Seismic characteristics of supershear and sub‐Rayleigh earthquakes: Implication from simple cases
Geophysical Research Letters, 2017 Numerous investigations of supershear earthquakes make a conclusion that a supershear earthquake produces a seismic shock wave on the ground that may increase the resulting destruction. We investigate a supershear rupture promoted by the free surface and

The Relationship of Small Earthquakes to Strain Accumulation Along Major Faults in Southern California [PDF]
, 1983 Fault-plane solutions for recent small (ML ≤ 4.6) earthquakes in the central Transverse Ranges, California, were determined using an azimuthally-varying crustal model.

Toward Exascale Earthquake Ground Motion Simulations for Near-Fault Engineering Analysis [PDF]
Computing in Science & Engineering, 2017 Modernizing SW4 for massively parallel time-domain simulations of earthquake ground motions in 3D earth models increases resolution and provides ground motion estimates for critical infrastructure risk evaluations. Simulations of ground motions from large (M ≥ 7.0) earthquakes require domains on the order of 100 to500 km and spatial granularity on the ...

Dimensional response analysis of multistorey regular steel MRF subjected to pulselike earthquake ground motions [PDF]
, 2010 An alternative and efficient procedure to estimate the maximum inelastic roof displacement and the maximum inelastic interstorey drift ratio along the height of regular multi-storey steel MRF subjected to pulse-like ground motions is proposed. The method

LiDAR and Paleoseismology Solve Earthquake Mystery in the Pacific Northwest, USA
Geophysical Research Letters, 2021 One of the largest historical earthquakes in the U.S. Pacific Northwest occurred on December 15, 1872 near the south end of Lake Chelan. Lack of recognized surface deformation suggested that the earthquake occurred on a blind, perhaps deep, fault.

Research on Near-Fault Problems in Earthquake Engineering
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012 The state-of-the-art of near-fault problems in earthquake engineering is comprehensive reviewed. Strong ground motions in the near-fault region exhibit several new characteristics, which cause the attentions of both seismologists and engineers who zealously studied these ground motions during the last two deceases.

Interaction of piled foundation with a rupturing normal fault [PDF]
, 2013 Post-seismic observations in the 1999 Kocaeli earthquake in Turkey have indicated that piled foundations may be less suitable than stiff mat foundations in defending a structure against a major normal fault rupturing underneath.
