Photograph taken on the west side of Arenal Volcano where the jungle along the slopes has not been destroyed by eruptions. The darker area above the volcano is ash mixing with the clouds.

This is the west side of Arenal Volcano where there has been extensive volcanic activity. On July 29, 1968 a large pyroclastic flow buried 9.3 square miles (15 sq km) killing at least 87 people and burying small villages – note the dead trees that remain from the eruption. The darker area above the volcano is ash mixing with the clouds.


Arenal Volcano lava flow

A small steaming lava flow on the flank of Arenal Volcano – the lava cools into rock when it is exposed to the air but continues to push forward forming a wall of rock with lava inside.

Arenal Volcano lahar

Many hot springs exist around Arenal Volcano which create the steam. A lahar or mud flow has destroyed a path through the jungle as it opened out on the plain in the foreground.

A view from Arenal Lake of Arenal Volcano. Note where the volcano has destroyed most of the jungle on this side of the volcano.

Arenal Volcano is an extremely active volcano which has been continuously erupting for decades. There is a good chance that you will experience a phreatic eruption (trapped steam being released in the crater) during a visit. But keep your distance. The volcano is extremely dangerous and has taken many lives.

Arenal Volcano is a volcanic arc-related volcano formed from the subduction of the Cocos Plate below Central America. As the plate plunges below the crust, hydrous fluids are released into the mantle which initiates melting causing a series of volcanoes along the western edge of Central America including Arenal Volcano.

Arenal Volcano has probably formed over the last 7,000 years but recently was dormant until it sprang to life in 1968 killing 87 people along its eastern flank. The volcano has had major eruptions in 1968, 1975, 1984, 1993, 1994, 1996, and twice in 1998. The volcano has become less active since about 2010 but eruptions and lava flows at night can still be witnessed.


Description


Arenal Volcano

Arenal Volcano National Park (Spanish: Parque Nacional Volcán Arenal) is a Costa Rican national park in the central part of the country, forming the Arenal Tilaran Conservation Area. The park encompasses the Arenal Volcano, the most active in the country, which had previously been believed to be dormant until a major eruption in 1968. It neighbours Lake Arenal, which is the site of the country's largest hydroelectricity project, the Lake Arenal Dam.
