Volcanology is the scientific study of volcanoes, their eruptions, and the processes that create them. This field examines the formation of volcanic rocks, the behavior of magma, and the impact of eruptions on the environment and human life. Volcanologists use various tools and techniques to monitor volcanic activity and predict potential eruptions. Researchers in volcanology often study famous volcanoes like Mount St. Helens and Kilauea to understand their behavior. They analyze data from seismic activity, gas emissions, and satellite imagery to assess risks and develop safety measures for communities living near active volcanoes.
