Volcanoes can produce ash, toxic gases, flashfloods of hot water and debris called lahars, lava flows, and fast-moving flows of hot gases and debris called pyroclastic flows. Some dangers from volcanoes can be predicted ahead of time while others may occur with little or no notice after an eruption. Each volcano and situation is unique. Learn more about volcanic eruptions and pay attention to warnings from local authorities for the best advice available on specific actions you can take to stay safe.
