On 12 May, OVDAS-SERNAGEOMIN reported that a slight increase in activity from Villarrica during April led to a change in the Alert Level from Green Level 1 to Green Level 2.
April's activity was characterized by increased seismicity, a rise in the lava lake level, more vigorous fumarolic activity, and more frequent incandescence at night.
According to the Projecto Observación Visual Volcán Villarrica (POVI), the spattering lava lake was about 100 m below the crater rim on 10 May.
