Arenal Volcano in Costa Rica

Arenal Volcano is a 1,633 meter (5,300 feet) high mountain, which is perfectly conically shaped with a crater of 140 meters. It is known as a stratovolcano – a tall, symmetrical volcano that’s built upon successive layers of rock, ash and lava. Arenal’s most recent eruptive period began in 1968 with an explosion that buried three small villages and left 87 people dead. Up until July 2010, the eruptions had been constant, though much less severe—there were effusions of smoke and lava on an almost daily basis.
