Authorities of the National Geology and Mining Service (Sernageomin) of Chile They reported this Friday that the Villarrica volcano presented changes that allow the orange alert status to be modified. This way you will now be in “yellow alert.”
The measure was motivated by the information obtained with the monitoring of the information obtained through the monitoring equipment of the National Volcanic Surveillance Network and analyzed at the Southern Andes Volcanological Observatory (OVDAS).
“During the last few days the instrumental parameters of the Villarrica volcano have shown a gradual return towards moderate levels of activity,” reads the statement from the Chilean national authority.
Regarding the seismicity values in the Villarrica volcano, a domain of discrete LP-type signals and some tremor pulses is described. with energy values that have stabilized at values close to 1 um/sec.
«From the above, it is concluded that the anomalous process that began in the last days of September has gradually lost power.«Adds the official information.
He Sernageomin explains that surface phenomena have lost power and recurrence, observing gaseous emissions of low altitude and on certain occasions with low content of pyroclastic material. However, some Strombolian explosions have been recorded that eject material in the area near the crater and generate nocturnal incandescent phenomena.
In this scenario, the possibility of evolution to more energetic phases decreased, they explained. However, “the occurrence of explosive activity that might affect the upper part of the volcanic edifice is not ruled out.” they added. For this reason, the volcano will be monitored under the yellow technical alert criteria in a probable impact area of 2 kilometers from the center of the crater.
