LP type of earthquakes associated with fluid movement, maintain low levels, and decreased slightly compared to the previous week. They were observed on the average of 65 LP / day. Similarly, the energy of this type of low seismicity is maintained.
Regarding the activity of hybrid-type earthquakes, linked to the rise of magma, they have increased slightly, showing in this period analyzing two peaks of high seismic activity (30 hybrids in one day). It was, on average, 17 hybrid recorded daily. The hybrid energy values are low
The type of seismicity VT (fracture type earthquakes) again show an increase in the number of earthquakes observed on average with 117 VT / day.The energy values are low and show an average of 1 MJ / day.
During this period (December 29, January 4), and observing the images captured by the camera Campbell Scientific IGP, it has been possible to continue to enjoy the bluish gas emissions (magmatic gases) sporadically, with low density .
The maximum height reached by emissions was 1800 meters above the base of the crater. In this period, there was the expulsion of ash.
Temperature anomalies: The Mirova system (monitoring hot spots on the surface of the crater – www.mirovaweb.it) continues to detect temperature anomalies for the period, with a maximum of 4 MW. Note that, between November and December the number of thermal detections increased, including two 10-megawatt peaks, indicating the presence of a warm body to the surface of the crater.
Anomalies SO2: The satellite system « EOS Aura » GSDM-NASA (monitoring the density of SO2 gas – http://so2.gsfc.nasa.gov/) did not notice any major anomalies in the density values SO2 gas during this period.
