Description
From Miller and others (1998) [1] : "Mount Peulik volcano, a small truncated stratovolcano with a basal diameter of about 10 km, is located just north of the main axis of the Aleutian Range near Becharof Lake on the Alaska Peninsula. The volcano lies west of the axis of a northeast-striking syncline [2] and is built upon Jurassic sedimentary rocks. The volcano partially overlaps the north flank of Ugashik caldera, a small circular structure about 5 km in diameter and of probable late Pleistocene age. A summit crater, about 1.5 km in diameter, has been breached on the west side and is occupied by a dome about 0.5 km in diameter. This dome, and possibly earlier predecessors, were the source the a thick deposit of block-and-ash flows that underlie about 40 square km of the western flank of the volcano. A smaller dome occurs on the east flank at an elevation of 1200 m and was the source of a small block-and-ash flow. Avalanche deposits representing an earlier sector collapse (Miller, unpublished data) underlie an area of 75 square km northwest of the volcano. Flows from flank eruptions of Peulik cover about 8 square km north of the volcano extending as far as Becharof Lake."Name Origin
"Ugashik-Peulik volcanic center" is an informal name. The principal peaks in the center are Mount Peulik and Mount Ugashik.

During and After an Eruption
Ash Forecasting
Mathematical models developed by the USGS forecast various aspects of how a volcanic ash plume will interact with wind—where, how high, and how fast ash particles will be transported in the atmosphere, as well as where ash will fall out and accumulate on the ground. AVO runs these models when a volcano is restless by assuming a reasonable hypothetical eruption, to provide a pre-eruptive forecast of areas likely to be affected. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available.

Ashfall thickness forecast
The Ash3d model was developed by the USGS to forecast how a volcanic ash plume will interact with wind and where ash will fall out and accumulate on the ground. AVO runs these models twice daily when a volcano is restless by assuming a reasonable hypothetical eruption altitude and duration. The map shows the model results of ashfall thickness for areas that are likely to be affected, if one were to occur. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available, and these plots will be automatically updated. The National Weather Service Anchorage Forecast Office will issue the official ashfall warning product and post them at weather.gov/afc

Ashfall Forecast
Ashfall Start Time
This map shows the modeled estimate of the time it would take for ashfall to begin following an eruption. It corresponds to the ashfall thickness forecast map shown above. This map uses the start time of either the twice-daily hypothetical model runs (time shown in the legend) or the actual eruption start time (if one were to occur). In the case of an actual eruption, the National Weather Service Anchorage Forecast Office will issue the official ashfall warning product that includes the ashfall start time and post them at weather.gov/afc
