Description

From Miller and others (1998) [1] : "Trident is an eroded volcanic complex consisting of three stratovolcanoes and numerous domes, as high as 1864 m in elevation, along a northeast-southwest oriented volcanic front on the Alaska Peninsula [2] . A new fragmental cone was built beginning in 1953 at an altitude of 1097 m in an amphitheater on the southwest flank of the southwest peak."

Name Origin

"Trident Volcano" is a descriptive name given by R.F. Griggs in 1916, because of its three prominent peaks (Orth, 1971).

Trident Eruption Timeline

Trident 1913/9

September 1913

During the years 1913 to 1919 (the years of the National Geographic Society expeditions to the Katmai National Monument), Trident Volcano was often observed to be "smoking" or "steaming." Eicher and Rounsefell (1957) report a "lighter" eruption in the Katmai area in September, 1913. This eruption may have occurred at Trident.
However, Hildreth (1983) disbelieves this account: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in 1953 - 1968."

Trident 1949/6

June 1949

From Eicher and Rounsefell (1957): "A few weeks later [after May 19, 1949] nearby Mt. Trident erupted, and it has exhibited sporadic activity almost to the present, although without significant ash outfall."
However, Hildreth (1983) disbelieves this account: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in 1953 - 1968."

Trident 1950/7

July 2, 1950 — August 18, 1950

From Decker (1963): "William J. Nancarrow, the Ranger at Brooks River during 1950, mentions 3 explosive eruptions that may have been from Mt. Trident in his monthly reports for July and August, 1950:
"'On July 2 at 2:02 A.M. a side vent of Knife [Griggs] Peak (or something in line with Knife Peak) let go and a cloud of smoke and dust was observed to rise up to 5000 feet.' He also reports seeing a large cloud of smoke and ash rising up behind the west side of Katolinat as viewed from the Fish and Wildlife Camp on Brooks Lake on August 1, and a cloud of dust from the Valley on August 16 to 18 which cut the visibility to 2 miles and left a very thin layer of ash which 'penetrated to all corners.'" This eruption has been attributed to Trident by Simkin and Siebert (1994).
The Sitka Sentinel mentions in their July 11, 1950 edition that "a new volcano was born last week in the white snows of Knife [Griggs] Mountain near the famed 'Valley of Ten Thousand Smokes.' It was first reported July 2 by a group of fishermen."
However, Hildreth (1983) disbelieves this account: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in 1953 - 1968."

Trident 1951/7

July 7, 1951

From Decker (1963): "Al Kropf, pilot with the U.S. Fish and Wildlife Service, reports ash eruptions from a fissure on the side of Mt. Trident were taking place during his aerial patrols to the Shelikof Straits in 1951. The aerial photographs (137 + 138 V10 VP-61 7-7-51 2252 21,200 NAE) taken on July 7, 1951, clearly show a radial fissure over 3000 feet long extending down the southwest flank of Mt. Trident. Fume was present from one vent along the fracture centered in a 2000 foot diameter patch of ash darker than the 1912 Katmai ash. These aerial photographs also show that no lava flows had taken place prior to July, 1951." However, Hildreth (1983) disbelieves this account: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in 1953 - 1968." The ash could be remobilized tephra from previous eruptions in the Katmai area.

Trident 1953/2

February 1953 — 1974

Mount Trident erupted intermittently from 1953-1974. Some (Miller and others, 1998) consider this period as one eruptive event while others (Simkin and Siebert, 1994) break it up into discrete, separate eruptions. Detailed timelines and observations of the eruptive activity at Mt. Trident during this time can be found in Decker, 1963; Ray, 1967, and Ward and Matumoto, 1967. Synder (1954) gives extremely detailed information about events in 1953 and 1954.
Hildreth and others (2003) summarize the eruption as follows: "Beginning in February 1953, a new andesite-dacite edifice (0.7-cubic km volume) was built at the southwestern margin of the Trident group [see unit tsw, fig. 3, in original text]. Though sometimes referred to informally as 'New Trident,' we have called it Southwest Trident (Hildreth and others, 2000), in anticipation of the day it ceases to be Trident's youngest component. During 2 decades of sporadic explosive activity (Vulcanian type and effusive), a new composite cone covering about 3-square km area was constructed of block-and-ash deposits, scoria, agglutinate, stubby lava lobes, and the intercalated proximal parts of the main lava flows that spread as an apron beyond the cone. The cone grew to an elevation of 4,970 ft (1,515 m) (Global Positioning System measurement by Coombs and others, 2000) on the former site of a 100-m-wide fumarolic pit at about 3,840-ft (1,170 m) elevation on the steep southwest flank of Trident I. Although relief on its south slope exceeds 700 m [see fig. 13 in original text], the new cone thus has a central thickness of only 345 m and a volume of about 0.3 cubic km. At successive stages of cone construction, four blocky leveed lava flows effused from its central vent, in 1953, 1957, and 1958 and during the winter of 1959-60 [see figs. 3, 13 in original text]. Each flow is 25 to 60 m thick and 2.5 to 4 km long, and altogether they add about 0.35 cubic km to the eruptive volume. The cone's summit is today marked by a shallow crater, 350 m wide [see fig. 14 in original text], that was the site of several small ephemeral plugs, which were emplaced after the final lava flow and were repeatedly destroyed by intermittent explosive activity (1960-74).
"Black, rapidly expanding, cauliflower ash clouds rose 6 to 9 km at least 10 times between 1953 and 1974 and possibly 12 km once or twice. Several times during the first month of activity, light ashfall dusted areas as far as 30 to 50 km from the vent, in all sectors. By far the most voluminous fallout appears to have resulted from the initial outburst of February 15, 1953 (Snyder, 1954), which may have been sub-Plinian. A single nongraded scoria-fall layer (5-17 cm thick) deposited during that event is preserved at a few protected sites as far away as Mount Katmai and upper Knife Creek. Sieve data for bulk samples of this layer yield median and maximum particle sizes, respectively, of 6.5 and 100 mm in the saddle 1 km north of the vent, and 2.1 and 20 mm in the saddle 7 km northeast of the vent - between the twin western summits of Mount Katmai. Thin sheets of finer ash that fell during the many smaller subsequent outbursts have been almost entirely removed or reworked by wind and runoff. Abundant ballistic blocks, variously breadcrusted, densely vitrophyric, or scoriaceous, that are scattered as far as 3 km from vent are products of many discrete explosive episodes (none of which were closely observed) distributed over 2 decades. Liberal estimates of total fallout volume yield no more than 0.05 cubic km, contributing less than 10 percent of the total eruptive volume of 0.7+/-0.1 cubic km.
"The period of most frequent observation was from February to September 1953, principally by military reconnaissance aircraft during the early months (Snyder, 1954) and by a U.S. Geological Survey (USGS) party that camped at Knife Creek during the summer (Muller and others, 1954). When the vent was first seen through the cloud layer on the fourth day of activity (Feb. 18, 1953), an effusive lava flow (then already 250 m wide) was upwelling centrally and spreading radially (fig. 15A). Although a fumarolic pit, as much as 40 m deep, was conspicuous at the impending ventsite on aerial photographs taken in 1951 (and had probably been further excavated by the explosive outburst of Feb. 15), any such crater was soon filled and buried by the effusive lava [see fig. 15A in original text], which continued to be extruded and spread slowly throughout the seven months of intermittent observation in 1953. At various times, lava lobes emerged laterally through the chilled carapace at the foot of the pile, or the pile itself 'expanded like a balloon' and extruded lobes by overflow from the vent, or small slumps and slide masses detached from the steep flow margins (Snyder, 1954). By June 1953, the main southerly tongue of lava, ultimately 4.2 km long, had advanced only 1,250 m from the vent. Snyder (1954) estimated the volume of fallout and lava produced by June 17, 1953, at 0.23 to 0.3 cubic km, about a third of the eventual output. During the summer, steady steaming and continued spreading of the lava was punctuated sporadically by steam bursts [see fig. 15B in original text] or occasional 'smoke columns' that rose 1 to 3 km and dusted various proximal sectors with minor additional ashfall (Muller and others, 1954).
"Observations after September 1953 were sporadic and few. A general chronology of major events was compiled by Decker (1963) and augmented by Ray (1967), largely from intermittent National Park Service reports. The 1953 lava flow may not have attained its final dimensions [see fig. 3 in original text] until early 1954 or later. Apparently, no observations were made during eruption and outflow of the lava flows of 1957, 1958, and 1959-60 [see fig. 3 in original text], merely aerial snapshots taken in the summer seasons after the emplacement of each flow. The time of emplacement of the lava flow attributed to the winter of 1959-60 is the least well known, because no photographs are known to have been taken between September 1958 and August 1960. The 1958 lava flow partly overran the 1953 flow [see fig. 3 in original text] and impounded a small lake on upper Mageik Creek that soon filled in with pumiceous alluvium, becoming a mudflat (Ferruginous Flat) now marked by numerous iron-precipitating warm springs.
"Growth of the fragmental cone [see figs. 13, 14 in original text] began only after much or all of the 1953 lava flow [see fig. 15 in original text] had been emplaced. The cone accumulated progressively during the later 1950s, as shown by emergence of the successive lava flows at different levels of the fragmental edifice. National Park Service photographs show that the cone had attained nearly its full height by 1960, although explosive showers of blocks continued to augment the cone until 1974. In addition to the four main lava flows, cone construction included emplacement of several stubby lava lobes limited to its proximal southwest slope [see fig. 3 in original text]. The southeast side of the cone completely buried a 1-km-square-area cirque glacier, with no recognized effects on eruptive behavior or edifice structure, although enhanced steaming may have contributed to the stronger fumarolic emission and alteration on that side of the cone [see fig. 14 in original text]. Explosive ejections of tephra, some involving blowout of plugs and at least one spine, took place from 1960 to 1974, but volumetrically significant eruptions were over by 1963. Numerous sulfurous fumaroles, superheated in the 1960s but below and at the boiling point today, persist on the upper parts of the cone [see fig. 14 in original text]. Dark-gray bouldery debris flows reworked from the pyroclastic deposits have built a proximal fan and thin distal sheets (1-4 m thick) that cap stream terraces for 3 km downstream along Mageik Creek. Some debris flows resulted from the initial February 1953 fallout over snow, and others from avalanching of rubble from the steep slopes of the cone."

Trident 2005/6

June 2005

From McGimsey and others (2007): "AVO Coordinating Scientist John Eichelberger was leading an annual student fieldtrip into the Valley of Ten Thousand Smokes (VTTS) in June 2005 when, from the rim of Trident Volcano, he observed a new crater about 50 m (165 ft) in diameter. Eichelberger has traversed the VTTS for many years and verified that the crater was not present during his 2003 trip; clouds prevented viewing the area of the crater in 2004. Although no anomalous seismicity was noted in the Katmai area in 2003 and 2004, a period of tremor-like signal occurred in the Katmai area on April 27 as noted in the AVO Seismic Logs. No correlation has been determined."

Trident unrest 2022

September 24, 2022 — January 10, 2024

On August 24, 2022, an earthquake swarm began beneath Trident volcano in the Katmai area. The first earthquakes were at deep levels in the crust, around 16 miles below sea level, but progressed upward to about 3 miles beneath the surface over the next five days. Dozens of magnitude 0.7 to 1.9 earthquakes happened each day over this time period, but the rate of earthquakes dropped off somewhat after the 28th. There were also a few periods of volcanic tremor and low-frequency earthquakes.
On September 14, 2022, AVO released an Information Statement about the earthquake activity at Trident, stating that no other signs of unrest had been observed and that the seismic activity was likely caused by movement of magma or magmatic fluids.
After the earthquakes continued into the next month, AVO raised the alert levels to YELLOW/ADVISORY on September 29.
On October 19, 2022, citing that the rate of earthquakes had dropped and seismic tremor had not observed since September 30, 2022, AVO lowered the Aviation Color Code to GREEN and the Volcano Alert Level to NORMAL.
On November 20, there was a magnitude 4.6 quake – this was far larger than most of the quakes in the area.
In late 2022 into January 2023, the rate of earthquakes began to pick up again. There were also more earthquakes occurring under Mount Katmai to the east, and under Martin and Mageik volcanoes to the west, though the largest number of earthquakes continued to be beneath Trident, as well as periods of tremor.
On January 11, 2023, AVO released an information statement for Katmai, Trident, Martin, and Mageik volcanoes, noting this more elevated activity.
On February 22, 2023, AVO again raised the Aviation Color Code and Volcano Alert Level at Trident to YELLOW/WATCH, stating that earthquakes were continuing to occurr at about 10 per day. The notice also stated that because of the tremor observed beneath Trident and the initial swarm there, the unrest in the broader Katmai region was likely, though not certain, because of magma or magmatic fluid movement beneath Trident.
In May 2023, AVO began detecting a marked increase in low-frequency earthquakes—in addition to regular earthquakes—at shallow and deep levels in the region between Trident and Novarupta, which lies 3 miles to the northwest. These types of earthquakes often indicate the movement of magma or magmatic fluids within the Earth’s crust. The deep low-frequency earthquakes were often accompanied by longer-duration bursts of continuous tremor, indicating deep fluid movement.
In June, satellite radar data taken in newly snow-free conditions was compared to data taken in the fall, which showed that Trident Volcano had inflated slightly, with the ground uplifted by about 2 inches, especially on the southern flank.
On July 25, 2023, AVO released another Information Statement about this activity, noting that earthquakes also continued to occur around Mount Katmai and Martin and Mageik volcanoes, but AVO continued to believe this was likely a secondary effect of magma/magmatic fluid intrusion beneath Trident.
After July, earthquake activity remained elevated, and deep low-frequency earthquakes and periods of tremor continued. In September AVO noted that there was an increase in the rate of earthquakes very deep in the crust (greater than 9 miles down), as well as some minor additional ground deformation.
Beginning in early October rates of earthquake activity declined somewhat, especially deeper earthquakes. AVO noted that this might indicate a decline in magma/magmatic fluid activity beneath Trident.
Seismicity remained slightly elevated in December.
In the first week of January, AVO noted that while earthquakes were still occurring, their rate was now approaching the typical or "background" state for the Katmai area. Due to this, AVO lowered the alert levels back to GREEN/NORMAL on January 10, 2024.

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
