A thermal anomaly over Karymsky was identified in satellite images during 8-9 October.
On 19 October KVERT lowered the Aviation Color Code to Yellow (the second lowest level on a four-color scale), noting that only gas-and-steam emissions persisted after the last ash explosions were recorded on 25 September.
On 20 October explosions generated ash plumes that rose as high as 4 km (13,100 ft) a.s.l.
and drifted almost 90 km ENE.
KVERT raised the Aviation Color Code to Orange.
