santiaguito

Fresh volcanic ash emissions were observed from the Santa María volcano in Guatemala on January 21, 2025. The ash clouds reached an altitude of approximately 5 km (16 000 feet) above sea level (a.s.l.) and were carried westward at a speed of 18 km/h (11 mph). Residents in the San Marcos Palajunoj and San Martín Sacatepéquez areas may experience light ashfall, with further activity posing risks of long-range pyroclastic flows towards the southwest, south, and southeast.

The Santiaguito volcanic dome complex in southwestern Guatemala is experiencing increased eruptive activity, with frequent explosions and lava block detachment from the Caliente Dome. The eruptions produce ash plumes reaching 3.5 km (11 500 feet) a.s.l. and dispersing it up to 30 km (19 miles) southwest and south.
