Discussion on the magnitude or intensity limitation of paleoearthquake events

Dizhi lixue xuebao, 2023
The magnitude is an important parameter that characterizes the size of earthquakes. However, in paleoearthquake studies, it is difficult to precisely determine the rupture parameters closely related to seismic moment, making it challenging to directly ...

Characteristics of ∼40 Ma Mafic Rocks in North Tibet and Their Tectonic Implications

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Several magmatic belts are present in the Tibetan Plateau. Among these, the Qiangtang magmatic belt in North Tibet remains elusive. In particular, the petrogenesis, magma source, and tectonic implications of the ultramafic to mafic rocks in the North Qiangtang area are underinvestigated due to their sparsity and remoteness.

Hydrogeochemistry of Fault-Related Hot Springs in the Qaidam Basin, China

Applied Sciences, 2023
Hydrogeochemical characterization studies are regarded as an important method for determining the origin of hot springs. The major elements, trace elements, and stable isotopes of four groups of hot spring water samples and two groups of gas samples ...

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Rapid slip along the central Altyn Tagh Fault: Morphochronologic evidence from Cherchen He and Sulamu Tagh

Journal of Geophysical Research: Solid Earth, 2004
To better constrain the ongoing rates of deformation in northern Tibet, the ages of fluvial and glacial geomorphic markers left‐laterally displaced by the Altyn Tagh Fault have been determined by radiocarbon and 10Be‐26Al cosmic ray exposure dating. Two sites were investigated: Cherchen He and Sulamu Tagh, both near Tura (∼37.6°N, 86.6°E).

Tectonic Deformation Analysis with ALOS-Based Digital Elevation Models in the Longshou Shan Mountains (NW China)

GeoHazards
The Longshou Shan area is located on the northeastern margin of the Tibetan Plateau in northwest China. The study area is located where the sinistral Altyn Tagh and Haiyuan Faults overlap and the Qilian Shan thrust fault systems in the northeastern ...

Bimodal Structural Evolution of the Mantle Lithosphere and Crust During Continental Shortening: Development of the Eurekan Orogen

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The enigmatic Eurekan Orogeny of northeastern Ellesmere Island in the Canadian arctic was formed as a result of mountain‐building processes in the Paleogene. In this work, we use numerical geodynamical experiments alongside regional geological interpretation to investigate the tectonic evolution of the Eurekan, and explore how shortening ...

Evidence for Mesozoic shear along the western Kunlun and Altyn‐Tagh fault, northern Tibet (China) [PDF]

Journal of Geophysical Research: Solid Earth, 2003
The strike‐slip faults of north Tibet accommodate part of the Cenozoic convergence between India and Asia. Along the Karakax valley south of Yecheng and near the Xidatan trough south of Golmud, the active traces of the Altyn‐Tagh and Kunlun faults follow narrow belts of metamorphic rocks.

The seismicity in the middle section of the Altyn Tagh Fault system revealed by a dense nodal seismic array

Earthquake Research Advances
The left-lateral Altyn Tagh Fault (ATF) system is the northern boundary of the Qinghai-Xizang Plateau, separating the Tarim Basin and the Qaidam Basin.

Coseismic Slip and Early Rapid Afterslip of the 2025 MW 7.7 Myanmar Earthquake Constrained by Space‐Based Geodetic Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 destructive Myanmar earthquake ruptured the previously recognized seismic gap along the Sagaing fault, with the longest ever recorded surface ruptures (∼ ${\sim} $500 km). Here, we use SAR and optical images to characterize coseismic and early postseismic deformation of this event.
