Volcán de Colima is in the Trans-Mexican Volcanic Belt which is a series of volcanic mountains that rise from the high plateaus of central-southern Mexico.
Our earth is very old, an old warrior that has lived through many battles. Nevertheless, the face of it is still changing, and science sees no certain limit of time for its stately evolution. Our solid earth, apparently so stable, inert, and finished, is changing, mobile, and still evolving.

Stratovolcanoes like Volcán de Colima are steep conical mountains characterized by periodic explosive eruptions. Stratovolcanoes have conduits that link them to magma reservoirs deep in the Earth's crust.

Strata is from the Latin stratum meaning laid down. Strato-volcanoes are built from alternating layers of hardened lava, tephra, pumice, and ash.
