Description: On August 11, 2021, the Alaska Volcano Observatory raised the Aviation Color Code and Alert Level at the Atka volcanic complex to YELLOW/ADVISORY after detecting an increased number of small, shallow earthquakes over the past day. These earthquakes have been located 3 to 6 km (1.9 to 3.7 miles) deep and around 7 km (4.3 miles) southwest of Korovin Volcano. The earthquakes represent an increase from background seismic activity, but may not necessarily lead to an eruption.
