Near-Field Across-Fault Seismic Ground Motions
Bulletin of the Seismological Society of America, 2011Abstract There are many engineering applications that require an understanding of the nature of strong ground motions adjacent to and spanning across faults. Unfortunately, such near-field observations at distances less than 100 m of fault rupture are few and incomplete.

Simulation of Rotational ground motion in the near field region
2020<p><strong>&#160;</strong></p><p>In recent times, seismic rotational motions have received significant attention of seismologists as well earthquake engineers. The measurement of rotational motions is useful not only for the complete characterization of the ground ...

Dependency of Near-Field Ground Motions on the Structural Maturity of the Ruptured Faults
Bulletin of the Seismological Society of America, 2009Little work has been undertaken to examine the role of specific long-term fault properties on earthquake ground motions. Here, we empirically examine the influence of the structural maturity of faults on the strong ground motions generated by the rupture of these faults, and we compare the influence of fault maturity to that of other source properties (

Sustainable and Resilient Infrastructure
Iran’s historic railway arch bridges, many over a century old, face seismic risks due to their original design neglecting lateral loads. As they are often situated in seismically active zones near fault lines, understanding their seismic vulnerability is

Stochastic geologic effects on near-field ground motions in alluvium
Bulletin of the Seismological Society of America, 1988Abstract Analysis of accelerograms recorded at the 20 m range from a buried 5-lb detonation in alluvium revealed wide (as large as 20 dB in the amplitude modulus of the Fourier transform) variations in response for frequencies above 35 Hz. Additional experiments were performed which ruled out source asymmetry or instrumental irregularity

Decomposition and Effects of Pulse Components in Near-Field Ground Motions
Journal of Structural Engineering, 2010Long-period pulse components in near-field ground motions have been known to cause significant damage to flexible structures. In this paper, an empirical mode decomposition (EMD) approach is used to identify and separate the dominant pulse, high-frequency, and long-period components in near-field ground motions.

Near-Field Ground Motions from the July 2019 Ridgecrest, California, Earthquake Sequence
, 2020The 2019 Ridgecrest, California, earthquake sequence, including an M_w 6.4 event on 4 July and an M_w 7.1 approximately 34 hr later, was recorded by 15 instruments within 55 km nearest‐fault distance. To characterize and explore near‐field ground motions

Simulation of Near-Field Pulse-Like Ground Motion
2012The accurate prediction of ground motions from possible future earthquakes is the first step toward the robust assessment and mitigation of structural damage against earthquake hazards. The modeling of critical or resonant ground motions has been developed by the present authors in several studies.

Calculations of Near Field, Earthquake Ground Motion
1973Abstract : A stick-slip rupture model has been incorporated into a two- dimensional (plane strain) Lagrangian code with the added feature that rupture initiation is plastic work dependent. Realistic laboratory test data have been used as input to the model.
