SUMMARY OF THE ACTIVITIES OF THE VOLCANO.
The activity of the volcano is moderate.
Continuous emissions of vapor and ash is recorded, with heights up to 2000 meters, heading North and Northwest . At night , glow was observed in the crater, incandescent blocks are descended until 1,200 meters below the summit. So far it has reports of ash fall to the west of the volcano. It was recorded rainfall which generate lahars on the western flank.

TECHNICAL AND OBSERVATIONS APPENDIX
Seismicity:
From 11:00 (TL) yesterday until 11:00 (TL) today, a continuous tremor emission was maintained (TREM) and 28 explosions (EXP) were recorded.
Observations of emissions and ashes:
Yesterday morning were heard rumblings intense, emissions have continued, ejecting clouds of gray ash up to 1,000 meters above the crater in Northwest direction. Pyroclastic flows that go down into the Quebrada Romero sector to 1000 meters below the crater and in the Quebrada Achupashal sector up to 500 meters below the crater were recorded. In the afternoon, the roars were more intense than in the morning, and emissions were heading north at a height of 2000 meters above the crater.

During the night, the rumbling were intensified and it was observed glow in the crater. Emissions of incandescents blocks were noted up to 1200 meters below the crater, on all sides. The day was cloudy,and , in the clouds, a steam emission with a moderate load ashes to the North-West that reached 800 meters above the peak was observed.
there was ash falls reports in areas of Jewish, Quero, Cusúa Chacauco.
Rain and lahars:
Some rain in the morning that generated mudflows (lahars) in the ravines of Achupashal, Jewish, Pondoa, Mandur, Pingullo, Rea Chontapamba were recorded.
Note that the mudslide that descended through the ravines of Pingullo Cusúa led to the closure of the road.

GENERAL INFORMATIONS
If the rains are more intense in the volcano area, they can re-mobilize deposits from pyroclastic flows and generate lahars . For this reason, we recommend extreme caution when driving on roads and highways that pass through the gorges or these flows went down and in the regions which in the past have been affected by this kind of phenomenon.

News of Sunday, March 6:

Seismicity:
From 11:00 (TL) yesterday until 11:00 (LT) Today, there remains a continuous emission tremor (TREM) and it was recorded 29 explosions (EXP).
Observations of emissions and ashes:
Yesterday afternoon, continuous vapor emissions were observed with a moderate load of ash that reached an altitude of 2500 m, in a westerly direction. These events were also accompanied by rumbling.
During the night, the volcano was completely clear, and it could be observed glow in the crater , incandescent blocks rolling down his sides up to 2000 meters below the crater.At dawn and this morning, the volcano was clear, and at 09:30 (TL), explosions were recorded, which generated the vibration of the ground and windows in areas near the volcano. These events were also accompanied by pyroclastic flows that came down to about 1000m below the level of the crater in the gullies of Achupashal, Rea, Pondoa, Mandur.

At the end of this newsletter the volcano’s crater level is again covered.
So far there are reports of many gray ash fall in areas of Pillate, Bilbao, Choglontús, Pelileo.
