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."

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.

Eruptive History

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).

Deformation History

There is no Deformation History data available for Dutton.

Emission History

There is no Emissions History data available for Dutton.
