Significant ground deformation triggers Yellow alert at Puyehue-Cordón Caulle volcanic complex, Chile
The Puyehue-Cordón Caulle Volcanic Complex in Chile was placed under a Yellow alert at 20:00 UTC on April 26, 2024. This decision followed observations of increased ground deformation linked to an active inflation zone, located 6 km (3.7 miles) west-northeast of the 2011 eruption site. Monitoring data have shown the highest deformation rates since measurements began, reaching up to 2.4 cm (0.95 inches) per month.
