Since July 28, the activity of Tungurahua is rising. On 29.08, the volcano emitted steadily  water vapor from the crater.
On 1 August, from 10 h30, three small plumes rising, moderately loaded in ash, two kilometers high ... followed at 14:50 local, by a significant release of ash, formed a plume 4,000 meters before heading to ONO.
SO2 emissions are rising, with 30 and 31 July  respectively 2966 tonnes / day and 1963 t / d , in relation to the presence of fresh magma in the upper volcano conduits.

The level of seismicity is up too, with tremor for two days and on 1 August, a volcano-tectonic earthquake of magnitude1, 9 to a depth of 5 km. ,presumably related to fracturation of rock.


The OVT indicates a high probability of a large explosion in the short term, probably accompanied by pyroclastic flows in drainage, up to inhabited areas and significant ash falls.
