Copahue emits volcanic ash

State: Chile | Coordinates: -37.85, -71.17 | Eruption: ash-steam cloud

Chile’s Copahue volcano became active on Tuesday, emitting a cloud of ash vapor. In addition, red glow can be seen at the crater at night. SERNAGEOMIN registers weak tremor and writes on Twitter that the volcano often showed a similar behavior in the winter months (in the southern hemisphere it is winter right now). The reason given for this is that a reduction in the size of the crater lake releases a vent that otherwise operates covertly underwater.
