Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

Abstract: Seismic interpretation is a crucial task in geophysics, requiring accurate prediction of subsurface layer thickness and seismic wave velocity. Traditional methods are computationally ...

When an earthquake rupturing along a fault hits a barrier, it creates a seismic signature called the “stopping phase.” ...

Scientists have mapped how Earth’s deepest mantle is being deformed—and the results point to long-lost tectonic plates buried ...

Scientists discover hidden "ghost plume" that is so powerful that it is physically warping the internal layers of the planet ...

As the Moon swallowed the Sun during the April 8, 2024, total solar eclipse, something remarkable happened on the ...

The H/V spectral ratio (HVSR) method, an extension of Nakamura’s (1989) technique, is widely used to evaluate subsoil properties from ambient noise and has also been applied to earthquake recordings ...

A massive water reservoir has been discovered hidden 700 kilometers beneath Earth’s surface, trapped inside a mineral called ringwoodite. The volume of water locked away in this deep reservoir is ...

Abstract: Multilayer interior permanent magnet synchronous machines (IPMSMs) are preferred for high-speed operations and reducing rare earth magnet materials. The use of a hybrid magnet arrangement in ...

An undersea magnitude -7.4 earthquake toppled buildings in parts of northern Indonesia, sent people fleeing from their homes, killed at least one person and generated a small tsunami Thursday. Waves ...

NASA armed astronauts with grenades and space mortars not to fight, but to crack open the moon's deepest secrets. What they found buried beneath the surface raised more questions than answers. Hungary ...
