In 1999, about 15,000 people who lived within the range of the Tungurahua volcano in Ecuador were evacuated. They weren't allowed to return home for a year. Since then, the volcanic activity there has been dangerous enough to cause more evacuations, including in 2010 and 2016. Tungurahua is just one recent volcanic eruption included in this book, used as an example of the devastation this natural disaster can cause. The main content, presented in an exciting news magazine style, offers readers a thorough look at how volcanoes form, how scientists use technology to predict eruptions, and terrifying statistics showing volcanoes' aftermath.
