Aniakchak Volcano

 

The Volcanic Alert Level for the volcano was raised to "yellow", as an increased number of earthquakes beneath the volcano have been recorded.
The location of earthquakes appears to occur in a SW-NE pattern along the southern and eastern caldera rim. The background seismic activity at the volcano has mostly been characterized by deep (>15 km or 9.3 miles), long-period events that have occurred at a rate of approx. four earthquakes per month. Quakes have become more intense and shallower since October 2022 by now, occurring at less than 9 km depth. The earthquake rate has risen since 31 January with dozens of quakes per day, including M 3.7 event on 17 February.
There are no expectations of impending and sudden eruption to happen as the similar activity might occur from time to time. The AVO observatory suggests extra shallow seismic activity and other signs of unrest, such as gas emissions, elevated surface temperatures etc.
