"Ash clouds and rivers of orange lava welcome readers to this installment in the Natural Disasters series (6 titles). Through narrative writing and dramatic photos, this high-interest title connects volcano formation to plate tectonics, maps the Ring of Fire, and cites three historic eruptions. A vertical, double-page diagram labels the main parts of a volcano with exciting vocabulary like lava dome and magma chamber. The fourth and final chapter tackles how scientists study volcanoes and includes a visual array of tools, including a tiltmeter, seismometer, thermal imaging device, and ROV (remote operated vehicle for underwater exploration). This is a cursory overview of volcanoes, but the engaging presentation and interesting facts and stats will spark interest in readers and encourage further reading on the subject. A glossary, resource list, and index conclude."
