The Turrialba presented yesterday a plume of gases, steam and ashless aerosols, associated with a low to moderate tremor.
Seismicity is characterized by spasmodic and harmonic tremor and LP earthquakes.
In the evening, the plume reflects an incandescence in the crater. During a visit on March 27, the Ovsicori teams recorded a temperature of more than 780 ° C, and an incandescence visible by day at the bottom of the crater.

The explosions at Fuego, numbering 7 to 13 per hour, became more energetic on 31 March. They were accompanied by plumes rising to 4.300-4.600 meters asl, moving to the west over 10 km. Incandescent ejections are observed at 100-330 meters above the crater; they generate moderate avalanches in the vicinity of the crater.
Ash falls and shock waves are reported more than 15 km from the volcano.
