Inversion of Moho topography in Taiwan using improved Parker-Oldenburg method

Frontiers in Earth Science
Taiwan is located at the junction between the Philippine Sea Plate and the Eurasian Plate, with intense tectonic movements in the region. A more accurate Moho topography model is significant for the study of the intrinsic genesis within Taiwan’s orogenic

Adaptive linear inversion of Moho topography in the Tibetan Plateau by combining gravity and seismic data

Frontiers in Earth Science
The Tibetan Plateau is a region where the Indian and Asian-European plates collide. A high-precision Moho topography model is important for the study of plate motion and internal tectonics of the Tibetan Plateau.

Determining the Moho topography using an improved inversion algorithm: a case study from the South China Sea

Frontiers in Earth Science
The Parker-Oldenburg method, as a classical frequency-domain algorithm, has been widely used in Moho topographic inversion. The method has two indispensable hyperparameters, which are the Moho density contrast and the average Moho depth.

Three‐dimensional Moho topography in Italy: New constraints from receiver functions and controlled source seismology [PDF]

Geochemistry, Geophysics, Geosystems, 2011
In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on

Moho topography, ranges and folds of Tibet by analysis of global gravity models and GOCE data. [PDF]

Sci Rep, 2015
AbstractThe determination of the crustal structure is essential in geophysics, as it gives insight into the geohistory, tectonic environment, geohazard mitigation, etc. Here we present the latest advance on three-dimensional modeling representing the Tibetan Mohorovičić discontinuity (topography and ranges) and its deformation (fold), revealed by ...

Crustal thickness variations beneath Egypt through gravity inversion and forward modeling: linking surface thermal anomalies and Moho topography

Progress in Earth and Planetary Science
This study aims to quantify the topography of the Moho boundary, the lower crust and uppermost mantle contact of Egypt, in order to estimate the crustal thickness variation and its link to the distribution of thermal anomalies under Egypt.

Moho depth inferred from gravity and topography in an intraplate area (Iberian Chain) [PDF]

Tectonophysics, 2016
This paper discusses variations in Moho depth beneath an intraplate area, including the Iberian Chain thrust belt and the surrounding Cenozoic basins, based on topography and Bouguer anomaly data analysis. Two models of Moho depth mapping were used: Airy Moho depth maps and a Moho depth map derived from the Bouguer anomaly map.

Moho Geometry Estimation Beneath the Gulf of Guinea From Satellite Gravity Data Based on a Regularized Non‐Linear Gravity Inversion

Earth and Space Science, 2023
In this work, we present a new gravimetric Moho model over the Gulf of Guinea computed from the inversion of the global gravity EIGEN‐6C4 model. The computation procedure contains a regularized non‐linear inversion algorithm.

A recovered Moho model by integrated inversion of gravity and seismic depths in Iran

Heliyon, 2020
This research aims to define the depth of Moho in Iran by collocation method using gravimetric data with seismic information. The definition of the Moho in the Iranian region is of considerable importance due to the geological complexity of the area also

Moho topography in the central Andes and its geodynamic implications

Earth and Planetary Science Letters, 2002
P-to-S converted waves at the continental Moho together with waves multiply reflected between the Earth’s surface and the Moho have been used to estimate the Moho depth and average crustal Vp/Vs variations in the central Andes. Our analysis confirms and significantly complements the Moho depth estimates previously obtained from wide-angle seismic ...
