Name(s) in local language(s):
(Spanish) VolcΓ‘n Arenal
An active stratovolcano, approximately 1,670 metres high. The age is approx. 7500 years.
ArenΓ‘l had been inactive in human memory and was assumed to be extinct. (The story is told that a pupil in a nearby school referred to ArenΓ‘l as a volcano in a written assignment and the teacher corrected it, saying that ArenΓ‘l is just a mountain, not a volcano.) Later geologic investigations found that its most recent activity had been early in the 15th century and had erupted more or less every 1000 years since first emerging around 7500 years ago.
In July 1968 the volcano erupted violently with a lateral blast directed westward that leveled three villages and, over the next several days, killed a total of 87 people and uncounted head of livestock. For the next 40 years ArenΓ‘l was one of the most active volcanoes on Earth, frequently producing several explosive events daily. Lava and tephra issuing from the new vent on the west flank of the old cone build a new cone that had exceeded the height of the old cone by the early 1990s. Activity gradually shifted from explosive events to lava flows, and by about 2010 ArenΓ‘l was regarded as having returned more or less to dormancy.
