The eruption continued at Fuego / Guatemala 24 hours after its start.

Incandescent projections are observed at 500 meters above the crater, and form a column of ash 4,500 m. asl, traveling over 20 km to the southwest and west.

Explosions feed lava flows in the ravines El Jute and Las Lajas, long of 2,000 meters, and avalanches of blocks in the barranca Tanilyua. Ash falls are continuing on San Pedro Yepocapa, Sangre de Christo, Morelia, Santa Sofia Panimache among others.
