Mount Vulture is an extinct volcano located 56 km north of the city Potenza in the Basilicata region (Italy).

The Vulture area lies in the Province of Potenza in the region of Basilicata ( Italy) and comprises the communal territories of Atella Aglianico (pronounced "ah-LYAH-nee-koe" is a black grape grown in the Campania and Basilicata regions of Italy.

With a height of 1326 m, it is unique amongst large Italian volcanoes in being located to the east of the Apennine mountain range. At the summit is a caldera, known as Valle dei Grigi, whose precise origins are disputed. A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption

Volcanic history

The earliest eruptions of the volcano occurred around one million years ago, explosive activity producing ignimbrite. Ignimbrite is a Volcanic Pyroclastic rock often of Dacitic or Rhyolitic composition The explosive eruption phase finished around 830,000 years before present, when the nature of the activity changed to a mix of pyroclastic and effusive, lava eruptions which built up the mountain and which have been dated to around 500,000 years ago. Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures One of the explanations advanced for the Valle dei Grigi is that it is the result of the collapse of a sector of the mountain, as occurred during the 1980 eruption of Mount St. Helens and the 1792 eruption of Mount Unzen. The 1980 eruption of Mount St Helens, a volcano located in Washington state in the United States was a major volcanic eruption. Mount Unzen ( jp 雲仙岳 Unzendake) is an active volcanic complex of several overlapping Stratovolcanoes also known as a Composite volcano

The most recent phase involved further lava flows and the growth of lava domes in the Valle dei Grigi, including the formation of two calderas. In Volcanology, a lava dome or plug dome is a roughly circular Mound -shaped protrusion resulting from the slow eruption of Felsic Lava The most recent activity is thought to have been phreatomagmatic explosions around 40,000 years ago which produced maars and small cold surges. A Phreatic eruption, also called an ultravulcanian eruption, occurs when rising Magma makes contact with ground or surface water A maar is a broad low- Relief Volcanic crater that is caused by a Phreatomagmatic eruption, an Explosion caused by Groundwater A pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some Volcanic eruptions It is similar to a Pyroclastic flow but
