Volcanoes are unpredictable and their eruptions can have devastating consequences. Some go thousands of years without erupting before suddenly reigning fire on anyone unfortunate enough to be nearby.
Throughout history they have caused disasters around the world,with one of the most deadly eruptions ever being the infamous Mount Vesuvius in Italy in 79 A.D, which is thought to have killed up to 15,000 people.
When it erupted, it spat out gases and molten rock obliterating settlements in the vicinity including Pompeii.
