The Sernageomin informs of an emission of particulate materials to the Volcanic Complex Planchon-Peteroa this 7 November at 10:24 local (1324 GMT); the plume reached 1,000 meters of altitude, dispersing towards the ESE. The episode did not give significant precursor seismic signals.
Emissions continued during the day.
Due to the context, it fits into the current alert level: Amarillo technical alert.
In its October situation, the observatory does not provide any information about distortions or sulfur dioxide emission anomalies. Some particulate matter emissions are reported on 13, 14 and 15 October at about 600 meters above sea level. active crater.
The last eruption of the complex is dated 2010-2011, following the Maule earthquake (link to the GVP report)

The activity of Nevados de Chillan was marked yesterday November 7 by an explosion and an earthquake associated with 11:24; a plume of ashes rose to 1,500 meters.

At 23:03 local time, a vigorous explosion again occurred, associated with an LP earthquake related to the dynamics of internal fluids; Incandescent blocks were ejected hundreds of meters from the point of emission ... probably a more or less significant destruction of the lava dome

At Veniaminof, the eruption continues with the emission of a westward drifting plume of ash and an outpouring of lava that feeds a 1.1 km long flow, characterized by a high surface temperature. Low amplitude tremors are recorded continuously.

High resolution images of the eruption were acquired by the WorldView-2 satellite on November 5th.
The image is shown in false color (near-infrared, red, and green bands) to highlight the lava channel. The left figure shows the continuous ashy plume that drifted northeast throughout the day on November 5. There is also a fresh tephra deposit on the snow that is likely from the previous day when the plume was heading east. In the close-up of the lava flow on the right, it is possible to see the active lava channel along the western flow margin that is feeding the flow front, where there is a small steam plume. The active flow length along the channel is ~1.1 km and the channel width ranges from 10 meters near the vent to 60 meters distally. The newer flows are snow-free, while the older eastern lobe appears to have a dusting of snow on top. Ice continues to collapse around the flow front from melting.

The images of Satellite Sentinel 2 of 7 november complete this picture of the current eruption; the radiative power is low with 9 MW recorded by Mirova.
