Tungurahua, Ecuador

The IG reported that although visual observations were mostly limited due to cloud cover during 16-22 April, ash-and-steam plumes from Tungurahua were spotted on 16, 20, and 21 April and rose to altitudes of 6-8 km (19,700-26,200 ft) a.s.l. Strombolian activity at the crater was noted at night on 15 and 20 April. During 16-19 April, explosions were registered by the seismic network. Ash plumes drifted W and SW; ashfall was reported in areas downwind during 19, 20, and 21 April. On 21 April a lahar disrupted the Ambato-Baños route for a few hours.
