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.
Volcano Tours on Hawai'i: The Hawaiian Islands are not only home to the most active volcanoes in the world, Kilauea and Mauna Loa on the Big Island, but also boast a unique natural environment. Born by volcanic activity of a very active hot spot in the middle of the Pacific Plate, they are a showcase of natural history.
Private geology tour on Santorini: We offer you private geology tours to get to know the extraordinary geology and natural history of the island, but also aspects of the deep connection with its cultural history and archaeology.
