COSTA RICA NEWS — A cold front that moved in on Sunday has intensified acid rain in the area of the Turrialba volcano, affecting the communities of Alvarado, Oreamuno and the highlands of Cartago, said this morning the president of the Comisión Nacional de Emergencias (CNE), Iván Brenes.

The corrosive rain occurs when sulfur dioxide expelled by volcano, mixes with rain clouds and falls to the ground.

Brenes, speaking on live radio, explained that acid rain and ash can cause respiratory irritation, so he recommended covering the mouth and nose, as well as avoid skin exposure when outdoors.

The acid rain will also affect electrical equipment and installations.

Brenes also recommends keeping pets and farm animals indoors.

According to volcanologist of the Red Sismológica Nacional (RSN) – National Seismological Network, Gino Gonzalez, although the Turrialba volcano seismicity has decreased in the last hours, volcanic activity will continue in the coming days.

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
