Since the explosive eruption occurred at the volcano on 21 October, a strong constant degassing continues to be active from the summit vent.
Surveillance cameras located on the Sincholagua (northeast) and Rumiñahui (northwest) volcanoes observed gas and steam plumes that have been rising 2 km above the crater.
Although, the activity is still characterized as low-leveled.
Ground deformation data follow the pattern of deflation (subsidence) on the western slopes rather than inflation (uplift), portrayed as blue in the attached InSAR image.
Crater temperatures depict similar values to those after the 2015 eruption. The maximum recorded temperatures reached about 98 °C, however, are underestimated due to an abundant presence of gases and vapor.
Thus, a risk of an impending eruption remains high as a certain rate of uncertainty prevails in monitoring data and volcano behavior so far.
