"Volcanic eruption plumes and subsequent drifting ash clouds from North Pacific volcanoes have caused delays in flight operations nationwide and substantial damage to aircraft and equipment. Volcanic ash also has caused difficulties in Alaskan communities, ranging from property damage to health hazards. This operating plan provides an overview of multiple agency integrated operations in response to the threat of volcanic ash affecting Alaska, and an agency-by-agency description of roles and responsibilities in such events. A cohesive, well coordinated response will result in the flow of timely and consistent information to those at risk."

Since 1988, the Alaska Volcano Observatory (AVO) has been monitoring volcanic activity across the state, conducting scientific research on volcanic processes, producing volcano-hazard assessments, and informing both the public and emergency managers of volcanic unrest. Below are some examples of the activity at Alaska's volcanoes that have held the attention of AVO staff.

The Alaska Volcano Observatory was founded in 1988 after the eruptions at Cook Inlet's Augustine Volcano in 1986 caused significant disruptions to passenger jet travel to Anchorage and south-central Alaska. In 1986 few tools were available for scientists in Alaska to warn safety officials and the public of the size and location of Augustine's ash clouds that threatened to damage passenger aircraft. Residents of Homer and other coastal cities in south-central Alaska faced significant uncertainty about what would happen next at the volcano and what kind of risks their communities faced from Augustine Volcano.

Along the 450-km-long stretch of the Aleutian volcanic arc from Great Sitkin to Kiska Islands, edifice failure and submarine debris-avalanche deposition have occurred at seven of ten Quaternary volcanic centers. Reconnaissance geologic studies have identified subaerial evidence for large-scale prehistoric collapse events at five of the centers (Great Sitkin, Kanaga, Tanaga, Gareloi, and Segula). Side-scan sonar data collected in the 1980s by GLORIA surveys reveal a hummocky seafloor fabric north of several islands, notably Great Sitkin, Kanaga, Bobrof, Gareloi, Segula, and Kiska, suggestive of landslide debris. Simrad EM300 multibeam sonar data, acquired in 2005, show that these areas consist of discrete large blocks strewn across the seafloor, supporting the landslide interpretation from the GLORIA data. A debris-avalanche deposit north of Kiska Island (177.6° E, 52.1° N) was fully mapped by EM300 multibeam revealing a hummocky surface that extends 40 km from the north flank of the volcano and covers an area of 380 km2. A 24-channel seismic reflection profile across the longitudinal axis of the deposit reveals a several hundredmeter- thick chaotic unit that appears to have incised into well-bedded sediment, with only a few tens of meters of surface relief.

"NVEWS - a National Volcano Early Warning System - is being formulated by the Consortium of U.S. Volcano Observatories (CUSVO) to establish a proactive, fully integrated, national-scale monitoring effort that ensures the most threatening volcanoes in the United States are properly monitored in advance of the onset of unrest and at levels commensurate with the threats posed. Volcanic threat is the combination of hazards (the destructive natural phenomena produced by a volcano) and exposure (people and property at risk from the hazards)."

"Recent explosive eruptions at some of Alaska's 41 historically active volcanoes have significantly affected air traffic over the North Pacific, as well as Alaska's oil, power, and fishing industries and local communities. Since its founding in the late 1980s, the Alaska Volcano Observatory (AVO) has installed new monitoring networks and used satellite data to track activity at Alaska's volcanoes, providing timely warnings and monitoring of frequent eruptions to the aviation industry and the general public. To minimize impacts from future eruptions, scientists at AVO continue to assess volcano hazards and to expand monitoring networks."

"Major and trace element compositions and Sr, Nd, Pb, and Hf isotope ratios of Aleutian island arc lavas from Kanaga, Roundhead, Seguam, and Shishaldin volcanoes provide constraints on the composition and origin of the material transferred from the subducted slab to the mantle wedge. 40Ar/39Ar dating indicates that the lavas erupted mainly during the last 400 kyr. Along-arc geochemical and isotopic variations are consistent with variable degrees of fluid input to the mantle wedge."

"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)."

Several high alumina basalts from the Aleutian volcanic centers of Cold Bay and Kanaga Island contain large (up to 1.5 cm diameter) megacrysts of sector-zoned augite. The megacrysts are invariably euhedral with well developed {001}, {010} and {111} forms. All crystals display concentric bands that are rich in mineral and glass inclusions.

Alaska hosts within its borders over 80 major volcanic centers that have erupted during Holocene time (<10,000 years). At least 29 of these volcanic centers (table 1) had historical eruptions and 12 additional volcanic centers may have had historical eruptions. Historical in Alaska generally means the period since 1760 when explorers, travelers, and inhabitants kept written records. These 41 volcanic centers have been the source for >265 eruptions reported from Alaska volcanoes.

"During 1996, the Alaska Volcano Observatory (AVO) responded to eruptive activity, anomalous seismicity, or suspected volcanic activity at 10 of the approximately 40 active volcanic centers in the state of Alaska. These events included a dramatic volcano-seismic crisis at Akutan and a vigorous strombolian eruption at Pavlof. As part of a formal role in KVERT (the Kamchatkan Volcano Eruption Response Team; Miller and Kurianov, 1993), AVO staff also disseminated information about eruptions and other volcanic unrest at six volcanic centers on the Kamchatka Peninsula and in the Kurile Islands."

During 1993, the Alaska Volcano Observatory (AVO) responded to episodes of eruptive activity or false alarms at nine volcanic centers in the state of Alaska. Additionally, as part of a formal role in KVERT (the Kamchatkan Volcano Eruption Response Team), AVO staff also responded to eruptions on the Kamchatka Peninsula, details of which are summarized in Miller and Kirianov (1993). In 1993, AVO maintained seismic instrumentation networks on four volcanoes of the Cook Inlet region--Spurr, Redoubt, Iliamna, and Augustine--and two stations at Dutton Volcano near King Cove on the Alaska Peninsula. Other routine elements of AVO's volcano monitoring program in Alaska include periodic airborne measurement of volcanic SO2 and CO2 at Cook Inlet volcanoes (Doukas, 1995) and maintenance of a lightning detection system in Cook Inlet (Paskievitch and others, 1995).

"The Alaska Volcano Observatory (AVO) responded to eruptive activity or suspected volcanic activity (SVA) at 6 volcanic centers in 1995 (tables 1, 2): Mount Martin (Katmai Group), Mount Veniaminof, Shishaldin, Makushin, Kliuchef/Korovin, and Kanaga. Of these, AVO has a realtime, continuously recording seismic network only at the Katmai Group. The remaining unmonitored volcanoes are located in sparsely populated and uninhabited areas of the Alaska Peninsula and the Aleutian Islands. For these volcanoes, the AVO monitoring program relies mainly on pilot reports, observations of local residents and ship crews, and analysis of satellite images. The phrase "suspected volcanic activity", used to characterize several responses, is an eruption report or report of unusual activity that is subsequently determined to be normal or enhanced fumarolic activity, weather-related phenomena, or a non-volcanic event."

The role of the subducting lithospheric slab in the genesis of mantle-derived (primitive) magmas is investigated through a study of volcanic rocks formed in the tectonically strike-slip&acirc;€“dominated western Aleutian arc. Two types of chemically and petrologically distinctive primitive andesites have been found among the Miocene&acirc;€“ late Pleistocene&acirc;€“age volcanic rocks in the western Aleutians.

The Aleutian Islands and northern Pacific were among the last regions on earth visited by Europeans. Most early explorations were by officials of the Russian government, independent fur traders, and officials of the Russian American Company. Consequently, reports of these early expeditions are in obscure Russian (or German) publications. After the United States purchased Alaska in 1867, exploration and surveying was conducted by various government agencies, chiefly the U.S. Coast Survey and the Coast and Geodetic Survey.

"The majority of the active volcanoes of the present time are situated on the borders of the Pacific Ocean. They form a mighty chain, which extends from the Tierra del Fuego along the Andes to the Coast and Fairweather ranges of North America; thence crossing over, by means of the Aleutian Islands, to the peninsula of Kamschatka, and going through the Japan and Philippine Islands, it ends in Borneo and Java."

"The list of shocokcs printed in 1887, and those compiled during succeeding years, contained many reported "eruptions" of mountains in the Puget Sound region. For a number of years I made it my business to apply by letter to intelligent observers in that neighborhood to determine whether MOunt Baker and the other mountains had ever certainly been known to be in eruption."

"It is very certain that volcanic activity has existed at numerous points along the northwestern coast of America from the Golden Gate northward in comparatively recent times. Less certainty exists in this newly settled region as to historical outbursts."

"The borders of the Pacific Ocean are studded with volcanoes and the products of volcanic activity. The volcanoes are arranged in crudely arc-shaped groups, and most of the arcs are conves toward the ocean. In addition to the bordering arcs, the Pacific contains many individual volcanic islands and a few non-arcuate groups of volcanic islands, like the Hawaiian Islands. The curving chain of volcanoes from Kiska Island near the western end of the Aleutian Islands to Mt. Spurr on the mainland constitutes one of the Pacific volcanic arcs. This report is concerned with the past activity of the volcanoes of this arc, herein called the Aleutian arc."
