Start:

January 5, 2013

Observed

Seismicity with no confirmed eruption:

Description: From Dixon and others (2015): "Following the M=7.5 Queen Charlotte earthquake in southeast Alaska on January 5, 2013, the seismograph network on Akutan Volcano recorded episodes of phase modulated tectonic tremor. Other possible earthquake-triggered seismicity was noted at nearby Westdahl and within the Katmai volcanic cluster. AVO internal log entries periodically noted tremor at Akutan, with tectonic tremor as the most probable origin. Short sequences of low-frequency earthquakes were located on February 8, May 29, and September 13, with a small swarm of volcanic-tectonic events reported on July 12. The Aviation Color Code and Volcano Alert Level remained at GREEN/NORMAL throughout the year."
