The volcano was dormant for hundreds of years and exhibited a single crater at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it erupted unexpectedly, destroying the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them still exists today. Since October 2010, Arenal’s volcanic activity appears to be decreasing and explosions have become rare, with no explosions reported between December 2010 and October 2012.
Arenal Volcano area is an important watershed for the Arenal Lake Reservoir. The reservoir’s water is used for hydroelectric power. It is also connected to the national system.
