Preliminary volcano-hazard assessment for the Emmons Lake Volcanic Center, Alaska 4180

The Emmons Lake volcanic center is a large stratovolcano complex on the Alaska Peninsula near Cold Bay, Alaska. The volcanic center includes several ice- and snow-clad volcanoes within a nested caldera structure that hosts Emmons Lake and truncates a shield-like ancestral Mount Emmons edifice. From northeast to southwest, the main stratovolcanoes of the center are: Pavlof Sister, Pavlof, Little Pavlof, Double Crater, Mount Hague, and Mount Emmons. Several small cinder cones and vents are located on the floor of the caldera and on the south flank of Pavlof Volcano. Pavlof Volcano, in the northeastern part of the center, is the most historically active volcano in Alaska (Miller and others, 1998) and eruptions of Pavlof pose the greatest hazards to the region.

Emmons Lake Volcanic Center, Alaska Peninsula: source of the late Wisconsin Dawson tephra, Yukon Territory, Canada 3403

"The Emmons Lake Volcanic Center on the Alaska Peninsula of southwestern Alaska is the site of at least two rhyolitic caldera-forming eruptions (C1 and C2) of late Quaternary age that are possibly the largest of the numerous caldera-forming eruptions known in the Aleutian arc. The deposits produced by these eruptions are widespread (eruptive volumes of >50 km3 each), and their association with Quaternary glacial and eolian deposits on the Alaska Peninsula and elsewhere in Alaska and northwestern Canada enhances the likelihood of establishing geochronological control on Quaternary stratigraphic records in this region. The pyroclastic deposits associated with the second caldera-forming eruption (C2) consist of loose, granular, airfall and pumice-flow deposits that extend for tens of kilometres beyond Emmons Lake caldera, reaching both the Bering Sea and Pacific Ocean coastlines north and south of the caldera."

Preliminary volcano-hazard assessment for Great Sitkin Volcano, Alaska 3493

"Great Sitkin Volcano is a composite andesitic stratovolcano on Great Sitkin Island, a small (14 x 16 km), circular volcanic island in the western Aleutian Islands of Alaska. Great Sitkin Island is located about 35 kilometers northeast of the community of Adak on Adak Island and 130 kilometers west of the community of Atka on Atka Island. Great Sitkin Volcano is an active volcano and has erupted at least eight times in the past 250 years (Miller and others, 1998). The most recent eruption in 1974 caused minor ash fall on the flanks of the volcano and resulted in the emplacement of a lava dome in the summit crater."

The 1999 eruption of Shishaldin Volcano, Alaska: monitoring a distant eruption 2968

Shishaldin Volcano, in the central Aleutian volcanic arc, became seismically restless during the summer of 1998. Increasing unrest was monitored using a newly installed seismic network, weather satellites, and rare local visual observations. The unrest culminated in large eruptions on 19 April and 22-23 April 1999. The opening phase of the 19 April eruption produced a sub-Plinian column that rose to 16 km before rapidly dissipating. About 80 min into the 19 April event we infer that the eruption style transitioned to vigorous Strombolian fountaining. Exceptionally vigorous seismic tremor heralded the 23 April eruption, which produced a large thermal anomaly observable by satellite, but only a modest, 6-km-high plume.

Preliminary volcano-hazard assessment for Hayes volcano, Alaska 2935

"Hayes Volcano is an ice- and snow-mantled, deeply eroded volcanic massif located in the northern Tordrillo Mountains of the north-central Cook Inlet region about 135 kilometers northwest of Anchorage, Alaska. Hayes Volcano consists of a glacially dissected, poorly exposed cluster of lava domes. No historical eruptions of Hayes Volcano are known, and the last period of major eruptive activity occurred within a time interval of 4,400 to 3,600 years ago. During this period, explosive Plinian-style eruptions occurred that dispersed volcanic ash over large areas of interior, south-central, and southeastern Alaska. Pyroclastic flows produced during these eruptions descended Hayes Glacier and entered the Hayes River drainage. The pyroclastic flows initiated volcanic debris flows or lahars that flowed down the Hayes River, into the Skwentna River, and probably reached the Yentna River about 110 kilometers downstream from the volcano. The last major eruptive period of Hayes Volcano may have spanned about 200 years, and at least one of the eruptions during this interval was possibly the largest eruption of any volcano in the Cook Inlet region in the past 10,000 years."

The Kamchatkan Volcanic Eruption Response Team (KVERT) 3389

"Russia's Kamchatka Peninsula is home to 29 active volcanoes, including 7 snow-capped stratocones more than 10,000 ft (3,000 m) high. Several eruptions each year in Kamchatka produce ash clouds that threaten the safety of air travel across the North Pacific, including travel between the United States and Russia and Japan. The Kamchatkan Volcanic Eruption Response Team (KVERT), created in 1993 through a cooperative effort of Russian and U.S. scientists, monitors the volcanoes of Kamchatka to provide warnings and rapid reporting of eruptions."

Preliminary volcano-hazard assessment for Kanaga Volcano, Alaska 3494

"Kanaga Volcano is a steep-sided, symmetrical, cone-shaped, 1307 meter high, andesitic stratovolcano on the north end of Kanaga Island in the western Aleutian Islands of Alaska. Kanaga Island is an elongated, lowrelief (except for the volcano) island, located about 35 kilometers west of the community of Adak on Adak Island and is part of the Andreanof Islands Group of islands. Kanaga Volcano is one of the 41 historically active volcanoes in Alaska and has erupted numerous times in the past 11,000 years, including at least 10 eruptions in the past 250 years (Miller and others, 1998). The most recent eruption occurred in 1993-95 and caused minor ash fall on Adak Island and produced blocky aa lava flows that reached the sea on the northwest and west sides of the volcano (Neal and others, 1995)."

Preliminary volcano-hazard assessment for Aniakchak Volcano, Alaska 718

"Aniakchak is an active volcano located on the Alaska Peninsula 670 kilometers southwest of Anchorage. The volcano consists of a dramatic, 10-kilometer-diameter, 0.5 to 1.0-kilometer-deep caldera that formed during a catastrophic eruption 3,500 years ago. Since then, at least a dozen separate vents within the caldera have erupted, often explosively, to produce lava flows and widespread tephra (ash) deposits. The most recent eruption at Aniakchak occurred in 1931 and was one of the largest explosive eruptions in Alaska in the last 100 years. Although Aniakchak volcano presently shows no signs of unrest, explosive and nonexplosive eruptions will occur in the future. Awareness of the hazards posed by future eruptions is a key factor in minimizing impact."

Preliminary volcano-hazard assessment for Iliamna Volcano, Alaska 642

"Iliamna Volcano is a 3,053-meter-high, ice- and snow-covered stratovolcano in the southwestern Cook Inlet region about 225 kilometers southwest of Anchorage and about 100 kilometers northwest of Homer. Historical eruptions of Iliamna Volcano have not been positively documented; however, the volcano regularly emits steam and gas, and small, shallow earthquakes are often detected beneath the summit area. The most recent eruptions of the volcano occurred about 300 years ago, and possibly as recently as 90-140 years ago. Prehistoric eruptions have generated plumes of volcanic ash, pyroclastic flows, and lahars that extended to the volcano flanks and beyond. Rock avalanches from the summit area have occurred numerous times in the past. These avalanches flowed several kilometers down the flanks and at least two large avalanches transformed to cohesive lahars. The number and distribution of known volcanic ash deposits from Iliamna Volcano indicate that volcanic ash clouds from prehistoric eruptions were significantly less voluminous and probably less common relative to ash clouds generated by eruptions of other Cook Inlet volcanoes. Plumes of volcanic ash from Iliamna Volcano would be a major hazard to jet aircraft using Anchorage International Airport and other local airports, and depending on wind direction, could drift at least as far as the Kenai Peninsula and beyond. Ashfall from future eruptions could disrupt oil and gas operations and shipping activities in Cook Inlet. Because Iliamna Volcano has not erupted for several hundred years, a future eruption could involve significant amounts of ice and snow that could lead to the formation of large lahars and downstream flooding."

Preliminary volcano-hazard assessment for Redoubt Volcano, Alaska 713

"Redoubt Volcano is a stratovolcano located within a few hundred kilometers of more than half of the population of Alaska. This volcano has erupted explosively at least six times since historical observations began in 1778. The most recent eruption occurred in 1989-90 and similar eruptions can be expected in the future. The early part of the 1989-90 eruption was characterized by explosive emission of substantial volumes of volcanic ash to altitudes greater than 12 kilometers above sea level and widespread flooding of the Drift River valley. Later, the eruption became less violent, as developing lava domes collapsed, forming short-lived pyroclastic flows associated with low-level ash emission. Clouds of volcanic ash had significant effects on air travel as they drifted across Alaska, over Canada, and over parts of the conterminous United States causing damage to jet aircraft. Economic hardships were encountered by the people of south-central Alaska as a result of ash fallout. Based on new information gained from studies of the 1989-90 eruption, an updated assessment of the principal volcanic hazards is now possible. Volcanic hazards from a future eruption of Redoubt Volcano require public awareness and planning so that risks to life and property are reduced as much as possible."

Volcanic ash - Danger to aircraft in the North Pacific 2114

"The world's busy air traffic corridors pass over hundreds of volcanoes capable of sudden, explosive eruptions. In the United States alone, aircraft carry many thousands of passengers and millions of dollars of cargo over volcanoes each day. Volcanic ash can be a serious hazard to aviation even thousands of miles from an eruption. Airborne ash can diminish visibility, damage flight control systems, and cause jet engines to fail. USGS and other scientists with the Alaska Volcano Observatory are playing a leading role in the international effort to reduce the risk posed to aircraft by volcanic eruptions."

Ballistic showers during Crater Peak eruptions of Mount Spurr volcano, Summer 1992 2128

"Crater Peak vent at Mount Spurr volcano ejected large ballistic blocks and bombs during all three eruptions of 1992. Ballistics flew north during the June 27 eruption, east-southeast during the August 18 eruption, and east during the September 16-17 eruption. The bombfield of the August eruption, which is scattered over an area of at least 12 square kilometers and extends more than 8 km east-southeast of the vent (figs. 1, 2, 3), is the most extensive and accessible bombfield of the 1992 eruptions."

Pyroclastic flows of the 1992 Crater Peak eruptions: distribution and origin 1985

"Crater Peak, a 2,309-m-high satellite cone on the south flank of the Mount Spurr volcanic center 125 km west of Anchorage erupted on June 27, August 18, and the night of September 16-17, 1992 (see Eichelberger and others, this volume) after 39 years of quiescence. The three eruptions were similar in that they each produced vulcanian to subplinian eruption columns as high as 18 km above sea level, formed extensive bomb fields, lasted 3 to 4 hours, erupted pyroclastic material only, had ejecta bulk volumes of 44 to 56 x 106 m3 each (see Eichelberger and others, this volume), and were of andesitic composition."

Preliminary petrology and chemistry of proximal eruptive products: 1992 eruptions of Crater Peak, Mount Spurr volcano, Alaska 2099

"Mount Spurr, Alaska, located approximately 125 km west of Anchorage, is the northernmost historically active volcanic center of the eastern Aleutian arc. Prehistoric Mount Spurr was an andesitic stratovolcano that underwent avalanche caldera formation approximately 10,000 years ago (Nye and Turner, 1990). Following subsequent ash flows, a dacite dome was emplaced in the caldera and now forms the summit of Mount Spurr. Crater Peak, a flank vent, was built in the breach of the southern caldera rim and has been the site of historic volcanism, including the eruptions in 1953 and 1992."

Whole-rock major- and trace-element chemistry of 1992 ejecta from Crater Peak, Mount Spurr volcano, Alaska 2117

"Mount Spurr volcano, 125 km west of Anchorage, is the next-to-last Holocene volcano at the northeastern end of the Aleutian arc. It is about 100 km above the Benioff zone and 500 km from the trench in a direction parallel to the movement between the Pacific and North American plates. The region surrounding Mount Spurr is underlain by a Jurassic to mid-Tertiary granitic batholith, which intrudes Paleozoic to Mesozoic limestone, basalt, and flysch of generally low metamorphic grade (Wilson and others, 1985)."

The 1989-1990 eruptions of Redoubt volcano: an introduction 173

Redoubt Volcano, located on the west side of Cook Inlet in south-central Alaska, erupted explosively on over 20 separate occasions between December 14, 1989 and April 2l, 1990. Fourteen lava domes were emplaced in the summit area, thirteen of which were subsequently destroyed. The eruption caused economic losses estimated at over $160,000,000 making this the second most costly eruption in U.S. history.

Dome growth and destruction during the 1989-1990 eruption of Redoubt volcano 1989

Much of the six-month-long 1989-1990 eruption of Redoubt Volcano consisted of a dome-growth and destructive phase in which 14 short-lived viscous silicic andesite domes were emplaced and 13 subsequently destroyed. The life span of an individual dome ranged from 3 to 21 days and volumes are estimated at 1 X 106 to 30X 10 6 m 3. Magma supply rates to the vent area averaged about 5 X 105 m3/day for most of the dome-building phase and ranged from a high of 2.2X 106 m 3 per day initially to a low of 1.8Ã� 105 m 3 per day at the waning stages of the eruption. The total volume of all domes is estimated to be about 90 Ã� 106 m 3 and may represent as much as 60-70% of the volume for the entire eruption.

Geochemistry of the 1989-1990 eruption of Redoubt Volcano: Part I. Whole-rock major- and trace-element chemistry 2118

The 1989-1990 eruption of Redoubt Volcano produced medium-K calc-alkaline andesite and dacite of limited compositional range (58.2-63.4% SiO2) and entrained quenched andesitic inclusions (55% SIO2) which bear chemical similarities to the rest of the ejecta. The earliest (December 15 ) magmas are pumiceous, often compositionally banded, and the majority is relatively marie ( < 59% SIO2). The most silicic magmas of the eruption are the late December to early January domes (up to 63.4% SIO2). Subsequent magmas formed domes and rare pumices which converge on 60% SIO2.

Geochemistry of the 1989-1990 eruption of Redoubt Volcano: Part II, Evidence from mineral and glass chemistry 2313

Early stages (December 1989) of the 1989-1990 eruption of Redoubt Volcano produced two distinct lavas. Both lavas are high-silica andesites with a narrow range of bulk composition (58-64 wt.%) and similar mineralogies (phenocrysts of plagioclase, hornblende, augite, hypersthene and Fe-Ti oxides in a groundmass of the same phases plus glass). The two lavas are distinguished by groundmass glass compositions, one is dacitic and the other rhyolitic. Sharp boundaries between the two glasses in compositionally banded pumices, lack of extensive coronas on hornblende phenocrysts, and seismic data suggest that a magma-mixing event immediately preceeded the eruption in December 1989.

A postulated new source for the White River Ash, Alaska 1474

"The White River Ash (Lerbekmo and others, 1968), product of two of the most voluminous pyroclastic eruptions in North America in the past 2,000 yr, blankets much of the Yukon Temtory, Canada, and a small part of adjoining eastern Alaska. Lerbekmo and Carnpbell (1969) narrowed the source of the ash to an area northeast of the Mt. Bona-Mt. Churchill massif in the St. Elias Mountains of southern Alaska. Based on indirect evidence, Lerbekmo and Campbell (1969) further suggested that the vent was beneath the Klutlan Glacier, adjacent to a mound of coarse pumice, 16 km northeast of Mt. Bona. Recently discovered pumice and ash deposits and a possible vent structure near the summit of Mt. Churchill suggest an alternate source area."

Geological and seismological evidence of increased explosivity during the 1986 eruptions of Pavlof Volcano, Alaska 169

We present results of study of the best-documented eruptions of Pavlof volcano in historic time. The 1986 eruptions were mostly Strombolian in character; a strong initial phase may have been Vulcanian. The 1986 activity erupted at least 8 x 106 m 3 of feldspar- phyric basaltic andesite lava (SiO2 = 53-54%), and a comparable volume of wind-borne tephra. During the course of the eruption, 5300 explosion earthquakes occurred, the largest of which was equivalent to an ML=2.5 earthquake.
