At Nevados de Chillan, the seismicity of the past 24 hours is marked by volcano-tectonic earthquakes, the most energetic located 3.4 km northwest of the active crater and 3.2 km deep, LP and VLP earthquakes, and tremor.

Emissions of gases and particles have been episodic; during the night, the explosions projected glowing materials around the crater.

The alert level remains in Naranja.
