WebAug 2, 2024 · In the upper mantle Vs model constructed by Jiang et al. the subducting plate is most prominent at depths until 390 km depth, but weaker fast anomalies appear in the MTZ. In the P-wave velocity model for North America by Burdick et al. the end of the slab seems to penetrate into the lower mantle, but resolution is lost at greater depth. WebThe mantle lies beneath the crust to a depth of about 2900km. The mantle has many layers within the upper and lower mantle. The upper layer is the lithosphere below which is the asthenosphere. The transition zone is the layer between the upper and lower mantle distinguished by the 410 km and 660 km discontinuities, as revealed by seismic evidence.

According to these results, it is suggested that the rupture areas of large earthquakes (>M7) in this region are limited within the contact zone between the NEJ arc crust and the subducting oceanic crust.

WebThis region of the mantle is called the transition zone between upper and lower mantle. Earlier Earth models ( Jeffreys and Bullen, 1940; Gutenberg, 1959 ) indicate changes in the velocity gradients at these depths, although without resolving first-order discontinuities, based on observations of slowness changes and increasing P wave amplitudes at about … The lower mantle, historically also known as the mesosphere, represents approximately 56% of Earth's total volume, and is the region from 660 to 2900 km below Earth's surface; between the transition zone and the outer core.
