AVO lowered both the Aviation Color Code and the Volcano Alert Level for Davidof to Unassigned on 21 April, noting that the earthquake swarm which began in January had declined in the previous few weeks. It is unknown if the swarm was due to tectonic processes or volcanic unrest. The level “Unassigned” means that there is not sufficient instrumentation on the volcano for AVO to characterize a base level of activity; the closest seismometer was on Little Sitkin (15 km E).

According to AVO the earthquake swarm that began on 24 January in the vicinity at Davidof continued at least through 15 March with a few small earthquakes recorded each day by seismometers on Little Sitkin (15 km E). The rate was variable, though the total number of events was similar to the previous week. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory.

According to AVO the earthquake swarm that began on 24 January in the vicinity at Davidof continued at least through 8 March with a few small earthquakes recorded each day by seismometers on Little Sitkin (15 km E). The earthquakes were shallow (less than 10 km deep) and the largest recorded during the last 7-10 days was a M 3.9. The swarm was either related to tectonic processes or volcanic unrest. The volcano is also monitored by satellite and remote infrasound and lightning networks. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory.

26 January-1 February 2022 Citation IconCite this Report

An earthquake swarm, either related to tectonic processes or volcanic unrest, was recorded in the vicinity of Davidof during 25-26 January. The largest earthquake was a M 4.9 recorded at 1602 on 25 January. AVO raised the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory due to the possibility of escalating volcanic unrest. Small earthquakes were detected during 27 and 29 January-1 February, though at a lower rate. No anomalous activity was visible in partly-to-mostly cloudy satellite and webcams views. A similar earthquake swarm occurred in December 2021.
