OVDAS-SERNAGEOMIN reported that, although cloud cover often prevented observations during 17-22 April, satellite and web camera views of the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, occasionally showed plumes that rose no higher than 400 m above the crater. Incandescence from the crater was observed during 17-18 and 20-21 April. Due to the low level of activity and decreasing seismicity, the Alert Level was lowered to Yellow on 23 April.
