New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Seismic waves reflected as many as four times within Earth's outer core are routinely recorded from large earthquakes. Observations of these waves are confined to rays near grazing incidence on the ...

Earth's structure resembles a giant onion with distinct layers, each playing a crucial role in earthquake formation. The lithosphere comprises the rigid outer shell including the crust and upper ...

Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface. For the decades since ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by Professor John Vidale, was investigating the inner core's rotation – a ...

Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
