Central America sits on the western edge of the Caribbean tectonic plate, and volcanoes in Guatemala, El Salvador, Nicaragua, Costa Rica, and Panama form an inland volcanic arc.
The Atlantic Ocean fits our general idea of how plate tectonics works–“big crack” in the middle, with seafloor spreading towards the Americas on one side and Europe and Africa on the other. There’s a lot more going on in the Caribbean. And it involves volcanism and earthquakes, both of which are capable of kicking up a tsunami in this part of the world.

Two volcanoes named Fuego make the news frequently. This post is about the beautiful but dangerous volcano in Guatemala and its quiet neighbor Acatenango.
Why does the same volcanic zone produce two kinds of volcanoes?
