MOHO DEPTHS VERSUS GRAVITY ANOMALIES

Survey Review, 1999
AbstractIsostatic gravity anomalies are the best suited anomalies for different geodetic applications, such as the interpolation and the geoid determination. Different isostatic hypothesis are discussed and used to compute the depths of the Mohorovic˘ie discontinuity (Moho depths).

The depth of Moho in the mainland of China

Acta Seismologica Sinica, 1995
In the last decade, deep seismic sounding (DSS) of profiles several ten thousand kilometers in length has been conducted in the mainland of China. A lot of results published in Chinese were compiled and a map of Moho depth was presented in this paper. Coverage of DSS profile is not uniform, and is lacking in some areas, especially in the western part ...

A new Moho depth model for Fennoscandia and surroundings

2020
<p>Seismic data are the preliminary information for investigating Earth’s interior structure. Since large parts of the world are not yet sufficiently covered by such data, products from Earth satellite gravity and altimetry missions can be used as complimentary for this purpose. This is particularly the case in most

Moho depth, seismicity and seismogenic structure in China mainland

Tectonophysics, 2014
Abstract The study of the crust–upper mantle structure based on wide-angle seismic profiles performed in China mainland since 1958, has provided tighter constraints on the architecture and deformation of the lithosphere; but the link between the seismic velocity structure and the seismogenic layer of the crust is still an open problem in which we are

Moho depth in Antarctica from seismic data

Izvestiya, Physics of the Solid Earth, 2011
A refined digital model of the Moho depth is constructed for the Antarctica on a uniform grid with resolution of 1° × 1°. The model is based on seismic data. Results are presented as a digital table that defines the Moho depth (the Moho, or M) at each point.

IMPLEMENTING SEISMIC MOHO DEPTHS IN GEOID COMPUTATION

Survey Review, 2003
AbstractThe paper studies the effect of implementing seismically estimated Moho depths in gravimetric geoid computation, instead of assuming an isostatic hypothesis to create the compensating masses, within the well-known remove-restore technique of geoid computation.

Moho depth variation in Taiwan from teleseismic receiver functions

Journal of Asian Earth Sciences, 2010
We determine lateral variation of Moho discontinuity, crustal thickness, and Vp/Vs ratios in the vicinity of Taiwan by analyzing all the available teleseismic waveform data collected by the Broadband Array in Taiwan for Seismology network from 1998 to 2004.

Determining Moho Depth beneath Sedimentary Basins Using Regional Pn Multiples

Bulletin of the Seismological Society of America, 2019
The study of the Moho beneath thick sedimentary basins involving natural earthquakes is challenging, as low‐velocity materials often cause strong reverberations that mask Moho signals. Here, we develop a method to determine the depth of the Moho by taking advantage of the presence of the sediments. The method utilizes the first Pn crustal multiple from

Moho depth estimation of northern of East African Rift System

Journal of Applied Geodesy, 2023
Abstract The northern part of the East African Rift System is characterized by depleted Moho depth and thermally thinned lithosphere. This research aims to determine the Moho depth of the study area through non-linear gravity inversion and cross-validation with seismic Moho estimates. The study utilized gravity data to obtain the gravity

Moho depth of Qinghai-Tibet plateau revealed by seismic probing

Journal of Earth Science, 2009
The Qinghai (青海)-Tibet plateau is the newest and biggest orogenic belt in the world and a natural laboratory for researching continental geodynamics, such as continent-continent collision, convergence, subduction, and plateau uplift. From the 1950s to the present, there have been many active-source (deep seismic sounding and deep seismic reflection ...
