The type of seismicity LP (long period) associated with a fluid movement, continues to occur at low levels of seismicity. In the previous report (Report Nº10-2016 ) it was registered on average 167 LP / day and in this period it shows a slight decrease to 112 LP / day.
The events of hybrid activity associated with magma elevation in this period have shown a low level, both in number and in power, recording an average of only 5 hybrid / day.
The events that determine the rupture of rigid materials (VT) during this period increased slightly, from 93 VT / day (Report Nº10-2016) to 103 VT / day on average. Furthermore, on 12 March, a peak at 188 events were recorded.
Thermal anomalies: The Mirova system (monitoring of hot spots on the surface of the crater – www.mirovaweb.it) detected no thermal anomaly.
SO2 anomalies: The satellite system (monitoring gas density http://so2.gsfc.nasa.gov/ SO 2) “EOS Aura” GSDM-NASA did not detect any major anomalies in density values of SO2 gas during this period.
During this period of analysis (8 to 14 March), he was distinguished sporadic emissions of water vapor in the Ubinas volcano, which reached an altitude of 200 meters above the base of the crater.
The clouds in the area over the previous weeks, remained, which prevented a complete picture of the volcano. There was no explosion and / or exhalation of ash.
On 10/02/2016, the staff of the Municipality of Ubinas mounted at the top reported the presence of a lake in the crater floor. It is very likely that its formation is the result of melting ice and precipitation that occurred in the volcano area. Subsequently, the staff of the OVS corroborated this information.
