Pompeii
Mt. Vesuvius is an active volcano and has a history of erupting, with the last major eruption in 1944. While it is monitored closely for signs of activity, predicting when it may erupt next is difficult. The chances of Mt. Vesuvius erupting again in the future are considered high due to its active status.
Not at all, it is erupting right now!
