Fuego Volcano, the most active volcano in Guatemala erupted on 3 June generating a column of ash, lava, and pyroclastic flows up to 10km from the crater. The eruption affected over 1.7 million people in Sacatepéquez, Escuintla, and Chimaltenango departments. On 5 June a new violent descent of pyroclastic lava flow led to new evacuations and casualties. A new lahar (volcanic mudflow) formed on 7 June and is descending through the valleys of Santa Teresa, Mineral, and Taniluya. Some 12,407 people have been evacuated and over 4,000 are living in emergency shelters. Urgent shelter, health, food, and WASH needs have been identified.
