Description

From Wood and Kienle (1990) [1] : "The Edgecumbe volcanic field on southern Kruzof Island is on the North American plate 10-15 km inboard of the Queen Charlotte-Fairweather transform fault. The Edgecumbe volcanic field is dominated by the symmetric stratovolcano of Mount Edgecumbe and the domes and crater of adjacent Crater Ridge. Mount Edgecumbe was named by Captain James Cook in 1778. The basal shield comprises ~35 cubic km and consists of basalt, basaltic andesite, and andesite lava flows and breccias. The composite cone of Mount Edgecumbe is dominantly of andesite composition and has a volume of ~3.5 cubic km. The low-silica rhyolite domes of Crater Ridge also contain ~3.5 cubic km of magma.
"The latest significant eruptive activity was postglacial and produced voluminous pyroclastic deposits (7.6 cubic km dense-rock equivalent). The main geomorphic features of the Edgecumbe volcanic field were formed during this activity and include basaltic andesite scoria cones, a crater explosively reamed from the Crater Ridge domes during eruptions of rhyolitic pyroclastic flows, and eruption of andesite and dacite tephra during dome emplacement and crater formation on the Mount Edgecumbe cone. Tephra deposits produced by the late Pleistocene-early Holocene activity of the Edgecumbe volcanic field have been found as far away as Juneau and Lituya Bay, 200 km to the north. Vents active during the pyroclastic eruptions have a northeast-southwest alignment that probably marks a regional fissure."

Name Origin

Mount Edgecumbe was named in 1778 by Captain James Cook, "probably after Mt. Edgecumbe at the entrance of Plymouth Harbor, England, or possibly after George, the first Earl of Edgecumbe. The name was adopted by Vancouver" (Wagner, 1937). This feature was also called "Montana de San Jacinto," or "Saint Jacinto Mountain," on August 16, 1775, by Don Juan de la Bodega y Quadra, "in honor of the saint whose day it was" (Wagner, 1937). Lt. Sarychev (1826) called it "Gora Svataya Lazarya," or "Saint Lazarus Mountain (Orth, 1971).

Edgecumbe unrest 2018

April 11, 2022

AVO issued an Information Statement on April 13, 2022, for Mount Edgecumbe, stating "A swarm of earthquakes has been detected in the vicinity of Mount Edgecumbe volcano, beginning at about 2 am AKDT on Monday, April 11, 2022. There have been hundreds of small quakes in the swarm, though the large majority are too small to locate. The National Earthquake Information Center reported that one of the largest earthquakes in the swarm occurred at 11:04 AKDT on April 11, with a magnitude of 2.8 at 10 km depth. The Alaska Earthquake Center reported another earthquake occurred at 3:44 pm AKDT on April 11, with a magnitude of 2.1 and depth of 4 km. As of this morning, the swarm continues, though the rate of earthquakes has declined over the past 24 hours.
"The cause of this earthquake swarm is currently unknown. This swarm may be associated with volcanic processes, regional tectonic activity, or a combination of sources. AVO does not have local seismic instruments in the area, and the closest station is in Sitka, 24 km (15 miles) to the east of the volcano.
"Retrospective analysis of earthquake data in the area shows that a small number of earthquakes started occurring under Edgecumbe in 2020. This week's activity is unusual in the number of events, however."
AVO issued a following information statement on Friday, April 22, 2022, stating "A swarm of earthquakes was detected in the vicinity of Mount Edgecumbe volcano beginning on Monday, April 11, 2022. There were hundreds of small quakes in the swarm, though the large majority were too small to locate. Over the past few days, earthquake activity has declined and is currently at background levels.
"The recent swarm inspired an in-depth analysis of the last 7.5 years of ground deformation detectable with radar satellite data. Analysis of these data from recent years reveals a broad area, about 17 km (10.5 miles) in diameter, of surface uplift centered about 2.5 km (1.5 miles) to the east of Mt Edgecumbe. This uplift began in August 2018 and has been continuing to the present at a rate of up to 8.7 cm/yr (3.4 in/yr) in the center of the deforming area. Deformation has been constant since 2018, and there has not been an increase with the recent earthquake activity. The total deformation since 2018 is about 27 cm (10.6 inches). A figure showing the deformation can be seen here: www.avo.alaska.edu/images/imag…
"Retrospective analysis of earthquake data in the area of Mount Edgecumbe shows that a small number of earthquakes started occurring under the volcano in 2020. The recent earthquake activity that started on April 11 was unusual in having a greater number of events, however. The earthquakes detected under the volcano since 2020 are all M3.0 or smaller. Note that only the largest of the earthquakes can be located by regional seismic networks; hundreds of very small additional events have been detected, but not located. A map showing earthquake locations in the area, including those occurring on regional faults, can be found here: www.avo.alaska.edu/images/imag…
"There have been no visual changes, surface temperature changes, or gas emissions observed.
"The coincidence of earthquakes and ground deformation in time and location suggests that these signals are likely due to the movement of magma beneath Mount Edgecumbe, as opposed to tectonic activity. Initial modeling of the deformation signal shows that it is consistent with an intrusion of new material (magma) at about 5 km (3.1 miles) below sea level. The earthquakes likely are caused by stresses in the crust due to this intrusion and the substantial uplift that it is causing.
"Intrusions of new magma under volcanoes do not always result in volcanic eruptions. The deformation and earthquake activity at Edgecumbe may cease with no eruption occurring. If the magma rises closer to the surface, this would lead to changes in the deformation pattern and an increase in earthquake activity. Therefore, it is very likely that if an eruption were to occur it would be preceded by additional signals that would allow advance warning.
"There is no local volcano monitoring network at Edgecumbe. The closest seismic station is in Sitka, 24 km (15 miles) to the east of the volcano and is operated by the National Tsunami Warning Center. Updated satellite radar observations become available on weekly timescales.
"AVO has begun plans to add to current monitoring capabilities, possibly by adding instruments closer to the volcano. In the meantime, we are monitoring Edgecumbe using existing regional seismic stations and satellite data."
