Aftershocks of 1959 earthquake rocked Yellowstone in 2017-18

University of Utah

A swarm of more than 3,000 small earthquakes in the Maple Creek area (in Yellowstone National Park but outside of the Yellowstone volcano caldera) between June 2017 and March 2018 are, at least in part, aftershocks of the 1959 quake.

From Earth’s deep mantle, scientists find a new way volcanoes form

Cornell University

Far below Bermuda’s pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth’s mantle transition zone – a layer rich in water, crystals and melted rock – can percolate to the surface to form volcanoes.

Major Deep Carbon Sink Linked to Microbes Found Near Volcano Chains

Rutgers University-New Brunswick

Up to about 19 percent more carbon dioxide than previously believed is removed naturally and stored underground between coastal trenches and inland chains of volcanoes, keeping the greenhouse gas from entering the atmosphere, according to a study in the journal Nature. Surprisingly, subsurface microbes play a role in storing vast amounts of carbon by incorporating it in their biomass and possibly by helping to form calcite, a mineral made of calcium carbonate, Rutgers and other scientists found.
