Control of tectonic inheritance on continental intraplate strain rate and seismicity

, 2018
International audiencePresent-day deformation and seismicity of continental lithosphere are characterized by a first-order dichotomy between Plate Boundary Zones (PBZ) and Stable Continental Regions (SCR).

Melt Production and Volatile Release From Thermochemical Mantle Plumes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Insights Into Intraplate Stresses and Geomorphology in the Southeastern United States

Geophysical Research Letters, 2019
The stress field in the eastern United States is commonly considered to be broadly uniform and due to homogeneous far‐field forces; however, modern and geologic stress indicators in this region show substantial heterogeneity.

Studying local earthquakes in the area Baltic-Bothnia Megashear using the data of the POLENET/LAPNET temporary array [PDF]

Solid Earth, 2016
Earthquakes in areas within continental plates are still not completely understood, and progress on understanding intraplate seismicity is slow due to a short history of instrumental seismology and sparse regional seismic networks in seismically non ...

Tracing Mantle Upwellings Beneath Changbaishan/Mount Paektu: New Insights From Transition Zone Discontinuity Structure

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intraplate volcanism in Northeast Asia, located in a distant back‐arc setting, challenges conventional models of mantle convection and volatile cycling. Using receiver function data from over 300 broadband stations, we image the mantle transition zone (MTZ) beneath the Changbaishan/Paektu volcano.

Seismicity and regional tectonics of the Estremadura, Southwestern Portugal [PDF]

, 1989
The RESTE Project was an integrated geophysical-geological study of the Estremadura, southwestern Portugal. The core of the programme consisted of the acquisition and analysis of microearthquake data.

The Causative Fault of the 2016 Mwp 6.1 Petermann Ranges Intraplate Earthquake (Central Australia) Retrieved by C- and L-Band InSAR Data

Remote Sensing, 2018
On 21 May 2016, an Mwp 6.1 earthquake occurred along the Petermann Ranges in Central Australia. Such a seismic event can be classified as a rare intraplate earthquake because the affected area presents low seismicity, being at the center of the Indo ...

Automatic GNSS Coordinate Time Series Analysis for Very Large Networks

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract We present a new algorithm, AutoCF, for automatically constructing coordinate functions (CFs) for continuously operating GNSS reference stations (CORSs). The iterative algorithm alternates between application of LASSO and Ridge Regression methods, with hyperparameters successively tightened with each iteration to more judiciously scrutinize ...
