Copahue (Chile-Argentina) – Report for 30 June-6 July 2021 – NEW

SERNAGEOMIN and SEGEMAR reported increased activity at Copahue, beginning with minor, sporadic increases in tremor first detected at the end of May. During 30 June-2 July tremor was elevated and volume of water in the crater lake decreased significantly. Coincidently crater incandescence was visible in nighttime webcam views and gas emissions increased. Residents reported volcanic gas odors. Increased gas-and-steam emissions during 1100-1400 on 2 July contained minor amounts of ash that left visible deposits on the SE and ENE flanks. The Alert Level remained at Green (the lowest level on a four-color scale).
