Ash emission from Calbuco this evening
Starting from 23:30 local time last night (23 April), activity at the volcano has again increased. The volcano started to produce more or less continuous small to moderate ash emissions, that have been reaching up to 2 km height and drifted mainly northeast.

This increase in activity has also been accompanied by volcanic tremor in the seismic signals, Sernageomin reported.
Ash emissions have been occurring from from several vents at and near the summit of the volcano, the most intense ones originating from the crater of the cinder cone on the 1961 lava dome.
