Elba on Sicily — many other destinations could be at serious risk were a volcano ever to erupt. Experts said that volcanic activity shouldn’t scare tourists away from a given location, but they also cautioned that travelers should go into their trips well-informed about the dangers volcanoes can pose.

While it’s no stranger to seismic activity, the capital city of Guatemala’s northern neighbor could be the next victim of a major volcanic eruption. Mexico City is located in a valley within the Trans-Mexican Volcanic Belt, a span of volcanos across the central-southern portion of Mexico. And in recent years, one volcano in particular has prompted concern among residents of Mexico City.
