Current seismic recording from Tungurahua (RETU station, IGPEN)
During early October, strombolian activity had increased and explosions have become more frequent (60-100 per day) and ash-rich, sometimes accompanied by loud shock waves. Between 20 and 23 October, activity started to decrease to 20-35 explosions per day with steam and ash columns 2-3 km high, drifting mainly to westerly directions and causing fine ash fall in Palitagua, Chogluntús, El Manzano, Penipe, and Riobamba .
Deflation was recorded in late October, interpreted as the result of degassing and depressurization caused by the numerous explosions. IGPEN is not certain whether the decrease in activity during late Oct is a signal that the eruptive phase is ending or whether it will increase again in the near future.

IG reported that, during the last week of October and the first days of November, moderate activity continued at Tungurahua; there were ~10 explosive emissions recorded. Plumes reached 800-2,000 m above the crater and drifted E and SE; ashfall was not reported from nearby communities. Seismicity included explosions, long-period earthquakes, volcano-tectonic earthquakes, and tremor (often associated with emissions). ... Read all

IG reported that activity at Tungurahua remained high during 23-27 October. Although cloud cover sometimes prevented visual observations of the crater, ash plumes were observed almost daily. During 23-24 October continuous ash emissions produced plumes that rose 3-4 km above the crater and drifted NNE and SW. ... Read all
