Robert I. Tilling (born 1935) is an American geologist and volcanologist who spent a long career studying volcanic hazards at the United States Geological Survey. Public sources indicate that his work was closely tied to monitoring volcanic activity and assessing hazards, a professional background that is directly reflected in his writing for general audiences. The database holds one work by him, Volcanoes, a popular introduction to volcanology that explains how volcanoes form, the types of eruptions, and their impact on human society, balancing scientific accuracy with readability. Given the available material, public information about his life is limited; his influence lies chiefly in translating specialist volcanological knowledge into accessible writing that helps readers understand the real-world significance of volcanic hazards.
