The Alaska Earthquake Information Center located a moderate earthquake that occurred on Thursday, August 7th at 10:30 AM AKDT in the Andreanof Islands region of Alaska. This earthquake had a preliminary magnitude of 5.8 and was located at a depth of about 4 miles. This event was felt in Unalaska. No reports of this event causing damage have been received at this time. This earthquake is associated with an ongoing seismic swarm in the vicinity of  volcano Kasatochi that started on August 6, 2008. Distance to nearby locations:  49 miles ENE of Adak and 398 miles WSW of Dutch Harbor.

Alaska Volcano Observatory
Volcanic Activity Notice
Kasatochi Volcano - Issued: Wednesday, August 6, 2008, 7:17 PM AKDT
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: ADVISORY
Volcanic Activity Summary: Over the past 12 hours earthquake activity in the greater vicinity of Kasatochi volcano has increased rapidly. Earthquakes are poorly located, and it is possible that the earthquakes are associated with submarine activity. A US Fish and Wildlife Service field crew on Kasatochi Island has reported continual small tremors over the past several days. AVO is elevating the color code at Kasatochi to YELLOW due to the possibility that these earthquakes may result from magma movement toward the surface. The swarm-like character of the seismicity suggests that the activity may be related to the intrusion of magma which may or may not culminate in eruptive activity.
Remarks: Kasatochi Island represents the emergent summit of a predominantly submarine volcano composed of basaltic and andesitic flows and pyroclastics. The island consists of a single, undissected cone with a central lake-filled crater about 0.75 km in diameter. A maximum height of 314 m is on the southern crater rim; elevation of the lake is less than about 60 m. Kasatochi Island is at the northern end of a 15-km-long, 6-km-wide submarine ridge that is normal to the trend of the Andreanof Islands. Water depths along the ridge are less than 90 m; if Kasatochi is constructed entirely on the ridge, the total height of the volcanic pile is only a little more than 400 m.

Okmok Volcano
Current Aviation Color Code: ORANGE
Current Volcano Alert Level: WATCH
Please see http://www.avo.alaska.edu/activity/Okmok.php for current information.

Ashfall Advisory
The National Weather Service in Anchorage has issued an ashfall advisory for the Eastern Aleutians including Unalaska and Nikolski. The ashfall advisory is now in effect until 12 pm AKDT Friday.  Seismic activity indicates that volcanic ash emissions continue from Okmok Volcano. Ash is moving west to northwest from the volcano. This
movement is expected to shift west to southwest, Friday. Light ashfall is expected across Umnak Island.
