The activity level of the volcanic complex is at: YELLOW, changes in the behavior of volcanic activity.
probable time for an eruption weeks / months.
Based on the analysis of information obtained from monitoring equipment and surveillance of the volcanic complex, the National Service of Geology and Mining (SERNAGEOMIN) through the Volcanological Observatory of Southern Andes (OVDAS) communicates :
During this period, fifteen (15) events in connection with rigid materials fracturing processes (called volcano – tectonic, VT), with the largest local magnitude (ML) of M 1.1 . , Located 1.1 km to the south-southeast (SSE) of the main crater were recorded.
Similarly 4787 earthquakes associated with fluid dynamics inside the volcano (called long period, LP), with a local magnitude (ML) of less than M 1.1 and are reduced displacement values (DRC ) less than 4.4cm2 were classified.
The images from the IP camera show no clear evidence of surface activity.
Images published by the Group Sulphur dioxide ((instrument to monitor ozone – http://so2.gsfc.nasa.gov/) and NESDIS (National Environmental Satellite, Data, and Information, IMO group – Http: // satepsanone.nesdis.noaa.gov) reported no abnormality of sulfur dioxide (SO2) into the atmosphere in the volcanic complex area .
Thermal radiation released by the MODVOLC (Moderate Resolution Imaging Spectroradiometer) MODIS on its website (http://modis.higp.hawaii.edu/) and Mirova (Middle InfraRed Observation of Volcanic Activity) on its website (http: / /www.mirovaweb.it/) monitoring indicates significant changes in surface temperature, reported no heat alert in the area associated with the volcanic complex.
There are no reports of local authorities or communities about anomalies seen in the volcanic area.
Although the recorded events have low energy levels, the high rate of daily appearance of this type of seismicity which is maintained since the beginning of February continues, suggesting an excitation of the volcanic system above the level reference.
In this scenario, there is a possibility of occurrence of small ash emissions. Therefore, the volcanic alert level remains at Yellow.
