In the case of Poás Volcano in Alajuela, experts examined the active crater and noticed that the lake has vanished, the crater currently shows two geological structures which are a broad flat crater formed by a phreatomagmatic eruption.
The volcano endures showing a column of gases and vapor with aerosols that show blue and yellowish colors due to the fine particles of sulfur, sulfate, silica, and drops of acid that are clear to the atmosphere due to the evaporation of the acid lake.
