Tungurahua, Ecuador

The IG reported that during 22-23 July, explosions from Tungurahua were detected by the seismic network. An ash plume rose to an altitude of 9 km (29,500 ft) a.s.l. On 25 July, lahars descended two drainages on the W flank. On 26 July, ash-and-steam plumes drifted NW and SW, and explosions and roaring noises were reported. Nighttime incandescence from the crater was noted. On 27 July, roaring noises accompanied ash plumes that rose to altitudes of 8-10 km (26,200-32,800 ft) a.s.l. Ashfall was reported in areas to the SW. During 27-29 July, incandescence was seen around the crater and blocks rolled 800 m down the flanks. Noises were reported and explosions caused windows to vibrate. Ashfall was reported in areas to the SW.
