Akutan reported activity





Event Name : Akutan 2014/7

Start:July 15, 2014 Observed

Seismicity with no confirmed eruption: BibCard
Eruption Type:Not an eruption.

Description: From Cameron and others, 2017: "A series of 34 earthquakes occurred on Akutan volcano on July 15, 2014. Nine of theearthquakes had a magnitude between 1 and 2; the rest were smaller. Following the earthquake swarm, AVO re-analyzed GPS data and concluded that Akutan experienced about 1 cm (0.4 in.) uplift around the time of the seismic swarm. The GPS data clearly show a volcanic inflation signal (outward and upward) with a start date at the beginning of 2014, most likely indicating intrusion of magma (Jeff Freymueller, UAFGI/AVO, written commun., 2014). A second earthquake swarm of 24 earthquakes occurred 5 months later on December 7, including a M2.5 earthquake, 2-3 km (1.2-1.9 mi) south of Akutan. Tectonic tremor was noted throughout 2014, and is typical for the Akutan seismograph network."
