Fuego volcano (Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 26 August-1 September 2020 (Continuing Activity)

INSIVUMEH reported that there were 3-16 explosions per hour at Fuego recorded during 26 August-1 September, generating ash plumes as high as 1.1 km above the crater rim that generally drifted 10-20 km NW, W, and SW. Shock waves rattled buildings within a 20-km radius. Incandescent material was ejected 100-300 m high, causing avalanches of blocks in the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), Las Lajas, and Honda drainages; avalanches sometimes reached vegetated areas.
Ashfall was reported in several areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Finca Palo Verde, Santa Sofía (12 km SW), San Pedro Yepocapa (8 km NW), and Sangre de Cristo (8 km WSW). During 26-27 August a lava flow traveled 150 m down the Ceniza drainage and lengthened to 400 m on 28 August; the front of the lava flow generated block avalanches. By 30 August the continuously active flow was 500 m long.
During 31 August-1 September the first 200 m of the lava flow was active and continued to produce block avalanches.
