It is the Geopark’s major educational event designed to explain the importance of volcanoes and the role they play in the evolution of the Earth. It has a fixed date, August 24, chosen because of its resonance among those passionate about volcanism. On this date, in the year 79, the volcano Vesuvius erupted, destroying the ancient cities of Pompeii and Herculaneum. But beneath the thick layer of lava and volcanic ash, archaeologists have been able to uncover and reconstruct important aspects of the daily life of the ancient world. The guide of the event is Andi Andezit, a nice mascot of the House of Volcanoes made by the volunteers for the Geopark from a piece of volcanic rock – andesite.
