but a magnitude 6.2 earthquake occurred 20 km east-southeast of Aniakchak caldera on April 2. This earthquake was followed by an energetic aftershock sequence, and most earthquakes were located in the upper 20 km of the crust. The earthquake and associated aftershock sequence were thrust events and nonvolcanic, although AVO seismologists closely monitored the activity in case a volcanic event was triggered by the regional earthquake sequence. The Aviation Color Code and Volcano Alert Level remained at GREEN and NORMAL, respectively."

Aniakchak ash resuspension 2021

August 1, 2021 — August 2, 2021

From Orr and others, 2024: "When the landscape near Aniakchak Crater is snow-free, and particularly when the ground has little moisture content, strong winds can pick up ash and create large ash clouds. The wind can then transport this resuspended ash, which can pose a hazard to aviation. On August 1-2, 2021, strong southerly winds entrained and resuspended ash from the region north of Aniakchak Crater and east of Port Heiden before carrying it ~200 km [~120 mi] northward over Bristol Bay. High-resolution satellite views indicated that the event’s source region was north of the caldera at the sparse surface exposures of pyroclastic-flow deposits from the caldera-forming eruption. The drifting ash cloud appeared in imagery from the Geostationary Operational Environmental Satellite for ~18 hours beginning late in the morning on August 1. Groundlevel webcam views from Port Heiden also recorded this resuspended ash. In response, AAWU issued a SIGMET for aviators and AVO issued an Information Statement. AVO received no reports of ashfall at Port Heiden. The Aviation Color Code and Volcano Alert Level remained GREEN and NORMAL for Aniakchak Crater during 2021."

Aniakchak unrest 2023

February 22, 2023 — August 17, 2023

On February 22, 2023, AVO raised the Aviation Color Code and Volcano Alert Level at Aniakchak to YELLOW/ADVISORY, citing increased seismicity. "The number of earthquakes beneath Aniakchak volcano has recently increased and shifted to shallower depths. Due to this increase in seismic activity to above-background levels, the Alaska Volcano Observatory is raising the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY. There have been no signs of unrest in other monitoring data.
Background seismicity at Aniakchak has mostly been characterized by deep (>15 km or 9.3 miles), long-period events occurring at a rate of ~4 earthquakes per month. From October 2022 to present, the rate of earthquakes has been more elevated and characterized by shallower earthquakes at depths less than 9 km (5.6 miles) below sea level. The earthquake rate has further increased since January 31 with dozens of earthquakes detected per day, including a M3.7 earthquake on February 17.
There is no indication that an eruption of Aniakchak is imminent, or that one will occur. Increases in seismic activity have been detected previously at other similar volcanoes, with no subsequent eruptions. We expect additional shallow seismicity and other signs of unrest, such as gas emissions, elevated surface temperatures, and surface deformation to precede any future eruption, if one were to occur. Should activity increase, AVO will issue further notices."
Seismic activity continued at similar rates for a few weeks, then began to slowly decline while remaining above background. However, radar data in March showed that the ground within the central caldera was rising. On April 13, an Information Statement was issued, stating that the earthquake activity and ground uplist suggested that magma was intruding below Aniakchak at 2 to 2.5 mi depth.
Uplift continued into June, though at a slower rate. Earthquake activity declined still further around mid-June, though station outages limited data. The outages were fixed in early July.
In late July, there was a small uptick in seismic activity. However, levels declined again the next week.
In late July to early August, radar data showed no continued uplift of the area.
On August 17, 2023, AVO lowered the color code and alert level to GREEN/NORMAL, stating that earthquake and deformation activity had returned to background levels.
