What is the most active volcano in Central America, in terms of eruptions, explosions, lava, gases, etc.? Is it possible to visit it?
There are probably two acceptable answers here:
- Pacaya - an active volcano in Guatemala, it's erupted 23 times since the Spanish conquest of Guatemala. It then erupted in 1965 and has been erupting basically continuously since then.
- Santa Maria - also in Guatemala (which makes it easy for you), which appears on this list of 10 most active volcanoes in the world. While currently the most activity is lahars (mud flows) there are also regular lava flows.
I'd suggest Volcán de Fuego near Antigua in Guatemala. It's active all the time but only at a low level -- great if you want to reliably check out some lava flows without making the evening news. It's just outside of town too, very easy to get to from Antigua which is a great place to visit. Volcán de Agua is also very near by but it's been inactive since the 1500's.
