| (7) Notice Number: | |
| (8) Volcano Location: | N 55 deg 11 min W 162 deg 16 min |
| (9) Area: | Alaska Peninsula |
| (10) Summit Elevation: | 4833 ft (1473 m) |
| (11) Volcanic Activity Summary: | AVO can no longer seismically monitor Mount Dutton volcano due to the lack of a functioning seismic network there. As a result, AVO is unable to (1) assess whether Dutton may be building towards an eruption and (2) quickly confirm or dismiss reports of activity at the volcano. Because Dutton is no longer seismically monitored, it will move from volcano alert level Normal and aviation color code Green to "unassigned." As at other volcanoes without real-time seismic networks, AVO will continue to use satellite data, regional infrasound, lightning, and reports from pilots and ground observers to detect signs of eruptive activity. |

| (14) Remarks: | Mount Dutton is located near the tip of the Alaska Peninsula and lies jointly within the Izembek Wilderness Area and the Alaska Peninsula Wildlife Refuge. Dutton is a snow- and ice-covered stratovlocano which rises to an elevation of 4833 feet. Although it has no historic eruptive activity, intense earthquake swarms occurred at the volcano in 1984 and 1988. Dutton is located 14 km (9 miles) north of King Cove and 30 km (19 miles) east of Cold Bay. |
