A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions, collect eruptive products including tephra, rock and lava samples. One major focus of inquiry in recent times is the prediction of eruptions to alleviate the impact on surrounding populations and monitor natural hazards associated with volcanic activity. Geologists who research volcanic materials that make up the solid Earth are referred to as igneous petrologists.
Harry Hammond Hess was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics. He published theories on sea floor spreading, specifically on relationships between island arcs, seafloor gravity anomalies, and serpentinized peridotite, suggesting that the convection in the Earth's mantle is the driving force behind this process.
Grenville Turner is a research professor at the University of Manchester. He is one of the pioneers of cosmochemistry.
Wallace "Wally" Smith Broecker was an American geochemist. He was the Newberry Professor in the Department of Earth and Environmental Sciences at Columbia University, a scientist at Columbia's Lamont–Doherty Earth Observatory and a sustainability fellow at Arizona State University. He developed the idea of a global "conveyor belt" linking the circulation of the global ocean and made major contributions to the science of the carbon cycle and the use of chemical tracers and isotope dating in oceanography. Broecker popularized the term "global warming". He received the Crafoord Prize and the Vetlesen Prize.

Kliti Grice, is a chemist and geochemist known for her work in identifying geological and environmental causes for mass extinction events. Her research integrates geological information with data on molecular fossils and their stable carbon, hydrogen and sulfur isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of modern and ancient aquatic environments and biodiversity hot spots. This information expands our understanding of both the Earth's history and its current physical state, with implications ranging from energy and mineral resource exploration strategies to environmental sustainability encompassing climate dynamics and expected rates, durations and scale of our future planet's health. As one of the youngest women professors in Earth Sciences, she is the founding director of the Western Australian Organic and Isotope Geochemistry Centre (WA-OIGC) and is a Professor of Organic and Isotope Geochemistry at Curtin University in Perth, Western Australia.
Janne Blichert-Toft is a geochemist, specializing in the use of isotopes with applications in understanding planetary mantle-crust evolution, as well as the chemical composition of matter in the universe. To further this research, Blichert-Toft has developed techniques for high-precision Isotope-ratio mass spectrometry measurements.
Marie Edmonds is a Professor of volcanology and Earth Sciences at the Department of Earth Sciences at the University of Cambridge whose research focuses on the physics and chemistry of volcanic eruptions and magmatism and understanding volatile cycling in the solid Earth as mediated by plate tectonics. She is interested in the social and economic impacts of natural hazards; and the sustainable use of Earth's mineral and energy resources. Professor Edmonds is the Vice President and Ron Oxburgh Fellow in Earth Sciences at Queens' College, Cambridge; and the Deputy Head of Department and Director of Research at the Earth Sciences Department, University of Cambridge.
