Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events — and persisting today.
Cratons are pieces of ancient continents that formed several billions of years ago. Their study provides a window as to how processes within and on the surface of Earth operated in the past.
Underwater volcanism on the Earth's crust are active contributors of many different elements to the oceanic environment. Hence, they play an important role in biogeochemical and chemosynthetic cycles of the ocean.

An international team of researchers led by marine geoscientist Dr. Jens Karstens of GEOMAR Helmholtz Centre for Ocean Research Kiel has now, for the first time, combined the latest geophysical and geological methods to resurvey the Minoan eruption, which took place 3,600 years ago, of the Greek island of Santorini.
Hundreds of villagers who live in the shadow of the Western Hemisphere’s deadliest volcano, Colombia’s Nevado del Ruiz, have been on edge for nearly a month ever since the 17,000-foot-tall mountain started spewing plumes of ash and steam high into the atmosphere, indicating that an eruption could be imminent.

Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of these changes lies the powerful force of plate tectonics—the movements of Earth’s crustal plates.
Gas emissions are the manifestation of activity occurring beneath the surface of a volcano. Measuring them lets researchers see what can’t be seen from the surface. This knowledge is vital for hazard monitoring and the prediction of future eruptions.

Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.
