Volcanology

Definition

Volcanology is the study of the generation and movement of molten rock on Earth and other planetary bodies, primarily through volcanoes and volcanic eruptions. This encompasses the generation of magma, its geochemistry and movement through the Earth’s crust, the physics of volcanic eruptions and hazards including ash clouds and pyroclastic flows

    Estimates of carbon in the deep mantle vary by more than an order of magnitude. Coupled volcanic CO2 emission data and magma supply rates reveal a carbon-rich mantle plume source region beneath Hawai'i with 40% more carbon than previous estimates.

    The long-term cooling of Earth's mantle is recorded in the declining temperature and volume of its volcanic outpourings over time. However, analyses of 89-million-year-old lavas from Costa Rica suggest that extremely hot mantle still lurks below.

    Over 70% of the volcanism on Earth occurs beneath an ocean veil. Now, robotic- and fibre-optic-based technologies are beginning to reveal this deep environment and identify subaqueous volcanoes as rich sources of sulfur, carbon dioxide and life.

    The climatic response to the eruption of the Samalas Volcano in 1257 has been elusive. Medieval archives tell of a spatially variable reaction, with Europe and Japan experiencing severe cold compared to relative warmth in North America.
