Sources of tsunamis are undersea, underground, and under the microscope in our October issue.
Global broadband seismographic networks have provided the science community with 30 years of data which is being used to understand the Earth.
The role the deep Earth plays in creating topography is hotly debated. A new study uses subtle elevation changes around the globe as evidence that the mantle plays a key role in building topography.
Scientists have long known that the two layers of Earth’s mantle have different chemical compositions. Now, modeling shows that different water concentrations may keep them from mixing.
Scientists have found holes filled with minerals that indicate fluid-filled pores exist many tens of kilometers below Earth’s surface. But no, The Core fans, you still can’t get amethyst-laden geodes in the mantle.
Mantle rocks in Papua New Guinea contain curious geochemical signatures that scientists have traditionally interpreted as evidence of billions-year-old melting. New evidence suggests otherwise.
Fundamental questions on subsurface properties are robustly addressed through probabilistic assessment of multiple forward/inverse modelling formalisms using interrogation theory.
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
Helium isotopes found in water samples provide a snapshot of what lies beneath the plateau and stimulate debate within the geosciences community.
