g A010) Stratovolcanoes - Mt. Vesuvius, Italy. Fly to Mt. Vesuvius in Italy and turn on the Pompeii Pyroclastic Flow tour (run the tour twice to let the imagery load). Use the Ruler tool to determine the distance (in km) from Mt. Vesuvius to the excavated ruins of the city of Pompeii (which was buried by volcanic ash and pyroclastic material from Mt. Vesuvius during the eruption of 79 C. E.) If a nuée ardent(pyroclastic surge) accompanies the next eruption of Mt. Vesuvius and it travels at 300 km/hr, how many minutes would it take to reach the site of ancient Pompeii?
