44. Plymouth, Montserrat, Britain

This town was once a big draw in the Caribbean where tourists could enjoy some fun in the sun. However, in 1997 everyone was forced to evacuate when volcanic activity threatened the population. It’s a good thing they did; the entire town was buried beneath hot lava.

You’d think that they could come back in once the volcano had finished, but the volcano had other ideas. To this day, it continues to bubble and threaten another massive eruption. Although people are allowed on the island, the majority of Plymouth is off-limits just in case.
