Robledo volcano is a 6-km wide caldera in NW Argentina, located 80 km SW of the much larger and better known Cerro Galán caldera.
It contains Cerro Blanco del Robledo lava dome on the southern rim of the caldera. There are extensive rhyolitic pumice-fall deposits around the dome. Older, but well-preserved pyroclastic-flow deposits underly the lava dome of Cerro Blanco and are exposed on the floor of the caldera and on its NW flanks.
Satellite surveys in the 1990 have shown subsidence of the Robledo caldera.
Stromboli volcano photos: The lighthouse of the Thyrrhenian Sea - thanks to its typical, regular explosions that coined the term "strombolian activity", Stromboli is one of the most famous and photogenic volcanoes in the world.
Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
