It is the major educational event of the Geoparc designed to explain the importance of volcanoes and the role they play in the evolution of the Earth. It has a fixed date, August 24th, chosen because of its resonance among volcanism enthusiasts, because in the year of 79 A.D., the Vesuvius volcano erupted, destroying the ancient cities of Pompei and Herculaneum. But beneath the thick layer of lava and volcanic ash, archaeologists have been able to discover and reconstitute important aspects of the daily life of the ancient world.

Guide to the event is Andi Andezit, the mascot of the Volcano House, made by the volunteers of Geoparc from a volcanic andesite rock.
