Volcanologists. View of a team of volcanologists arriving at Klyuchevskoy volcano by helicopter. The volcano's crater can be seen at centre. Klyuchevskoy is an active volcano on Russia's Kamchatka peninsula. Volcanology (or vulcanology) is the scientific study of volcanoes. There are many important types of data to be collected, including recording seismic tremors, measuring the gas content and temperature of the lava, and determining the volcano's recent history by studying rock and lava formations. Information such as this can help predict future eruptions, which can save lives and property.
