Among the various techniques used in the paper are the use of satellite images (provided by IRD in France), infrared spectral bands to determine temperature, morphological analysis and geological evidence.

Using satellite imagery and other analysis methodologies, The National Geological and Mining Service, Through the National Volcanic Surveillance Network (RNVV), it was established that on October 20, a mass elimination event took place inside the Bernardo O'Higgins National Park in the sector Areas of the South Ice.

National Director Alfonso Domeyko said that "as Sernageomin we have done the appropriate analyzes to determine in detail the causes of this avalanche of rocks and, in turn, we have provided the background to Onemi's civil protection system members to make the appropriate coordination He added that "a field visit is being evaluated to get more precise information about it".

RNVV chief Álvaro Amigo, on the other hand, explained that, according to his first records, this is associated with a mass move that has an extension of three kilometers, which did not affect the coverage of the nearby glacier. In this way it would be excluded that it is a lava flow or associated with volcanic ash emission.

Regarding the origin of the event, Amigo said that it is not possible to establish with certainty until now, but the more likely hypothesis would correspond to a mass elimination triggered by the instability of hills in the mountainous area.

Among the various techniques used in the paper are the use of satellite images (provided by IRD in France), infrared spectral bands to determine temperature, morphological analysis and geological evidence.

Sernageomin keeps track of 45 active volcanoes in the country and has initiated some negotiations to extend the surveillance network in the Magallanes and Chilean Antarctic regions.
