Tungurahua volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 23 October-29 October 2013 (New Activity / Unrest)
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.
