Characteristics of surface ruptures produced by recent major earthquakes on the Tibetan Plateau and its surrounding areas, and their tectonic implications

Dizhi lixue xuebao
Objective  Coseismic surface ruptures provide key evidence for identifying the seismogenic structures of earthquakes, elucidating crustal deformation mechanisms, and assessing seismic hazards.

Coseismic surface deformation analyses using SAR and optical images: 2023 Kahramanmaraş earthquake sequence, Türkiye

Turkish Journal of Earth Sciences
The 2023 Kahramanmaraş earthquake sequence in Türkiye, including Mw 7.7 and 7.6 mainshocks, caused significant surface ruptures along the East Anatolian Fault (EAF) and Sürgü–Çardak Fault (SCF). We calculated the coseismic displacement fields through pixel offset tracking (POT) analysis of Sentinel-1 SAR data and optical image correlation (OIC ...

The 2010–2011 South Rigan (Baluchestan) earthquake sequence and its implications for distributed deformation and earthquake hazard in southeast Iran [PDF]

We investigate the source processes and tectonic significance of two earthquakes that occurred on 2010 December 20 (Mw 6.5) and 2011 January 27 (Mw 6.2) within a desert region south of the town of Rigan, SE Iran. The two earthquakes, which we refer to as

Understanding creep in sandstone reservoirs – theoretical deformation mechanism maps for pressure solution in granular materials [PDF]

, 2014
Subsurface exploitation of the Earth’s natural resources removes the natural system from its chemical and physical equilibrium. As such, groundwater extraction and hydrocarbon production from subsurface reservoirs frequently causes surface subsidence and

TEM characterisation of near surface deformation resulting from lubricated sliding wear of aluminium alloy and composites [PDF]

, 2007
Aluminium alloy composites have been extensively investigated for use in tribo-contact applications, however little detailed literature exists on the sub-surface microstructural evolution as a result of lubricated sliding wear.

Northward rupture and early afterslip of two graben-bounding normal faults during the 2025 Dingri earthquake of Tibet

Communications Earth & Environment
The Mw 7.0 Dingri earthquake, the largest documented normal-faulting event in southern Tibet, struck within the NS-trending Dinggye-Xainza Rift system. Here we combine field observations, high resolution optical and synthetic aperture radar imagery and ...
