Mount Vesuvius, Italy
From December 16th to December 17th, 1631, Mount Vesuvius threatened everyone in the Gulf of Naples region in Campania when it erupted. Though the eruption of 79 AD was considered far greater in magnitude, the region’s denser population in 1631 likely led to a greater number of fatalities. Between ash clouds, falling rock, lava flow, and mudflows, the eruption was extremely dangerous. The number of fatalities varies dependent on the source, but the 1631 eruption of Mount Vesuvius is believed to have killed anywhere from 3,000 to 6,000 people, making it the worst volcanic disaster in the Mediterranean at the time.
