In Cotopaxi / Ecuador, since Saturday, August 22, emissions of ash is more sustained and height of the plume up to 2,000 m. over the top.

The tremor was recorded continuously since August 22 at 9:41 p.m., with a gradual increase in amplitude; the signal is always present at the last report of the IGEPN (evening of 24.08)

The ash plume takes an O-SO direction, with ash fall on Mulaló, San Ramón and Pastocalle.

According to the IG, compared with previous days, the height of the eruption column and the stray field, are more important, suggesting that we are in the presence of a greater internal pressure, possibly related to the rise of a volume of magma.
