During an overflight of Villarrica on 19 November, SERNAGEOMIN scientists observed a cone on the crater floor with an incandescent vent at its center, containing a lava lake. Deposits of ejected material were seen on the flanks. That same day a 75-minute-long series of volcano-tectonic earthquakes began at 1940.
There was a total of 21 events located 7.8 km ESE of the crater. The largest event, a M 1.6, occurred at 2007 at a depth of 2.5 km based on data collection and analysis of Red Nacional de Vigilancia Volcánica (RNVV) and Observatorio Volcanológico de los Andes del Sur (OVDAS), respectively. The Alert Level remained at Yellow (the second lowest level on a four-color scale) and the public was warned that material could be ejected within 500 m of the crater.
ONEMI remained the Alert Level Yellow (the middle level on a three-color scale) for the municipalities of Villarrica, Pucón (16 km N), Curarrehue, and the commune of Panguipulli.
