Strombolian activity at Tungurahua volcano
On the night of 17 and the morning of November 18 was registered a further increase in the activity of the Tungurahua volcano. This activity was characterized by the emission of water vapor columns with a moderately high load of ash that reached a height of 3km and moved towards the northwest. Within hours of the night, incandescence was observed in the crater with the expulsion of ballistic material reaching a height of 500m and falling to 500 m on the sides without affecting populated areas.
Between 2:10 and 3:30 strombolian activity has become more intense than in the last 24 hours, accompanied by a strong emission of ash. The technicians at the volcano Tungurahua Observatory (OVT) received several reports of ash fall from the volcano surrounding towns such as Pillate, Cotaló, Chontapamba, Chonglontus, Chacauco and Cusúa and in the cantons of Tisaleo, Quero, Cevallos, Mocha and Pelileo, in the province of Tungurahua. Right now a constant steam emission was observed with a moderate load of ash towards the northwest.
