The National Geology and Mining Service (SERNAGEOMIN) – Volcano Observatory of the Southern Andes (OVDAS) announces that Friday, January 29, 2016 at 14:25 local time (5:25 p.m. GMT), occurred a new emission of ash from the Nevados de Chillan volcanic complex , associated with the recording of a seismic tremor signal , with a reduced displacement of 5.6cm2. The particularity of this activity is that the focus of the emission of volcanic material is located in the crater Arrau, in addition to the continuation of emissions in the newly formed crater.
This suggests a change in the activity of the hydrothermal system, influenced by heat transfer from a magmatic body underlying involving destabilization of the greater part of the hydrothermal system, raising the possibility of generating greater phreatic explosions and / or phreatomagmatic eruptions.
The level of technical volcanic alert level remains at yellow, with particular attention to its evolution.
SERNAGEOMIN -OVDAS continuous online monitoring, and report timely to the changes in volcanic activity in the region.
