GEOLOGY

Detailed explanation-1: -Physical volcanologists study the processes and deposits of volcanic eruptions. Geophysicists study seismology (the study of earthquakes-very useful in volcano monitoring), gravity, magnetics, and other geophysical measurements.

Detailed explanation-2: -A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes.

Detailed explanation-3: -Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological, geophysical and geochemical phenomena (volcanism). The term volcanology is derived from the Latin word vulcan. Vulcan was the ancient Roman god of fire.

Detailed explanation-4: -Volcanologists are scientists who watch, record, and learn about volcanoes. They take photographs of eruptions, record vibrations in the ground, and collect samples of red-hot lava or falling ash.
