A research team utilized teleseismic double-difference tomography technology to uncover the morphological changes of the ...

These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale. Xanthippi Markenscoff, a ...

New research provides evidence that fluids play a key role in deep-focus earthquakes -- which occur between 300 and 700 kilometers below the planet's surface. The cause of Earth's deepest ...

The cause of deep-focus earthquakes, however, has been a mystery, because earthquakes occur with the rapid sliding of a fault, which is difficult under the great pressures of the deep mantle ...

Cocooned within the bowels of the Earth, one mineral’s metamorphosis into another may trigger some of the deepest earthquakes ever detected. These cryptic tremors — known as deep-focus ...

Two earthquakes of the same magnitude can cause varying degrees of damage to infrastructure. A deep focal source is expected to inflict less damage than a shallow one. At 10:19 this morning ...

Her focus is reporting on science ... exploring the deep-sea trenches and earthquake site. Deep ocean trenches are long, narrow depressions on the seafloor, reaching deeper into the crust than ...

Transformational faulting of metastable olivine is considered as the main mechanism for deep-focus earthquakes, while the role of water in deep-focus earthquakes remain controversial.

Warren, L. M., E. C. Baluyut, T. Osburg, K. Lisac, and S. Kokkinen, Fault-plane orientations of intermediate-depth and deep-focus earthquakes in the Japan-Kuril ...

“This is very damaging because it has occurred at a shallow depth, so the shockwaves are not dissipated as they go from the focus of the earthquake up to the surface. The buildings received the ...

This study suggests that hypocenters of deep-focus earthquakes are preferentially distributed around the surface of the metastable olivine wedge, which forms the central part of the subducted slab.
