When it comes to the Poás Volcano in Alajuela, specialists inspected the active crater and confirmed that the lake has disappeared, the crater now shows at least two geological structures called “tuff ring” . The volcano continues to show a column of gases and vapor with aerosols that sometimes show blue and yellowish colors because of the fine particles of sulfur, sulfate, silica, and drops of sulfuric acid that are now exposed to the atmosphere due to the disappearance of the acid lake.
