At the moment, this is Ecuador's most active volcano. According to the Istituto Geofisico (IGEPN), its activity is "high". A lava dome continues to grow at the summit crater.

Strong degassing generates a plume of steam and gas rising 500-1000 m and frequent small to moderate explosions produce ash plumes that rise to similar heights. In total, IGPEN counted 38 explosions during an 24 hour interval, based on seismic and webcam observations. Most of the time, these can not be observed directly due to frequent cloud cover.
Based on satellite observations, a stronger ash emission was reported by VAAC Washington this afternoon (at 14:18 UTC) with an ash plume reaching 19,000 ft (6.5 km) altitude, or approx. 2 km height above the crater.
