Mt. Vesuvius

The Answer:

Mt. Vesuvius, which erupted in A.D. 79, burying the cities of Pompeii and Herculaneum, killing thousands, is still an active volcano. It has erupted many times since Pompeii was destroyed, including in 1872, 1906, and 1944. Scientists keep close watch over Vesuvius, which has the potential to threaten the sprawling area around Naples, Italy.
