Planchon-Peteroa volcanic complex (February 16 to 29).
The level of activity of the volcanic complex is at:
YELLOW level: changes in the behavior of volcanic activity -Time For a probable 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) announces:
During the reporting period, thirteen (13) events related to rock fracturing process (called volcano-tectonic, VT) with a maximum local magnitude of M 1.1 were recorded. Similarly, it was ranked seven thousand three hundred and one (7301) earthquakes associated with fluid dynamics inside the volcano (called long-period events LP), with local magnitudes (ML) to lower values M 0.7 and a reduced displacement (DRC) below 1,7cm2.
The images from the IP camera showed a small white degassing of the main crater, first suggesting the presence of water vapor. These discharges have reached a maximum altitude of about 400m above the crater.
The images published by the Sulfur Dioxide Group (ozone monitoring instrument: http://so2.gsfc.nasa.gov/) and NESDIS (National Environmental Satellite, Data and Information: IMO Group http: // satepsanone. nesdis.noaa.gov) reported no abnormal emissions of sulfur dioxide (SO2) into the atmosphere in the area of the volcanic complex.
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/), surveillance systems that indicate 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 community, about perception of anomalies in the volcanic area.
Although the recorded events have low energy levels, the gradual increase in the occurrence of events associated with fluid activity indicates that the system appears above the volcanic activity base level, without still unbalanced.
In this scenario, there is a possibility of occurrence of small ash emissions. Therefore the level of volcanic alert level remains at Yellow.
