"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.

A methodology to systematically rank volcanic threat was developed as the basis for prioritizing volcanoes for long-term hazards evaluations, monitoring, and mitigation activities.

"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)."

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.

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.

"Quaternary Aleutian volcanism extends for over 2,500 km, from Buldir Island on the west to Mount Hayes on the east (fig. 1). This belt of volcanic activity lies immediately north of the Aleutian trench, a convergent boundary between the North American and Pacific lithospheric plates."

"The Alaska Peninsula and Aleutian Islands form one of the conspicuously arcuate lines of volcanoes that border the Pacific Ocean. The name Aleutian Range is applied to this 1,600 mile long, narrow belt of peaks reaching from Mount Spurr opposite Anchorage to the island of Attu, close to the continent of Asia."

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 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 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."
