Las Derrumbadas
Las Derrumbadas is a rhyolitic twin dome volcano in the Mexican state of Puebla. Often overlooked for its proximity to some of the country's most famous mountains —including Cofre de Perote, Sierra Negra and colossal Pico de Orizaba— its two summits are nevertheless within the top 30 of the country's highest mountain peaks.
Officially, both mountains are individually called Cerro Derrumbadas. To distinguish them, they are called Derrumbada Roja or Derrumbada de Fuego, and Derrumbada Azul or Derrumbada de Agua by the locals. A third mountain, nearby Cerro Pinto, is often included in the Derrumbadas complex, under the name of Derrumbada Blanca.
Due to the volcano's fumarolic activity, it has been studied and proposed as a source of geothermal energy.
