Sangay volcano (Ecuador): eruption ended after 4 months of continuous activity

A few days ago, the Geophysical Institute of Ecuador (IGEPN) declared that the latest eruption, or eruptive phase, of the volcano can now be considered to have ended.
It had begun on 8 Aug 2018 and lasted approx. 4 months. Seismic and visual eruptive activity sharply decreased since the beginning of December and ceased about 2 weeks ago.

adapted from the original report:
During the 4 months of continuous activity, the main phenomena associated with this period were: the emission of lava flows on the ESE flank and ash columns that were directed mainly towards the west. These volcanic phenomena did not affect significantly any populated areas (which are very sparse in the vicinity of the volcano). Only very light ash fall occurred in the city of Guayaquil on 18 Sep and caused no damage.

Visual Observations and Surface Activity:
Ash plumes
The most significant surface activity during this period were ash emissions reaching typically 900 +- 450 m above the crater and only occasionally exceeded 2 km. On most days the ash plumes drifted toward the west and northwest. During this period the Washington VAAC reported 164 ash alerts

Lava flows and pyroclastic flows
Additionally, there was continuous emission of lava flows from a lateral vent on the upper ESE flank of the volcano. The lava flows descended to 1-2 km downhill, generating glowing avalanches and small pyroclastic flows caused by collapsing lava material on the steep flank. The pyroclastic flows reached distances of up to 7 km from the crater.
