IG reported that after a 3-month lull in activity at Tungurahua, a new eruption that began on 6 October was characterized by increased seismicity, Strombolian activity that ejected incandescent blocks, and ash plumes that produced ashfall in nearby areas. Seismicity peaked on 11 October and high-level ash plumes again produced ashfall in nearby towns. The number of explosions increased on 14 October and two small pyroclastic flows traveled a few hundred meters the next day.
