Dense ash emissions from Cotopaxi volcano on 30 May (image: IGEPN)
The explosive eruption at the volcano continues at moderate levels.
It is characterized by near-constant vulcanian-type explosions releasing mostly dense grey ash columns to estimated 21,000 ft (6,400 m) altitude that drifted west and southwest.
The seismic instrument continues to register long-period earthquakes and tremors associated with gas, water vapor and ash emissions.
The MOUNTS system registered a flux of sulfur dioxide (SO2) emissions to be measured at 392 tonnes on 29 May.
