There are known 39 pronounced eruptions since 1828.
The volcano’s main crater contains one of the most acidic lakes in the world!
Laguna Caliente
Laguna Caliente often has a PH of 0! The bottom of this lake contains liquid sulfur.
The diversity of colors of the lake is fascinating. It might be emerald green then hours later grey-whitish. Sometimes rafts of brilliant, yellow sulfur are seen floating in the lake.
