The earthquake probabilities of the Liupanshan fault zone based on the Coulomb stress and friction constitutive law

Geomatics, Natural Hazards & Risk
As the forefront of the northeastern margin of the Tibetan Plateau, the Liupanshan area is subjected to significant Cenozoic deformation. Considering the background of historical earthquakes and the current seismic activity, the Liupanshan fault poses a ...

A possible characteristic of foreshocks derived from the evaluation of loading/unloading induced by earth tides

Frontiers in Earth Science, 2022
The detection of the potential of a larger event immediately after a moderate earthquake is a quite difficult problem. In this work, we devised an approach to determine whether an earthquake is a foreshock to a larger mainshock by evaluating loading ...

Soil gas CO2 emissions from active faults: a case study from the Anninghe—Zemuhe fault, Southeastern Tibetan Plateau, China

Frontiers in Earth Science, 2023
Introduction: Carbon dioxide emissions from non-volcanic areas are undervalued in the carbon cycle.Methods: First estimates of diffuse CO2 flux from the Anninghe—Zemuhe fault (AZF), Southeastern Tibetan Plateau, China, which suggests this could equal 15%

Uneven aftershock distribution of Wenchuan Ms8.0 earthquake and possible mechanism

Geodesy and Geodynamics, 2011
The aftershock activity of Wenchuan Ms8.0 earthquake showed different spatial and temporal distributions along two different segments of the Longmenshan fault. This difference was likely the result of segmentation of the earthquake rupture process, which
