Fuego volcano (South-Central Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 15 March-21 March 2023 (Continuing Activity)
Thu, 16 Mar 2023, 11:00 11:00 AM | BY: VNINSIVUMEH reported that 4-10 explosions per hour were recorded at Fuego during 15-21 March, ejecting incandescent material up to 400 m above the crater and generating ash plumes that rose as high as 1.3 km above the crater rim. The ash plumes drifted as far as 20 km in multiple directions. Ashfall was reported on a few of the days in areas downwind including, Morelia (9 km SW), Panimaché I and II (8 km SW), Santa Sofía (12 km SW), El Porvenir (8 km ENE), Finca Palo Verde, La Rochela, Finca Asunción, Ceilán, San Andrés Osuna, Aldeas, and San Pedro Yepocapa (8 km NW).
Daily block avalanches descended the flanks in various directions towards the Ceniza (SSW), Santa Teresa, Seca (W), Taniluya (SW), Trinidad (S), Las Lajas (SE), Honda (E), and El Jute (ESE) ravines, sometimes reaching vegetated areas. Shockwaves caused structures to shake in communities immediately surrounding the volcano. A lahar notice issued at 1530 on 15 March described lahars in the Ceniza ravine that carried branches, tree trunks, and blocks 30 cm to 1.5 m in diameter.
Lahars on 18 March descended the El Jute and Las Lahas drainages, carrying branches, tree trunks, and blocks 30 cm to 1.5 m in diameter.
