Liquefaction Triggering Model for Subduction Zone Earthquakes
Liquefaction is one of the major causes of ground failures during an earthquake. Recent evidence shows that the existing variants of the "simplified" liquefaction evaluation procedure lead to inaccurate results for megathrust earthquakes in subduction interfaces. To overcome this drawback and to …

Use of Cone Penetration Testing in the Interpretation of Ground Shaking From Paleoliquefaction Evidence
To evaluate seismic hazard in regions of infrequent earthquakes it is often necessary to rely on evidence left from earthquakes that occurred before seismographs were available. This evidence can consist of human observations or of evidence left in the geologic record. The New Madrid Seismic Zone …

Application of Fatigue Theories to Seismic Compression Estimation and the Evaluation of Liquefaction Potential
Earthquake-induced liquefaction of saturated soils and seismic compression of unsaturated soils are major sources of hazard to infrastructure, as attested by the wholesale condemnation of neighborhoods surrounding Christchurch, New Zealand. The hazard continues to grow as cities expand into …

Assessment of the Cyclic Strain Approach for the Evaluation of Initial Liquefaction
… and energybased based approaches. The existence of a volumetric threshold shear strain, γtv, under which there is no development of excess pore pressures, and the unique relationship between pore pressure ratio and cyclic shear strain, γc, make a compelling argument for using a strain-based …
