07/1988 (SEAN 13:07) Earthquake swarm

On 10 July, a swarm of small shallow earthquakes began SW of Mt. Dutton. Epicenters gradually migrated NW underneath the mountain's SW flank. The events were similar to a smaller swarm that occurred in 1984. On 15 July and 8 August, days of peak activity, earthquakes (M<=3.8) were felt in the King Cove and Cold Bay areas, ~13 km S and 28 km W of Mt. Dutton, respectively. No harmonic tremor or B-type events have been recorded, and geologists have been unable to determine whether the seismicity is related to magma migration or tectonic movement. During reconnaissance field investigations on 25 and 26 July, T. Miller observed no evidence of gas emission, melting snow, or other changes to the edifice, and no historical volcanic activity has been documented. Holocene activity is indicated by unglaciated pyroclastic deposits on the E flank, debris avalanches on the S flank, and a dome on the NE flank. No surface faults have been mapped with trends similar to current seismicity. Lamont-Doherty's pre-existing regional seismic network and two supplemental seismic stations recently installed on the volcano's slopes by the AVO were recording daily earthquake activity as of mid-August.

08/1988 (SEAN 13:08) Seismicity drops but remains in background

"Seismicity near Mt. Dutton has continued at a low level since the last day of high activity on 8 August. Earthquakes have been high-frequency in character (i.e. not low-frequency volcanic events) and the best-located hypocenters lay at shallow depths (1-10 km) beneath the volcano's SE flank. Figure 1 shows three pulses of high activity followed by a few events/day through 4 September. This level of activity is still much higher than the background rate of a few events/year that existed before the swarm started in July."

The Mount Dutton volcanic center east of Cold Bay near the tip of the Alaska Peninsula consists of a glacier-covered, 1506-m-high central lava dome complex. Early andesitic lava flows and late-stage dacitic lava domes have been partially removed by one or more Holocene edifice collapses about 5100-6800 years ago. This created debris avalanches that traveled to the west and to the south, reaching Belkofski Bay. The important regional fishing center of King Cove lies less than 15 km from the volcano, and the village's airstrip is built on top of the southern avalanche deposit. A steep-sided complex of lava domes forms the summit of the volcano, and young block-and-ash flow deposits extend to the east. Two small unglaciated lava domes on the NE flank 3.5 km from the summit are also of Holocene age. Major earthquake swarms near the volcano were recorded in 1984-85 and 1988.

The Global Volcanism Program is not aware of any Holocene eruptions from Dutton. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Dutton page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Dutton.

Snow-capped Mount Dutton volcano, seen here from the NE with the wall of Emmons Lake caldera in the foreground, is a small stratovolcano near the tip of the Alaska Peninsula. Successive dacitic lava domes overlying andesitic lava flows form the summit. Collapse of the summit during the Holocene produced debris avalanches that traveled to the west and also reached Belkofski Bay to the south. No historical eruptions are known, although earthquake swarms were recorded in 1984-85 and 1988.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
