"This thickened area is like a fossilized fingerprint of an ancient piece of seafloor that subducted into the Earth ...

The core-mantle boundary (CMB) is a crucial interface within the Earth, marking the boundary between the outer core and the ...

St. Helens. Most of the subducting plate continues into the mantle, perhaps to reappear much later at a distant divergent boundary.

1. Figure 1: Map of the northern Cascadia subduction zone showing the distribution of earthquakes in the subducting Juan de Fuca plate and the locations of seismic cross-sections. Green dashed line ...

These pockets could then get pushed around the mantle by other slabs of subducting crust, which poke into Earth's interior like stirring sticks into a smoothie. Better understanding these ULVZs ...

Researchers showed that the 1995 Kobe (Hyogo-ken Nanbu) earthquake, which struck southern Hyogo Prefecture, may have been triggered by deep underground flooding beneath Arima Hot Springs. By analyzing ...

indicating upward fluid migration from sources along the subducting Pacific plate. The fluid-rich zones in the crust seem to coincide with some of the strike-slip faults of the region. Wannamaker ...

A possible source of the water is the oceanic tectonic plate, which is moving from beneath the Pacific and subducting toward greater depths beneath the Japanese archipelago. Seawater enters cracks ...

Koshun Yamaoka, an emeritus professor of seismology at Nagoya University, said the temblor is believed to have occurred near the boundary between the land plate and the subducting Philippine Sea ...
