Volcanoes are found all across the world and the more you travel away from the UK the more you will be exposed to them. There are many different volcanic hazards, including earthquakes, lava flows, ash and pyroclastic flows, each potentially deadly and highly variable. But why do we get these different hazards and what causes them to change? Come help us test what makes lava run faster and see why a steady eruption can suddenly change into a deadly pyroclastic flow!
