"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.

Mt Veniaminof is a large active stratovolcano located on the Alaska Peninsula (56.28 N, 1598 W). We present results of the first geophysical survey of the icefield that fills much of the 10km x 8km caldera that was most recently modified during the last major eruption roughly 3700 BP. The subglacial topography and ice volume are derived from an 8MHz radio-echo sounding survey conducted in July 2005. Prominent internal reflectors are assumed to be isochronal ash/acid deposits related to local eruptions. Accumulation rates and basal melt rates are calculated using a Nye onedimensional steady-state accumulation model applied at a location that approximates an ice divide and calibrated by matching internal reflectors with published records of recent local volcanic eruptions. The model yields order of magnitude estimates of the accumulation rate of 4myr^-1 water equivalent and 2myr^-1 of basal melt.

Mt. Veniaminof, Alaska Peninsula, is a stratovolcano with a summit ice-filled caldera containing a small intracaldera cone and active vent. From January 2 to February 21, 2005, Mt. Veniaminof erupted. The eruption was characterized by numerous small ash emissions (VEI 0 to 1) and accompanied by low-frequency earthquake activity and volcanic tremor.We have performed spectral analyses of the seismic signals in order to characterize them and to constrain their source.

This report presents gas emission rates from data collected during numerous airborne plume-measurement flights at Alaskan volcanoes since 1995. These flights began in about 1990 as means to establish baseline values of volcanic gas emissions during periods of quiescence and to identify anomalous levels of degassing that might signal the beginning of unrest. The primary goal was to make systematic measurements at the major volcanic centers around the Cook Inlet on at least an annual basis, and more frequently during periods of unrest and eruption.

Mount Veniaminof volcano, Alaska Peninsula, provides an opportunity to relate Quaternary volcanic rocks to a coeval intrusive complex. Veniaminof erupted tholeiitic basalt through dacite in the past ~260 k.y. Gabbro, diorite, and miarolitic granodiorite blocks, ejected 3700 14C yr B.P. in the most recent caldera-forming eruption, are fragments of a shallow intrusive complex of cumulate mush and segregated vapor-saturated residual melts.

"Volcano seismology is a relatively young science that encompasses the study of seismic signals originated at volcanoes and makes use of theory and methods from traditional earthquake seismology to model the likely complex volcanic structure. Progress in volcano seismology in recent decades has been achieved largely because of improvements in instrumentation (e.g. Broadband seismometers, multiparameter stations, permanent GPS stations, borehole instruments) and increase in computing capabilities (e.g. Faster computers with large storage capacity)."

"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)."

The Alaska Volcano Observatory (AVO) tracks activity at the more than 40 historically active volcanoes of the Aleutian Arc (fig. 1). As of December 31, 2002, 24 of these volcanoes are monitored with short-period seismometer networks (fig. 2). AVO's monitoring program also includes daily analysis of satellite imagery supported by occasional over flights and compilation of pilot reports,observations of local residents, and observations of mariners. In 2002, AVO responded to eruptive activity or suspect volcanic activity at 6 volcanic centers in Alaska - Wrangell, the Katmai Group, Veniaminof, Shishaldin, Emmons Lake (Hague), and Great Sitkin volcanoes (fig. 1; tables 1, 2).

The Alaska Volcano Observatory (AVO) monitors the more than 40 historically active volcanoes of the Aleutian Arc. Of these, 24 were considered monitored in real time with short-period seismic instrument networks as of the end of 2003 (figs. 1, 2) (Dixon and others, 2004). The AVO core monitoring program also includes daily analysis of satellite imagery, observation over flights, and compilation of pilot reports and reports from local residents and mariners. In 2003, AVO responded to eruptive activity or suspected volcanic activity at or near 10 volcanic centers (fig. 1; tables 1, 2): Wrangell, Redoubt, Iliamna, Augustine, Mageik, Veniaminof, Pavlof, Emmons Lake (Hague), Shishaldin, and Akutan volcanoes. In addition to responding to eruptive activity at Alaska volcanoes, AVO assisted in the disseminaation of information for the Kamchatka Volcanic Eruption Response Team (KVERT) about the 2003 activity of 6 Russian volcanoes: Sheveluch, Klyuchevskoy, Bezymianny, Karymsky, Alaid, and Chikurachki volcanoes (fig. 22; tables 3, 4). Due to prevailing wind directions, erupting Kamchatkan, Kurile Island, and Alaskan volcanoes pose a serious potential threat to aircraft in the North Pacific (fig. 3).

2004 began quietly in Alaska, continuing a trend of little volcanic unrest that has persisted for several years. On January 9, AVO announced the beginning of formal seismic monitoring of Okmok Volcano following an extended period of calibration and improvement of the seismic network installed initially in 2002-2003. Gareloi and Tanaga volcanoes in the western Aleutians were added to the list of seismically monitored volcanoes in early June following determination of background seismicity. During the remainder of the year, AVO responded to volcanic unrest at three volcanoes in Alaska-Mount Spurr, Veniaminof, and Shishaldin.

Airborne ash probability distribution (AAPD) maps have been generated to show the distribution of airborne volcanic ash in the North Pacific (NOPAC) region by simulating volcanic eruption clouds from 22 of the 100 most historically active volcanoes in the region. The PUFF ash-dispersion model was run daily using archived wind field data between 1994-1995 and 1997-2001 for low and high aircraft flight levels. Subsequent statistics are generated representing the distribution of simulated airborne ash at 6- and 24-h intervals, defining the regions most likely to contain airborne ash and the direction and distance a volcanic ash cloud may propagate from a given volcano. The AAPD maps show the extent of ash from a given volcano can encompass all of Alaska, most of the North Pacific Ocean, portions of northwestern North America, regions as far south as 358N, regions over the western Arctic Ocean, and portions of eastern Russia.

"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."

"The Alaska Volcano Observatory (AVO) monitors 41 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on daily analysis of satellite images, pilot reports, and observations of local residents and ship's crews. In 1999, AVO responded to eruptive activity or suspect volcanic activity at 7 volcanic centers: Wrangell, Shrub mud volcano, Iliamna, Veniaminof, Pavlof, Shishaldin, and Vsevidof volcanoes. Of these, in 1999, AVO had real-time, continuously recording seismic networks at Iliamna, and Shishaldin. The phrase "suspect volcanic activity" (SVA), 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 Mw 7.9 Denali fault earthquake ruptured segments of the Susitna Glacier, Denali, and Totschunda faults in central Alaska, providing a unique opportunity to look for intermediate-term (weeks to months) responses of active volcanoes to shaking from a large earthquake. The Alaska Volcano Observatory (AVO) monitors 24 volcanoes with seismograph networks. We examined one station per volcano. Digitally-filtered data for the period four weeks before to four weeks after the mainshock were plotted at a standard scale. Mt. Wrangell, the closest volcano to the epicenter (247 km), had a background rate of 16 events/day. For the following 30 days, however, its seismicity rate dropped by 50%. Mt. Veniaminof (1400 km from the epicenter) had a rate of 8 seismic events/day, but suffered a drop in seismicity by 80% after the maishock; this may have lasted for 15 days."

Seismology is an important and effective tool for monitoring volcanoes and forecasting eruptions. In the past 2 decades there have been over 25 successful forecasts.

"Few natural forces are as spectacular and threatening, or have played such a dominant role in shaping the face of the Earth, as erupting volcanoes. Volcanism has built some of the world's greatest mountain ranges, covered vast regions with lava (molten rock at the Earth's surface), and triggered explosive eruptions whose size and power are nearly impossible for us to imagine today. Fortunately, such calamitous eruptions occur infrequently. Of the 50 or so volcanoes that erupt every year, however, a few severely disrupt human activities. Between 1980 and 1990, volcanic activity killed at least 26,000 people and forced nearly 450,000 to flee from their homes."

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 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 Peninsula is a 775-km-long southwestward extension of mainland Alaska (fig. 1). The peninsula is about 225 km wide at the northeast end and narrows to less than 10 km near the southwest end. The southeast side is bordered by rugged mountains that rise sharply out of the Pacific Ocean. Many large bays and fiords cut the southeast shoreline. The northwest side, bordering Bristol Bay, is level and rarely more than 100 m above sea level; the coastline is nearly smooth and is broken by only a few large bays. At least 37 principal volcanic centers dot the length of the peninsula, and at least 30 have erupted during the Holocene (Miller and Richter, 1994). The present Aleutian volcanic arc overlies an early Mesozoic magmatic arc and a middle Tertiary volcanic arc."

"Notes on activities in the Aleutian Islands and in the Volcanoes on the Alaskan Peninsula were published in Volcano Letters Nos. 246 and 357. The year 1931 appears to have brought to a focus the unrest which appeared in several volcanoes in 1929 and 1930 by producing a considerable explosive eruption from Aniakchak Crater on the Peninsual 45 miles NNE from Chignik."

"Aniakchak and Veniaminof craters were discovered by a Geological Survey party under R.H. Sargent in 1922, and W.B. Smith, geologist of the party, entered Aniakchak crater. In a second expedition in 1925 R.S. Knappen was geologist of the party."

The first author to take up the subject of Alaskan volcanos systematically was Constantine Grewingk in 1850. He gathered from all previous accessible sources such as data existed on record, and his work is the classical source of such information.

"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."

"In the latter part of August, 1982, a great volcanic eruption occurred on the peninsula of Alaska, where very little is known of the geography except the ragged coast line, and the summit outline of the mountain mass behind it, as seen from the southward. Published references to the locality, about latitude 56°, and longitued 159° west, are very limited."

"The largest of this group is the island of Atkha. It resembles Oonalashka in shape, but its indentations are less deep and not so easily accessible. Near the north point of the island there is a volcano called the Korovinsky, nearly 5,000 feet in height, and a few miles to the south another rises to almost the same elevation."

"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."
