Activity at Fuego during December 2021-March 2022 included multiple explosions every hour that produced ash emissions that rose as high as 5.2 km altitude and drifted generally W and SW as far as 50 km from the volcano. Sentinel-2 infrared satellite data showed thermal anomalies inside the summit crater, as well as the incandescent block avalanches descending primarily the S and SW flanks five to six times each month (figure 159). A total of 90 MODVOLC thermal alerts were issued. The MIROVA graph showed that frequent and moderate thermal activity was consistent throughout the reporting period, with a pulse in activity during February-March (figure 158). Active lava flows were reported in the Ceniza each month and Ceniza and Santa Teresa drainages during March. Ashfall was frequently reported in nearby communities (table 25). Nighttime incandescence and ejecta could often be seen rising 50-400 m above the summit. The Ceniza and Trinidad drainages were primarily affected by strong block avalanches throughout the reporting period, though all drainages were affected, including Las Lajas, El Jute, Santa Teresa, Taniluyá, Honda, and Seca. The explosions also produced incandescent block avalanches that descended several flank drainages (barrancas), with some of the blocks reaching the edge of vegetation near the bottom. Ash plumes rose to 4.2-5.2 km altitude each day and drifted in different directions, though dominantly W and SW. The frequent explosions that occurred during December 2021 through March 2022 generated shock waves and vibrations that rattled roofs and windows in communities near the volcano. ![]() This report covers similar activity during December 2021 through March 2022 based on daily reports from the Instituto Nacional de Sismologia, Vulcanología, Meteorología e Hidrologia (INSIVUMEH) and various satellite data. Frequent explosions with ash emissions, block avalanches, and lava flows have persisted since 2018. Eruption activity has included major ashfalls, pyroclastic flows, lava flows, and lahars. Most Recent Bulletin Report: May 2022 (BGVN 47:05) Cite this Reportįrequent explosions with ash plumes, and occasional lava flows, during December 2021-March 2022įuego has been vigorously erupting since January 2002 with recorded eruptions dating back to 1531. Source: Instituto Nacional de Sismologia, Vulcanologia, Meteorologia, e Hidrologia (INSIVUMEH) Explosions ejected incandescent material as high as 200 m above the summit on some of the days. Daily block avalanches descended the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), Honda, Las Lajas (SE), and El Jute (ESE) drainages, often reaching vegetated areas. Daily shock waves rattled structures in communities around the volcano. The ash plumes drifted as far as 15 km NW, W, SW, and SSW, causing almost daily ashfall 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), Los Yucales (12 km SW), Sangre de Cristo (8 km WSW), El Porvenir (8 km ENE), San Pedro Yepocapa (8 km NW), La Rochela, San Andrés Osuna, Finca la Asunción, and Ceilán. INSIVUMEH reported that 4-10 explosions per hour were recorded at Fuego during 1-8 November, generating daily ash plumes that rose as high as 1.1 km above the crater rim.
