Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, the exact forms of manganese, their abundance and the mechanisms behind ...

A seismic wave generated by Japan's devastating 2011 magnitude 9.0 Tohoku-Oki earthquake travelled nearly 2,900 kilometres to ...

Scientists have discovered that seismic waves traveling to Earth’s core and back caused almost all of Japan to shift eastward after the 2011 earthquake.

Strange seismic wave arrivals from a 2010 earthquake under Spain were the clues that led to an unexpected discovery beneath the western Mediterranean: a subducted oceanic slab that has completely ...

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 ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

Record-setting storms in 2023 filled California's major reservoirs to the brim, providing some relief in a decades-long drought, but how much of that record rain trickled underground? Shujuan Mao of ...

In March 2011, the magnitude 9 Tohoku earthquake struck off the northeast coast of Honshu, Japan. Violent ground shaking lasted for about six minutes and triggered a massive tsunami, ultimately ...

Images show the (a) shear deformation cell assembly and (b) microstructure of a shear-deformed δ-AlOOH aggregate deformed at 20 GPa and 950 °C, corresponding to lower mantle transition zone conditions ...
