Description
From Miller and others (1998)
[1]
: "Mount Martin is located near the center of a high (>1400 m) ridge of altered basement rocks that extends more than 12 km, west-southwest form Mount Mageik (Riehle and others, 1987). A crater, approximately 300 m in diameter and breached on its southeast side, occurs high on the east side of the summit cone. The crater is the site of intense fumarolic activity and steam emission, and contains an ephemeral crater lake. The summit cone and the voluminous lava-flow field, which fill the upper valley of Angle Creek northwest of the volcano, which are of Holocene age. This flow-field, which erupted from a vent low on the north flank of the summit cone, covers approximately 31 square km and has volume in excess of 5 cubic km. Martin's extent has previously been overestimated because the young volcano lies adjacent to the glaciated remnants of a mid-Pleistocene andesitic edifice (Alagogshak volcano)."
Name Origin
R.F. Griggs named Mount Martin in 1919, after George C. Martin of the U.S. Geological Survey, who wrote the first authoritative report of the 1912 eruption of Novarupta and Katmai (Orth, 1971).

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

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
