Background

The mostly ice-covered Mount Martin stratovolcano lies at the SW end of the Katmai volcano cluster in Katmai National Park. The volcano was named for George C. Martin, the first person to visit and describe the Katmai area after the 1912 eruption. Mount Martin is capped by a 300-m-wide summit crater, which is ice-free because of an almost-constant steam plume and contains a shallow acidic lake. The edifice of Martin volcano overlies glaciated lava flows of the adjacent mid- to late-Pleistocene Alagoshak volcano on the WSW and was constructed entirely during the Holocene. Mount Martin consists of a small fragmental cone that was the source of ten thick overlapping blocky dacitic lava flows, largely uneroded by glaciers, that descend 10 km to the NW, cover 31 sq km, and form about 95% of the eruptive volume of the volcano. Two reports of historical eruptions that originated from uncertain sources were attributed by Muller et al. (1954) to Martin.

Increased seismicity occurred at Martin during 8 January until at least 15 January. About 300 earthquakes were recorded during 2 days, in contrast to the background rate of ~25 earthquakes per month since the seismic network was installed in 1996. AVO increased the Concern Color Code to Yellow. ... Read all
