Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Arenal
A Strombolian eruption is seen here at Arenal on 15 June 1997. The oldest known Arenal products are about 7,000 years old, and the volcano was active for several thousand years contemporaneously with the older Chato volcano (lower right). A recent eruptive period began with a major explosive event in 1968, and frequent explosive activity and slow lava effusion continued through to 2010. Photo by Olger Aragón, 1997.

Conical Volcán Arenal is the youngest stratovolcano in Costa Rica and one of its most active. The 1670-m-high andesitic volcano towers above the eastern shores of Lake Arenal, which has been enlarged by a hydroelectric project. Arenal lies along a volcanic chain that has migrated to the NW from the late-Pleistocene Los Perdidos lava domes through the Pleistocene-to-Holocene Chato volcano, which contains a 500-m-wide, lake-filled summit crater. The earliest known eruptions of Arenal took place about 7000 years ago, and it was active concurrently with Cerro Chato until the activity of Chato ended about 3500 years ago. Growth of Arenal has been characterized by periodic major explosive eruptions at several-hundred-year intervals and periods of lava effusion that armor the cone. An eruptive period that began with a major explosive eruption in 1968 ended in December 2010; continuous explosive activity accompanied by slow lava effusion and the occasional emission of pyroclastic flows characterized the eruption from vents at the summit and on the upper western flank.
