The LP type of seismicity (associated with the passage of fluids) in the analysis of this week presented an average rate of 17 LP / day. In addition, the LP seismic energy remains at low levels.
The number of hybrid-type events (associated with the rise of magma material) shows low values, and recording a HIB / day in the period. In addition, the hybrid energy show low levels.
Seismic Events VTPS or “proximal volcano-tectonic” (very close to the volcano, less than 6 km), showed significant values ??in both size and number. During this period, it was recorded 11 VTPS / day. In addition, the maximum magnitude earthquake generated by a VTP was 2.9 M (local magnitude).
Type of tremor events have decreased slightly to 12 November, with 9 episodes Tremor recorded daily. Their number and energy have declined steadily during this period.
The fumerolics emissions of Sabancaya continue to occur continuously, 24 hours a day, with medium to high densities during this period.
Their coloring is mainly, as in recent months, whitish (water vapor). Because of the abundant clouds in the region over the past week, it was not easy to distinguish the expulsion of bluish gas (magmatic gases).
Between November 10 and 16, the height of emissions did not show great variations. These were maintained between 200 and 900 meters above the crater, approximately.
