Sabancaya - activity summary between 2 and 8 March 2020 - Doc. I.G.Peru

The Peruvian Geophysical Institute (IGP) reports that the eruptive activity of the Sabancaya volcano between March 2 and 8 remained at moderate levels, with the continuous recording of moderate explosions and the consequent emission of ash and gas. Consequently, for the following days, no significant change is expected regarding its activity.

During the above-mentioned period, the IGP recorded and analyzed the occurrence of approximately 748 earthquakes of volcanic origin, associated with the circulation of fluids (magma, gas, etc.) inside the volcano, in addition to 17 daily explosions of medium to low intensity, accompanied by columns of gas and ash up to 3.7 km high above the summit of the volcano, scattered towards the west, north and northwest sectors of the volcano.

The monitoring of the deformation of the volcanic structure records significant anomalies. Satellite surveillance has identified the presence of 5 thermal anomalies with values ​​between 1MW-15MW, associated with the presence of a lava body in the crater.

It is recommended to maintain the level of volcanic alert in Naranja and not to approach a radius of less than 12 km from the crater.

Ubinas - activity summary between 2 and 8 March 2020 - Doc. I.G.Peru

Ubinas - activity summary between 2 and 8 March 2020 - Doc. I.G.Peru

The Geophysical Institute of Peru (IGP) reports that the eruptive activity of the Ubinas volcano, between March 2 and 8, remained at low levels. To date, the record of earthquakes that would be associated with the rise of magma to the surface is weak. In addition, there are sporadic emissions of bluish gases (of magmatic origin) and water vapor. According to this scenario, the possibility of volcanic explosions and / or low ash emissions remains low. The volcanic alert could be lowered to Amarillo.

Cenapred reports for the last 24 hours to Popocatépetl, 176 exhalations accompanied by water vapor, volcanic gases and slight amounts of ash, and two minor explosions, one yesterday at 5:28 pm and the other today today at 07:46 h.

797 minutes of small amplitude tremor were also counted. During this morning, a slight fall of ash occurred in Amecameca, in the State of Mexico.

Then, volcanic gas emissions and small amounts of ash dispersed in the northeast of the north.

Popocatépetl volcanic alert remains at Amarillo Fase 2

In Ecuador, the IGEPN reports a high and unchanging explosive activity at the Sangay and Reventador volcanoes, with emission of ash and gas plumes respectively at 6,400 meters and 4,600 meters above sea level, according to VAAC Washington.

Alert levels remain unchanged
