Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]

, 2012
The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least

Effects of fault finiteness on near-source ground motion [PDF]

, 1981
Near-source ground motion at four azimuths but constant epicentral range is computed from a buried circular strike-slip fault in a half-space. Particle acceleration, velocity, and displacement at each station on the free surface is computed in the ...

Critical earthquake response of a SDOF elastic‐perfectly plastic model with viscous damping under double impulse as a substitute for near‐fault ground motion

, 2018
The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure with viscous damping under the ‘critical double impulse’ is derived.

Assessing extent of building damage following an earthquake: case study of the 2023 Turkey-Syria doublet

npj Natural Hazards
An earthquake doublet (M w 7.8 and M w 7.5) struck southeastern Turkey on February 6, 2023, causing widespread devastation. To evaluate seismic damage across 11 provinces, we analysed strong motion data, developed fragility functions and building damage ...

Data-Driven Simulation of Near-Fault Ground Motions Using Stationary Wavelet Transform and Hilbert Analysis

Buildings
Near-fault ground motions exhibit significant characteristics such as velocity pulses, rupture directivity, and strong vertical components, which pose serious threats to structural safety.

Critical Response of Single-Degree-of-Freedom Damped Bilinear Hysteretic System under Double Impulse As Substitute for Near-Fault Ground Motion

Frontiers in Built Environment, 2018
A double impulse input is used as a substitute for near-fault earthquake ground motions. A closed-form expression is derived in the maximum elastic-plastic response of a single-degree-of-freedom (SDOF) damped structure with bilinear hysteresis under the ‘

Slip in the 2010–2011 Canterbury earthquakes, New Zealand [PDF]

, 2012
The 3rd September 2010 Mw 7.1 Darfield and 21st February 2011 Mw 6.3 Christchurch (New Zealand) earthquakes occurred on previously unknown faults. We use InSAR ground displacements, SAR amplitude offsets, field mapping, aerial photographs, satellite ...

A Study on the Sloshing Problem of Vertical Storage Tanks under the Action of Near-Fault Earthquakes

Advances in Civil Engineering, 2020
In this study, through a vibration table test, finite element simulation, and research on the rationality of the wave-height fortification of national storage tank specifications, the sloshing response of vertical storage tanks under the action of near ...

Stability of pulse-like earthquake ruptures [PDF]

, 2019
Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating under steady-state conditions can be efficiently analysed theoretically, but ...

Effect of a Near Fault on the Seismic Response of a Base-Isolated Structure with a Soft Storey

Slovak Journal of Civil Engineering, 2017
This study focuses on the soft-storey behavior of RC structures with lead core rubber bearing (LRB) isolation systems under near and far-fault motions.
