KVERT reported that a thermal anomaly over Karymsky was identified in satellite images during 24-31 July.
Strombolian and Vulcanian explosions during 27-30 July produced ash plumes that rose to 3-3.5 km (10,000-11,500 ft) a.s.l.
and drifted 250 km SW and SE.
The Aviation Color Code remained at Orange (the second highest level on a four-color scale).
