In the past years these volcanoes suddenly eruptions made huge destructions. Irazu volcanoes is the highest, Arenal is most active and poas has the second widest (diameter 1.5 kilometers) crater in the world. Stratovolcanoes are Costa Rica major volcanic peaks. The type of magma is thick, viscous, and so filled with gases that the erupting magma often blasts violently into the air, fuels by most Drake Bay volcanoes. In 1950's, these volcanoes were decided to be under protection. Many of them are within the National Parks.
