Santiago de Chile, October 31 (Prensa Latina) The Chilean authorities keep the red alert in the south of the country due to the Hudson volcano’s eruptive activity and also from the volcanic complex of Puyehue Cordon Caulle.

Although the Hudson, located in Aysen region, registers a minor eruption and the external signs tend to fall, there is no magma movement inside the massif, of a 1, 960 meters high and located about two thousand kilometers far from this capital.

The director of the National Geology and Mining Service, Enrique Valdivieso, said that monitoring equipment installed, permit the control of what happens in and out of the volcano. We know how it is behaving, “he said.

Yesterday Pilar Cuevas, mayor from Aysen said Monday they will decide whether or not the cessation of red alert for Hudson, whose last major eruption took place between Aug 8 and Dec 29, 1991.

The same applies to the Puyehue-Cordon Caulle with a flow volume of ash emission since last June and is checked by air navigation in cities of Argentina and Chile, relieved by periods depending on the direction of the wind.

The main problem for the aircraft is not only visibility due to the ash presence in the air, but also the abrasive effect it has on the fuselage of the aircraft and engine overheating them that may come to a halt in midair.
