Strong strombolian eruption from Fuego last night (image: afartv/x.com)
The volcano showed very dramatic activity yesterday.
A strong eruptive episode (likely to be classified as paroxysm) occurred from the summit crater at about 02:45 AM local time. The lava fountaining episode threw glowing lava bombs and blocks up to several dozen meters; some lava jets might have surpassed 100 meters above the crater.
Incandescent rockfall avalanches were observed descending in all edifice directions. Copious white-to-grey ash emissions accompanied the event.
