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

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 ...

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 ...

Earthquakes which occur at depths of several hundred kilometers in the mantle are called “deep-focus earthquakes”. Such earthquakes occasionally result in serious disasters such as the 1994 ...
