"On 19 May seismicity at Fuego increased and explosions were heard at 5-10 minute intervals. A 600-m-long lava flow descended the W flank, and a 1-km-long and 20-m-wide lava flow descended the E flank, reaching the base of the volcano. Explosions ejected incandescent tephra 400 m above the crater, and produced ash plumes that rose 5 km above the crater and drifted 30 km S and SW. Coordinadora Nacional para la Reducción de Desastres (CONRED) raised the Alert Level to Orange (the second highest level on a 4-color scale). Pyroclastic flows also descended the flanks, prompting authorities to restrict passage on part of a highway. Ash plumes from the pyroclastic flows rose 3 km above the crater. Ashfall was reported in Morelia (7 km SW), Panimaché I and II (9 km SW), Sangre de Cristo (8 km WSW), and Yepocapa (8 km WNW). Thirteen people from El Porvenir in Alotenango (8 km ENE) evacuated to local shelters. Visual observations and seismicity indicated that activity decreased later that day.
On 20 May a few explosions generated ash plumes that rose 500 m above the crater and drifted 8 km SW. The next day cloud cover prevented observations; however explosions, rumbling, and degassing sounds were reported. On 22 May explosions generated ash plumes that rose as high as 1 km and drifted 10 km S and SE. Rumbling was heard and shock waves were detected. The lava flows were inactive and only incandescence from block avalanches was observed." [less]

The eruption was both explosive and effusive. According to news, the eruption began at 2:45 a.m. with large explosions and lava fountains possibly up to 1 km high from the summit crater. Large incandescent bombs were ejected to considerable distances and showered the summit cone of the volcano. A 500 m long lava flow traveled down on the SW flank towards the Ceniza ravine. The eruption also produced an ash column reaching 5 km (16,000 ft altitude) and pyroclastic flows probably generated mostly by cascading lava blocks traveling down the steep cone's flank into Las Lajas, El Jute y Ceniza valleys.
Ash fall was reported from nearby villages mainly to the S and SW including Morelia, Panimaché I and II, Sangre Cristo and Yepocapa. [less]

Several block lava flows are traveling down from the dome, and generate glowing avalanches. Frequent explosions produce ash plumes rising 800-900 m above the lava dome. An explosion on 26 March produced pyroclastic flow on the western flank of the cone.
Satellite images detected several plumes extending up to 33 km in south-westerly directions. Ash fall occurred in up to about 10 km distances in areas to the south at the Observatory Vulcanológico de Santiaguito (OVSAN), and to the SW at the El Faro, La Florida, and Patzulin ranches (SW), as well as in the village of Santa María de Jesús (SE).

The lava flow in the direction of Taniluyá is between 150-200 m long, and incandescent blocks detach from the front, tumbling down into the forested area. [less]

Weitere Entwicklung von der neuen Lavastrom auf der südwestlichen Flanke in Richtung der Schlucht Taniluya erreichen knapp über 200 Meter lang, Wunderkind Blöcke ankommen und Vegetation zu beobachten. [less]

Fels Lawinen reiste SW in die Ceniza Entwässerung und auf die W, S und SW Flanken. In der Nacht am 13. und 16. Januar wurde Glut aus dem Krater sichtbar.
