Types of historical lava: Basaltic, basaltic-andesitic

Slamet is composed of two overlapping edifices, an older basaltic-andesite to andesitic volcano on the west and a younger basaltic to basaltic-andesite one on the east.

This low-angle basaltic to basaltic-andesite shield volcano is dotted with more than 400 cinder cones.

Activity began in the Pleistocene with construction of the basaltic-andesite to dacitic Volcán Azufre, followed by formation of basaltic and basaltic-andesite Volcán Planchón, 6 km to the north.

A large basaltic cross sits in the middle of the cemetery.

This type of flow is associated with basaltic lava.

A natural pool sheltered under an impressive basalt arch.

Cerro Verde has produced basaltic-to-andesitic products.

A horizontal basalt flow will therefore develop vertical prisms.

Batet lies on a basalt plateau crowned by the volcano Pujalós.
