Crustal Responses to the Destruction of Continental Lithosphere: Insights From Radial Anisotropy of the Tanlu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

A Novel Iterative Stable Algorithm for Global Moho Modeling in the Spherical Harmonic Domain

Earth and Space Science
The Mohorovičić discontinuity (Moho) marks the boundary between Earth's crust and the underlying mantle, serving as a critical interface for understanding Earth's structure, composition, and geodynamic processes.

Seismic Imaging Reveals Ongoing Modification of Craton Margins in Northeast Asia

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Cratonic margins are commonly modified, yet the processes responsible remain debated. The Korean Peninsula, situated between adjacent cratons, the Japan Trench, and a back‐arc system, provides a natural setting to investigate this problem. Using 4 years of dense seismic observations, we image upper‐mantle structure beneath the peninsula with P‐

Constrained gravity inversion unravels the Moho depth and tectonic patterns in China and its adjacent areas

Earth and Planetary Physics
The Mohorovicic discontinuity (Moho) boundary separating the Earth’s crust and mantle reflects the evolutionary trajectory of the Earth’s crust, yielding crucial insights into crustal formation, tectonic evolution, and profound dynamic processes. However,

Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins [PDF]

, 2009
Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous,

Stress Field and Megathrust Strength in the Western Hellenic Subduction System: Insights From the 2024 Mw 5.9 Strofades Earthquake Sequence, Greece

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A M5.9 earthquake occurred on 29 March 2024, offshore near the Strofades Islands, in the western Hellenic Subduction System. Here we present high‐precision earthquake locations and focal mechanisms that suggest the rupture of a NNE‐SSW striking, left‐lateral strike‐slip fault.

Suitability of Ground‐Motion Models for Seismic Hazard Assessments in Puerto Rico and the US Virgin Islands

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We perform linear mixed‐effects analyses with a ground‐motion dataset to evaluate how well ground‐motion models (GMMs) fit active crustal, subduction interface, and subduction intraslab earthquakes in Puerto Rico and the US Virgin Islands. Most of the GMMs reproduce the spatial variation in peak ground motions with earthquake magnitude and rupture ...

New Moho depth map for the wider Dinarides region [PDF]

, 2019
We present a new crustal thickness map for the wider Dinarides region. The map was constructed from the results of receiver function analyses on more than 90 seismic stations installed in this area, including the newly available AlpArray stations. Moho depth was measured using two methods, simple H − κ stacking and a more complex inversion process ...

Probing layered arc crust in the Lesser Antilles using receiver functions [PDF]

Royal Society Open Science, 2018
Oceanic arcs can provide insight into the processes of crustal growth and crustal structure. In this work, changes in crustal thickness and composition along the Lesser Antilles Arc (LAA) are analysed at 10 islands using receiver function (RF) inversions

Imaging crustal structure in South-Central Costa Rica with Receiver Functions [PDF]

, 2010
An array of broadband seismometers transecting the Talamanca Range in southern Costa Rica was operated from 2005 until 2007. In combination with data from a short‐period network near Quepos in central Costa Rica, this data is analyzed by the receiver ...
