Background:The eruption of the trachytic Green Tuff ignimbrite about 55,000 years ago was followed by caldera formation. The high point on the island, 789-m-high Monte Epemeo, is a volcanic horst composed of the Green Tuff ignimbrite deposit that was submerged after its eruption and then uplifted. Volcanism on the island has been significantly affected by tectonism that formed a series of horsts and grabens; at least 800 m of uplift has formed as a result of resurgent doming during past 33,000 years. Many small monogenetic volcanoes were formed around the uplifted block. Volcanism during the Holocene produced a series of pumiceous tephras, tuff rings, lava domes, and lava flows. The latest eruption of Ischia, in 1302 AD, produced a spatter cone and the Arso lava flow, which reached the NE coast. Source: Smithsonian GVP |
