The OVFGO reports a weak fumarolic activity of white color at Fuego on August 31, interspersed with explosions, at a rate of 5 to 8 per hour, weak to moderate; sometimes a louder explosion may occur. They generate plumes of gas and ash at an altitude of 4,500-4,800 m., dispersing over 10-20 km in a westerly and southwesterly direction, and cause avalanches in the contours of the crater, towards the barrancas Ceniza, Santa Teresa, Taniluya and Trinidad, and ashfall southwest of the volcano.

Incandescent pulses are observed during the night and the morning at 100-300 meters above the crater.

A moderate eruptive activity at the Ebeko volcano in the northern Kuriles continues on August 31. According to visual data from Severo-Kurilsk volcanologists, an explosion sent ash up to 2.5 km a.s.l., an ash cloud drifted northeast from the volcano.

Moderate eruptive activity of the volcano continues. Ash explosions up to 6 km (19,700 ft) above sea level could occur at any time. Ongoing activity could affect low-flying aircraft and Severo-Kurilsk airport.

The aviation color code is orange.

 

Code orange still prevails for Sheveluch, Karymsky and Chikurachki volcanoes. The Bezymianny is in code yellow.

Popocatépetl - 30.08.2022 / 06:53 - webcamdeMexico / Cenapred

Popocatépetl - 30.08.2022 / 06:53 - webcamdeMexico / Cenapred

At Popocatépetl, 502 minutes of tremor were recorded on August 30; the same day  at 01:17 local time, a moderate explosion was detected.

During the last 24 hours, thanks to the monitoring systems of the Popocatépetl volcano, 75 low intensity exhalations have been detected, accompanied by water vapor, volcanic gases and sometimes slight amounts of ash.

At the end of the morning, a constant emission of water vapor and gas is observed, dispersing in a West North-West direction.

CENAPRED urges NOT TO APPROACH the volcano and especially the crater, because of the danger of falling ballistic fragments (image 4) and, in case of heavy rains, to stay away from the bottom of the ravines because of the danger of mudslides and rubbish.

The Popocatépetl volcanic alert traffic light is in YELLOW PHASE 2.

Sabancaya - activity bulletin from 22 to 28.08.2022 - Doc. I.G.P.

Sabancaya - activity bulletin from 22 to 28.08.2022 - Doc. I.G.P.

The I.G.Peru informs us of a moderate eruptive activity during the week of August 22 to 28, 2022 at Sabancaya, with the occurrence of an average of 48 daily explosions, which are accompanied by plumes of gas and ash reaching up to at 2,500m. above the top.

During this week, the seismicity was marked by 340 earthquakes of volcanic origin, associated with the circulation of internal magmatic fluids and by VT earthquakes, in connection with the fracturing of rocks.

No significant deformation anomalies. Fifteen thermal anomalies, max. 25 MW, have been identified, associated with the presence of a dome in the crater.

 

The volcanic alert remains in Naranja, with a non-accessible zone of 12 km radius around the crater.
