Description

From Miller and others (1998) [1] : "Mount Gareloi, which makes up most of Gareloi Island, is a stratovolcano 10 km by 8 km in diameter at its base with two summits, separated by a narrow saddle. Two small glaciers extend northwest and southeast from the saddle. The northern, slightly higher peak is on the southern rim of a crater about 300 m across, which contains several active fumaroles. Thirteen younger craters, from 80 to 1600 m in diameter, are aligned along a south-southeast trending fissure that extends from strandline to the southern summit. These craters formed during a major explosive eruption in 1929 that also produced four blocky lava flows (unit Ql), and a blanket of glassy andesitic tuff that covers an area roughly 2.5 x 5 km on the volcano's southeast flank [2] .
"The intercalated lava flows and pyroclastic debris that make up Gareloi volcano were produced during two periods of activity separated by an extended interval of quiescence and erosion. Lava flows range from 1 m to more than 6 m in thickness; some flows of the older sequence appear to have originated from flank vents rather than from the summit. Some valleys cut in older rocks are U-shaped, suggesting that the older series is of late Pleistocene age or older. Rocks of the younger series are relatively undissected; many appear to have been erupted form at or near the summit crater. Craters formed during the 1929 eruptions are probably only partly of phreatic origin; erupted material included essential, pumiceous glass, and reddened scoria. Lava flows that erupted in 1929 emerged at elevations below 600 m. In 1949, one crater at an elevation of 900 m, contained a small, milky blue-green lake, which suggests that acid fumaroles were still active in the crater at that time (Coats, 1959 [2] , p. 253)."

Name Origin

Mount Gareloi is named after Gareloi Island. Gareloi Island's name was published as "O[strov] Goreloi," or "Goreloi Island" by Lt. Sarychev (1826), from the Russian word for "burnt" or "burning." According to Captain Tebenkov (1852), its Unangam Tunuu name was "Anangusik." The name "Gareloi" appeared on U.S. and British maps prior to 1902 (Orth, 1971).

Sanford 1981/4

April 11, 1981

An Associated Press story carried by both the LA Times and the New York times reported that a huge rockslide on Mt. Sanford on April 11, 1981, had been previously mistaken for a volcanic eruption. The text of the story (Associated Press, 1981) is as follows: "A huge landslide on Mount Sanford was mistaken for a volcanic eruption by nearby residents and airline pilots passing overhead yesterday, a University of Alaska scientist says. The slide on the mountain's sheer south face exposed layers of old, loose ash that strong updrafts pushed into a huge plume-shaped cloud, Carl Benson, a member of the university's Geophysical Institute, said after flying over the 16,237-foot peak yesterday. The landslide occurred in a sparsely populated area, and there were no reports of injury or damage."

Sanford 1993/4

April 5, 1993 — April 8, 1993

From Neal and others (1996): "Ground observers in Glennallen reported unusual white cloud formations over Mount Sanford on April 5 and 6, 1993. Another report on April 8, 1993, indicated that the mountain 'was steaming' from low on the east or south side (there were conflicting reports) and the resultant cloud was boiling up the flank to an estimated 5,000 ft (1,524 m) over the top of the peak. This level of apparent activity was more than this observer had noted in 21 years of viewing the volcano. Given the history of rock and ice falls from the shear south flank of the mountain and the fact that the phenomenon was short lived, AVO concluded that the observations were probably related to a large avalanche(s) or to unusual orographically induced weather clouds. No mention of the event was made in the AVO weekly update."

Sanford 1994/9

September 30, 1994

From Neal and others (1995): "On September 30, [1994], the National Weather Service (NWS) contacted AVO with a pilot report of a steam plume over Mount Sanford. AVO contacted the local flight service station in Gulkana and discussed the observation. Given the clear weather conditions at the time, the transience of the plume, and the history of large gravity slides at Mount Sanford, it was concluded that the observation was probably related to a large avalanche. No mention of this event was made in the AVO weekly update on volcanic activity in Alaska."

Sanford 1997/9

September 30, 1997

From McGimsey and Wallace (1999): "A Copper Center resident reported a large steam cloud rising from the southwest face of Mt. Sanford on September 30, 1997. The cloud persisted throughout the afternoon before dissipating. Based on previous similar activity, AVO staff concluded that the cloud resulted from avalanching or debris fall from the southwest face."

Sanford 2009/3

March 18, 2009 — March 19, 2009

From McGimsey and others (2014): "On March 18 and 19, 2009, local Copper River Basin residents observed a large, unusual cloud emanating from the summit of Mount Sanford volcano (figs. 2-4). AVO was alerted on March 19 because the cloud had persisted for more than 24 hours and some residents were concerned that the cloud indicated volcanic activity. The cloud was reported to extend for more than 50 km (30 mi). The plume was visible March 19 on a webcam located at the High Frequency Active Auroral Research Program (HAARP) facility, 29 km (18 mi) north of Glennallen, Alaska, but the view was 'all clear' at Sanford from this camera on March 20. From the vantage point of most residents of the Copper River Basin, this cloud appeared to be a feature unique to Sanford; however, AVO remote sensing specialists examining satellite images of the region reported that this was one of several orographic clouds streaming off the higher mountain peaks in the area. AVO issued an Information Statement on March 20 to report and explain the observations."

Loading

Sanford 2010/3

March 15, 2010 — October 20, 2010

From Neal and others (2014): "On March 23, a consulting geologist working in the area reported seeing a 'good size plume' from Sanford on 2 night. A number of Copper River Valley residents shared photographs of Sanford from March 15 when a dramatic looking plume emated from the southern flank and summit of the volcano.
"A similar cloud was reported on October 20 by Pete Dalton, District Ranger for the National Park Service, stationed at the Gulkana Airport. According to Pete Dalton, the plume rose about 2000 to 3000 ft above the summit. AVO received multiple calls regarding the October 20 plume, which appeared to originate from several points on the near-vertical, rocky southern face of the volcano. A towering vapor cloud emanating from the steep rocky face of this volcano has been reported before (McGimsey and others, 1999) and may be related to rock and ice-fall activity, solar warming of the rock and ice face, or a combination of processes. No features related to volcanic heat sources have been documented on Mount Sanford; however, no comprehensive thermal survey has been done."

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
