The volcano continues to emit a near constant steam and ash plume rising on average 1.5 km with peaks of up to 4 km above the crater. This activity produces significant ash fall in areas west of the volcano such as Sabañag, Santuario, Hualcanga Santa Anita, Jaloa la Playa, Pillate, Hierbabuena, San Juan and other rural areas of Quero, Cevallos, Tisaleo and Mocha.
Individual explosions observed during the night 19-20 Aug eject large incandescent bombs to heights of up to 500 m and to a radial distance of 1.5 km from the rim, mostly towards the NW and W.
Constant turbine and rumbling noises accompany the activity and are heard around the volcano and as far as the towns of Ambato and Riobamba.
A a slight decrease of the tremor signal was noted by IG yesterday. SO2 satellite images show a strong plume drifting west from the volcano.

The eruption continues with constant steam and ash emissions generating a plume 1.5 km above the crater, intermittent cannon-shot-like explosions of moderate strength, which eject blocks of considerable size, and pyroclastic flows reaching 1.5 km distance. During 19 Aug, 4 pyroclastic flows were counted that went towards the areas of Cusúa and La Pirámide. ... [more]
