Stratovolcano
Arenal is the youngest stratovolcano in Costa Rica and one of its most active. Arenal's most recent eruptive period began with a major explosive eruption in 1968. The eruption of Arenal volcano on July 29–31, 1968, after centuries of dormancy, produced three new fissural craters.
Volcanic activity since 1968 has included explosive activity, slow lava effusion and occasional pyroclastic flows.
Stage 1 eruptions from 1968–1971 were from a closed system. Stage 2 eruptions from 1971–current were produced from an open system.
