Water plays an important role in most processes within the Earth's mantle, eg transport
phenomena, differentiation and seismic properties. This paper reviews the various aspects …

In this article, we review the significant recent results of geophysical studies and discuss
their implications on seismotectonics, magmatism, and mantle dynamics in East Asia. High …

This study reevaluates the adiabatic temperature profile of the Earth's mantle. The global
average temperature at the 410‐km discontinuity is estimated to be 1839 (38) K by …

We present the first seismic image of the upper mantle beneath the active intraplate
Changbai volcano in Northeast Asia determined by teleseismic travel time tomography. The …

A variety of atypical plume-like structures and focused upwellings that are not rooted in the
lower mantle have recently been discussed, and seismological imaging has shown …

A high-resolution P-wave tomography of the crust and mantle down to 700km depth beneath
the Japan Islands is determined using a large number of high-quality arrival-time data from …

We present new pieces of evidence from seismology and mineral physics for the existence
of low-velocity zones in the deep part of the upper mantle wedge and the mantle transition …

The origin of intraplate volcanoes in Northeast Asia is considered to be associated with
upwelling of hot and wet asthenospheric materials in the big mantle wedge above the …

In situ X‐ray diffraction study of post‐spinel transformation in hydrous peridotite (2 wt.%
H2O) indicates that the phase boundary is shifted to higher pressures by 0.6 GPa relative to …

Data from seismology and mineral physics indicate the existence of low-velocity zones in the
deep part of the upper mantle wedge and the mantle transition zone under East Asia (Zhao …
