Europe's volcanoes provide unique information about the history of Italy. Mount Vesuvius, a stratovolcano, last erupted in March 1944, located in southern Italy. In 79 AD, Mount Vesuvius erupted covering the city of Pompeii in molten lava, ash, pumice volcanic blocks, and toxic gases. The entire eruption lasted 12 to 18 hours. Afterwards, everything was perfectly preserved and fossilized by the volcanic ash and has provided valuable information about the Roman culture. Also, in Italy, Stromboli volcano, a stratovolcano, last erupted in July 2019. In 2013, a team of researchers led by Ingrid Smet and Dr. Tom Pfeiffer, volcanologists, discovered dinosaur fossil footprints, from Diplodocus hallorum, in thick layers of ash.
