Costa Rica Volcanoes – How many are there?

Costa Rica lays on the Pacific Ring of Fire, an area characterized by tectonic movements and collisions, resulting in volcanic activity. There are over 200 volcanic structures in this small country that date back to more than 65 million years ago, however only about 112 show signs of activity. 60 of these volcanoes are considered dormant, which means they are currently not showing any volcanic activity at the moment, but could become active again. 5 of these volcanoes—Arenal, Poas, Rincon de la Vieja, Orosi and Irazu—have only present for about two million years and are considered active.

The rich biodiversity and green landscape that characterizes this country is due greatly to Costa Rica’s volcanoes. As they erupted in the past, they deposited minerals into the soil, making the land fertile and ultimately contributed to the dense forestation that covers the country.
