Kanaga unrest 2014/3

Start: March 26, 2014 [1]

Stop: March 27, 2014 [1]

Event Type: Not an eruption

Event Characteristics:
  • Seismicity with no confirmed eruption [1]

Description: From Cameron and others, 2017: "A short lived swarm 5 km (3.1 mi) east-northeast of Kanaga Volcano began on March 26, 2014, with 24 located earthquakes. The number and size of earthquake doubled the next day, and included earthquakes with magnitudes up to 1.1. On March 27, the swarm started to decrease in numbers and intensity, and by March 29 had ceased altogether. The total swarm encompassed 72 earthquakes large enough to locate. Subsequent satellite observations showed no changes at the summit following this short-lived earthquake swarm. The only other notable observation of Kanaga seismic data was the presence of 2-3 Hz monochromatic signals in late August through early September, which could be a sign of magma moving under the volcano. The Aviation Color Code and Volcano Alert Level remained at GREEN/NORMAL for all of 2014."
