The Indian Ocean Geoid Low ranks as the largest negative "gravity hole" anomaly on Earth, which is why the “thumbprint” jumps ...

In some parts of Earth's interior, seismic waves travel at different speeds depending on the direction in which they are ...

(a) Tectonic setting background in the Tonga-Lau-Fiji region. (b) Schematic diagram of the upper mantle structure beneath the Tonga-Lau-Fiji region. A landmark study published in Geoscience—a leading ...

SANTA CRUZ, CA–For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps ...

Rhythmic pulses of molten rock are rising beneath eastern Africa, according to a new study. The pulsing plume of hot mantle beneath Ethiopia, driven by plate tectonics, is slowly pulling the region ...

The layer of molten rock corresponds with the upper mantle, also known as the asthenosphere. Illustration: cigdem (Shutterstock) Earthquakes and volcanic eruptions are a result of the movement of ...

The rising mantle does more than just flow. It brings heat and pressure to the surface, where it causes volcanoes to form and earthquakes to strike. The way these upwellings move and shift helps ...
