Finite difference methods have become a cornerstone in the simulation of seismic wave propagation, providing a robust numerical framework to approximate the differential equations that govern seismic ...

Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, a seismic wave was recorded by two distant seismic stations. Now, researchers argue that similar ...

A common geoscientific misconception is that land-based shear-wave (S-wave) seismic data accounts for only a small percentage of the total amount of compressional-wave (P-wave) data acquired in ...

Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to reveal potential earthquake precursors by monitoring the stress state of ...

The difference in water content between the lithosphere and the upper layer of Earth’s mantle can explain the observed seismic changes The oceanic lithosphere, which constitutes the top layer ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

ultra-low velocity layer '' with a diameter of about 1000 km at 2900 km underground in the Marquesas Islands located in the Pacific Ocean. Presented by the research team of the university. Among the ...

An earthquake originating from Alaska caused seismic waves to penetrate the innermost inner core of the Earth. (Credit: Drew Whitehouse, Son Phạm and Hrvoje Tkalčic) Planet Earth is a marvelous ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...
