TLDR
In this paper, the authors analyzed the triggering mechanisms of submarine landslide initiation for clays with the use of a new simplified model for cliff clays which predicts realistic variations of the stress-strain-strength relationships as well as pore pressure generation during dynamic loading in simple shear.About:

Timing and frequency of large submarine landslides: implications for understanding triggers and future geohazard
TL;DR: The most comprehensive global data set of ages for large (>1 km3) late Quaternary submarine landslides that has been compiled to date has been analyzed in this article, showing that there is no evidence for an immediate influence of rapid sedimentation on slope stability as failures tend to occur several thousand years after periods of increased sedimentation rates.

Late Pleistocene submarine mass movements: occurrence and causes
TL;DR: An extensive study of Late Pleistocene continental slope submarine mass movements was performed in this paper, showing that mass movements are primarily controlled by cyrospheric-induced variations in sedimentation and local sea level.

Mapping basin-wide subaquatic slope failure susceptibility as a tool to assess regional seismic and tsunami hazards
TL;DR: In this paper, a basin-wide mapping of sub-aquatic slope failure susceptibility through time is proposed to evaluate basinwide slope stability through time as a potential tool for regional seismic and tsunami hazard assessments.

Geotechnical in situ characterization of subaquatic slopes: The role of pore pressure transients versus frictional strength in landslide initiation
TL;DR: In this paper, a weak, lightly underconsolidated section of postglacial silty clays overlies overconsolidation fine-grained glacial deposits with coarser components and excess fluid pressure (ca. 2.5× higher than in the hanging wall clay).

Description of Stress-Strain Curves by Three Parameters
Walter Ramberg,William R Osgood +1 more
TL;DR: In this paper, a simple formula is suggested for describing the stress-strain curve in terms of three parameters; namely, Young's modulus and two secant yield strengths.

Simplified procedure for evaluating soil liquefaction potential
H. Bolton Seed,Izzat M. Idriss +1 more
TL;DR: Significant factors affecting the liquefaction (or cyclic mobility) potential of sands during earthquakes are identified, and a simplified procedure for evaluating the potential of sand during earthquakes is presented as mentioned in this paper.

Finite Dynamic Model for Infinite Media
John Lysmer,Roger L. Kuhlemeyer +1 more
TL;DR: In this paper, a numerical method for the dynamic analysis of infinite continuous systems is developed, applicable to systems for which all exciting forces and geometrical irregularities are confined to a limited region and is applicable to both transient and steady state problems.
On the generalized stress-strain behavior of wet clay
TL;DR: The theory of the three-dimensional stress-strain behavior of WET CLAYs was introduced by BURLAND as discussed by the authors, who showed that WETCLAYs are subject to three dimensions of stress and strain.
