Tungurahua, Ecuador

The IG reported that on 19 August fumarolic plumes from Tungurahua rose 20 m above the NE crater and on 20 August, steam-and-ash plumes rose about 50 m above the crater. On 21 August, intense rains prompted the Tungurahua Observatory (OVT) to issue a warning of potential lahars in the Vascún river. A natural dam in the river was previously identified as potentially hazardous. On 23 August, a person in El Salado detected vibrations. The dam ruptured and material descended the Vascún river to the N at speeds of 10-15 m/s, destroying a house, damaging and demolishing bridges, and destroying multiple public swimming pools in the Baños area. Two people were injured and two people were missing.
