The Sustainability of Free‐Surface‐Induced Supershear Rupture on Strike‐Slip Faults

Geophysical Research Letters, 2019
While prior numerical simulations indicate that the Earth's free surface can induce supershear propagation on strike‐slip faults, copious observations of strike‐slip earthquakes have produced only a few instances of such supershear rupture.

Coseismic surface rupture probabilities from earthquake cycle simulations: influence of fault geometry

Natural Hazards and Earth System Sciences
Earthquake surface ruptures are a significant hazard for critical infrastructure and society. Probabilistic Fault Displacement Hazard Analysis (PFDHA) uses empirical and numerical models to estimate the surface rupture likelihood as the first component ...

Surface ruptures and building damage of the 2003 Bam, Iran earthquake mapped by satellite synthetic apeerture radar interferometric correlation [PDF]

, 2005
We use the interferometric correlation from Envisat synthetic aperture radar (SAR) images to map the details of the surface ruptures related to the 26 December 2003 earthquake that devastated Bam, Iran.

Re-Evaluating the Surface Rupture and Slip Distribution of the AD 1609 M7 1/4 Hongyapu Earthquake Along the Northern Margin of the Qilian Shan, NW China: Implications for Thrust Fault Rupture Segmentation

Frontiers in Earth Science, 2021
The Hexi Corridor is located beyond the northeastern edge of the Tibetan Plateau, and it is bounded by a series of active thrusts along the northern margin of the Qilian Shan and the southern piedmont of the Longshou Shan.

Typical Fine Structure and Seismogenic Mechanism Analysis of the Surface Rupture of the 2022 Menyuan Mw 6.7 Earthquake

Remote Sensing, 2023
On 8 January 2022, a seismic event of significant magnitude (Mw 6.7, Ms 6.9) occurred in the northeastern region of the Tibetan Plateau. This earthquake was characterized by left-lateral strike-slip motion, accompanied by a minor reverse movement.

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...

Coseismic Surface Displacement in the 2019 Ridgecrest Earthquakes: Comparison of Field Measurements and Optical Image Correlation Results

Geochemistry, Geophysics, Geosystems, 2021
A fundamental topic in earthquake studies is understanding the extent to which fault rupture at the surface is localized on primary fault strands as opposed to distributed tens to hundreds of meters away from primary ruptures through off‐fault ...

Predictive Simulation for Surface Fault Occurrence Using High-Performance Computing

GeoHazards, 2022
Numerical simulations based on continuum mechanics are promising methods for the estimation of surface fault displacements. We developed a parallel finite element method program to perform such simulations and applied the program to reproduce the 2016 ...

Rupture of fetal vessels on placental surface [PDF]

Archives of Disease in Childhood, 1971
Six placentae with subamniotic haematomata were studied and the lesions shown to be derived from ruptured varices of surface fetal veins. However, the changes in the vessel walls suggested that these fetal varices had been subjected to an increase of pressure for some time.
