Arenal Volcano Costa Rica

http://www.arenal.net/
Arenal is Costa Rica’s best-known volcano. It’s a stratovolcano – a large,
symmetrical volcano that’s built upon layers of ash, rock and lava – and at 5,437 feet, it stands high above the rest of the countryside. After nearly 400 of years of inactivity, Arenal began erupting in 1968, when it exploded and buried over 5 mi² (15 km²) in rocks, lava and ash. That eruptive cycle took pause in 2010 when the volcano entered into an indefinite resting phrase.
