Large post-liquefaction deformation of sand: Mechanisms and modeling considering water absorption in shearing and seismic wave conditions

Underground Space
Large deformation of sand due to soil liquefaction is a major cause for seismic damage. In this study, the mechanisms and modeling of large post-liquefaction deformation of sand considering the significant influence of water absorption in shearing and ...

Neotectonic deformation features in plio-pleistocene coastal aeolianites: palaeoseismology and earthquake hazard implications for the Southern Cape, South Africa [PDF]

, 2013
Deformation features within Plio-Pleistocene Bredasdorp Group coastal aeolianites within the Southern Cape, South Africa, have been studied to resolve the neotectonic history of the region, estimate the recent to current upper-crustal stress field, and ...

Monitoring Surface Deformation Before the M7.0 Kumamoto and M6.6 Chitose Earthquakes for Precursor [PDF]

E3S Web of Conferences
Earthquakes have resulted in significant damage; however, the extent of the ground observation coverage remains limited. Thus, a deeper understanding of seismic activity and its precursors holds promise in mitigating earthquake hazards.

Seismic Performance of Steel Elements With and Without FRP Strengthening: A Review [PDF]

SVU-International Journal of Engineering Sciences and Applications
The welded beam-to-column connections in steel moment-resisting frames (MRFs) have long been recognized as a critical structural vulnerability, particularly after the 1994 Northridge earthquake, which exposed their limited plastic rotation capacity and ...

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 ...

Pseudotachylyte Formation in Brittle–Ductile Transition of the Anning River Fault Zone: Implications for Seismic Processes

Applied Sciences
Pseudotachylytes and cataclasites record transient seismic slips within the brittle–ductile transition zone and ductile flow layers. Investigating the mechanisms of pseudotachylytes can provide the most direct geological evidence for revealing seismic ...
