The Sernageomin OVDAS reports an LP earthquake, associated with the dynamics of internal fluids at the Nevados de Chillan complex this June 6, at 4:17 am local; the hypocentre is located 6 km deep.

The corresponding explosive activity on the surface is characterized by a plume of ash, incandescent materials and gases rising 760 meters above the point of emission, with a dispersion towards the northeast, and projections on the upper flanks of the volcano.

The Amarilla alert level is maintained.
