Assessment of variations in shear strain energy induced by fault coseismic slip in deep longwall mining

International Journal of Coal Science & Technology
Shear strain energy is a pivotal physical quantity in the occurrence of earthquakes and rockbursts during deep mining operations. This research is focused on understanding the changes in shear strain energy in the context of retreating longwall mining ...

Slow Fault Slip Signatures in Coseismic Ionospheric Disturbances

Slow Fault Slip Signatures in Coseismic Ionospheric Disturbances
Rise times of earthquake moment release influence the spectra of seismic waves. For example, slow fault movements in tsunami earthquakes excite larger tsunamis than expected from intensities of short-period seismic waves. Here we compare amplitudes of two different atmospheric waves, long-period internal gravity waves and short-period acoustic waves ...

Coseismic Slip and Early Afterslip of the 2024 Hyuganada Earthquake Modulated by a Subducted Seamount

Geophysical Research Letters
Abstract Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction. We inferred coseismic slip and afterslip using geodetic displacements to observationally illustrate the role of subducted seamounts in modulating seismic and ...

Lateral extent of coseismic slip and limited shallow rupture during the 29 July 2025 Kamchatka earthquake illuminated by geodetic and tsunami data

Geoscience Letters
Modern satellite-based geodetic observations reveal the coseismic deformation of the 29 July 2025 moment magnitude 8.8 Kamchatka earthquake, providing valuable constraints on the rupture characteristics along the Kuril-Kamchatka subduction zone ...

Slip rates and coseismic slips analyses along strike-slip faults in Mongolia and Iran - Morphotectonic and paleoseismic approach

, 2010
Ce travail de thèse a pour but d'analyser les variations de vitesses sur des grandes failles décrochantes en contexte intracontinental, capables de produire des séismes de très fortes magnitudes (M > 7.5). Afin d'illustrer ces variations d'activités, cette analyse a été effectuée sur deux zones d'études situées en domaine continental et sismiquement ...
