The National Geology and Mining (Sernageomin) reported Sunday that in recent days there has been an increase in seismic energy volcanic complex Nevados de Chillán, in southern Chile, and opening a crack in the bottom of a new crater.
Faced with this situation, Governor of Dims, Alvaro Miguieles, warned that "we are facing an active volcano and which have been updated evacuation plans against volcanic risk".
Miguieles said that regarding the opening of the crack in the bottom of the fresh crater "Detail of images taken in flyby show that it has a length of 30 to 40 meters".
Experts noted that during the last weeks cameras installed near the volcanic complex showed sporadically filament, occasionally in time and associated with some explosions, which is then observed permanently, probably linked to the opening of the aforementioned crack .
Currently, the system Civil protection maintains exclusion within three kilometers around the active craters and continued restricted access to that area completely, about 400 kilometers south of Santiago, Maintaining a yellow alert.
According to the SERNAGEOMIN, in Chile there are more than two thousand volcanoes, of which 125 are considered geologically active and about 60 have had some kind of historical eruptive activity over the past 450 years.
Chile is the country with the second largest and most active volcanic chain in the world after Indonesia, with the so-called "Ring of Fire".
This chain of volcanoes along the western coast of South America is where the most active volcanoes in the world are.
