IG reported that activity at Tungurahua remained at moderate levels during 6-12 November. Although cloud cover sometimes prevented visual observations of the crater, ash plumes were observed on most days. An ash plume rose 1 km and drifted W on 7 November.
The next day ashfall was reported in Runtún (6 km NNE), Pondoa (8 km N), and Baños (8 km N). On 9 November an ash plume rose 3 km and drifted W, and blocks rolled down the flanks. Ash fell in Choglontus (SW), Bilbao (W), and Cusúa (8 km NW).
On 10 and 12 November ash plumes rose 1 km and drifted SW, and 1.5 km and drifted W, respectively. Ashfall was reported in El Manzano (8 km SW) on 12 November.
