In the late-1980s endemic populations of spruce beetle (Dendroctonus rufipennis) established in the Nine Mile Creek drainage of the Wasatch Plateau following a slope failure event (Dymerski et al. 2001).
Here, quantitative (objective) information (e.g., stand volume) is jointly considered with qualitative (subjective) information (e.g., expert judgment of slope failure event and preference value of a certain stand) to arrive at a compromise plan that considers conflicting management objectives.
All aftershocks east of the mainshock are outer trench slope normal events, but there is also a group of coastal normal events midway between Tokyo and Sendai.
Still, if history is not always written by the winners, it shapes itself to the slope of events: had the episode arrived at a different outcome, as it easily might have, the American rebellion could well have come to be seen as the French Revolution often is, if on a far smaller scale — a folly of Enlightenment utopianism unleashing senseless violence.
Repeated large-scale slope failure events were responsible for the cut-and-fill features forming the Gebra Valley.
Sediment-transport pathways of daily processes such as fair-weather waves can counteract those of monthly or yearly transport processes such as storms or slope failure events.
It is shown that the proposed approach provides proper estimates of occurrence probabilities of slope system failure event and scenario failure events by a single GSS run, which avoids repeatedly performing simulations for each failure event.
The proposed approach decomposes a slope system failure event into a series of scenario failure events representing possible failure scenarios and calculates their occurrence probabilities by a single run of an advanced Monte Carlo simulation (MCS) method, called generalized Subset Simulation (GSS).
It is found that the soil-nail interface modelling can significantly influence the permanent deformation of slope after seismic event.
Results showed that under a rainstorm event, slope failure occurred at a comparably similar time although the antecedent rainfall drainage periods prior to the major rainfall were different (i.e., 24 h, 48 h and 96 h).
