Ticsani , Peru : 192 earthquakes related to fracturing of rocks were located,

Surveillance volcano tectonic:
The volcano-tectonic earthquakes (VT), related to the breaking of rocks, near the Ticsani (less than 6 km from the crater) continue to observe a decline, having in the last two weeks of June an average of 42 VT / day (report No. 06-2016; 45 VT / day).
The occurrence of volcano-tectonic earthquakes Distals (EDV) have an average rate of 51 EDV / day, lower than the previous period (Report No. 06-2016; 343 VT / day). This type of seismic activity may be related to local tectonics.
On the other hand, there have been five hybrid-type earthquakes, low energy (less than 0.5 MJ), this seismicity is associated with an inside magma movement of a magma chamber.

Location of event:
During this period, a total of 192 earthquakes related to fracturing of rocks were located, reaching a maximum of 3.8 ML (local magnitude). The epicentral distribution and depth of earthquakes shows two groups: the first group is close to the volcano (VTS near the dome) and extends to the east, at depths of between 4 km and 7 km beneath the Ticsani. The second group is at a distance of 11 km to the southeast of the volcano (VTDs) distributed between 3 km and 12 km deep under the surface.
The largest magnitude event, 3.8 ML, was recorded on June 25 at 9:26 HL (local time). This earthquake was located 12 km southeast of the volcano Ticsani in the second group described above.

Satellite Surveillance:
SO2 anomalies: The satellite system “EOS Aura” GSDM-NASA (http://so2.gsfc.nasa.gov/) recorded low gas density values of SO2 in the period.
Thermal anomalies: The Mirova system (of www.mirovaweb.it) not detected thermal anomalies on the Ticsani volcano (VPR = 0 Mega Watts).
