Arenal Volcano, also known as Volcán Arenal, is an active stratovolcano that is located in northwestern Costa Rica. It can be found in Arenal Volcano National Park and was one of Costa Rica’s most active volcanoes until 2010. This volcano has a small crater and several eruptive vents and is the youngest of all active volcanoes in Costa Rica.
Arenal Volcano has produced some violent eruptions, including the eruption of 1968, which covered three villages, killed eighty-seven people, and threw debris as far as 3,280 feet away. The eruptions lasted for a few days and created three new craters in the volcano. The volcano was active between the years of 1975 and 1998, producing lava flows, collapses, explosions, and has emissions. In 1998, a large eruption occurred that caused authorities to close the road connecting the two cities of La Fortuna and Tilarán and evacuated about 450 people from the area. There were no deaths or injuries reported from this eruption, although it was a reported as being very strong. On May 7, 1998, twenty-three eruptions occurred that destroyed an area of green forest and the national park was forced to close. Since these eruptions, Arenal Volcano has been active but quiet.
