Activity bulletin of volcanic complex Planchon -Peteroa.
The level of activity of the volcanic complex is at the level:
YELLOW: changes in the behavior of the volcanis activity -Time for 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 this period, eleven (11) events related to rigid materials fracturing process (called volcano -tectoniques VT) were recorded, the largest of which had a maximum local magnitude (ML) equal to 1.4 M, located 2.9 km to the northeast (NE) of the main crater at a depth of 6.4 km.
Similarly, they were categorized 4840 events associated with the fluid dynamics inside the volcano, known as long time events (LP), the more energetic with a local magnitude (ML) of M1,1 and a reduced displacement value (DRC) equal to 3,1cm2.
The images from the IP camera, showed no degassing of the main crater.
The images published by the OMI Group (Ozone Monitoring Instrument) Sulfur Dioxide Group (http://so2.gsfc.nasa.gov/) NESDIS (National Environmental Satellite, Data information – http: // satepsanone .nesdis.noaa.gov) reported no abnormality in sulfur dioxide emissions (SO2) into the atmosphere in the volcanic complex sector.
Thermal radiation released by the MODVOLC (Moderate Resolution Imaging Spectroradiometer – http://modis.higp.hawaii.edu/) MODIS, on its website , and Mirova (Middle InfraRed Observation of Volcanic Activity) on its website (http: / /www.mirovaweb.it/), surveillance systems that indicate significant changes in surface temperature, have issued any reports of heat alerts in the zone 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 and a slight decrease of onset, the activity of the volcanic system continues with an activity above the base rate.
For the above the level of volcanic alert level remains at Yellow.
