An eruption Monday by the Volcán Turrialba went 1.2 kilometers into the sky, said the Instituto Costarricense de Electricidad, which is involved in monitoring such activity. That’s about three-quarters of a mile above the crater.
The volcano is among just 15 percent that remain active for an extended period, said the state firm, which is part of the Red Sismológica Nacional.
The mountain has been fairly calm since Dec. 7. It began its eruptive phase in 2010 and has attracted the attention of international experts.
The acid rain and ash has damaged the agricultural area in the vicinity.
It also has damaged tourism because there is a two-kilometer prohibited zone around the mountain and the national park bearing the volcano’s name has been closed.
