“…Natural hazards can also affect ecosystems indirectly through secondary events such as accumulation of debris, mudslides and sedimentation that, for example, can cause mangrove mortality (Geertsema et al, 2009;Smith et al, 2009;Zhang et al, 2011).…”

“…Fresh tension cracks were observed up to 21 m behind the headscarp (BGC Engineering Inc. 2008). The damage caused by the landslide-generated displacement wave associated with the Chehalis Lake landslide has previously been briefly described by Geertsema et al (2009) and Stephenson and Rabinovich (2009). The main objective of the research presented in this paper was to characterise the geology, rock mass quality, tectonic structures and the discontinuity sets present at the Chehalis Lake landslide.…”

Stability analysis of the 2007 Chehalis lake landslide based on long-range terrestrial photogrammetry and airborne LiDAR dataAbstract On December 4th 2007, a 3-Mm 3 landslide occurred along the northwestern shore of Chehalis Lake. The initiation zone is located at the intersection of the main valley slope and the northern sidewall of a prominent gully. The slope failure caused a displacement wave that ran up to 38m on the opposite shore of the lake. The landslide is temporally associated with a rain-onsnow meteorological event which is thought to have triggered it. This paper describes the Chehalis Lake landslide and presents a comparison of discontinuity orientation datasets obtained using three techniques: field measurements, terrestrial photogrammetric 3D models and an airborne LiDAR digital elevation model to describe the orientation and characteristics of the five discontinuity sets present. The discontinuity orientation data are used to perform kinematic, surface wedge limit equilibrium and threedimensional distinct element analyses. The kinematic and surface wedge analyses suggest that the location of the slope failure (intersection of the valley slope and a gully wall) has facilitated the development of the unstable rock mass which initiated as a planar sliding failure. Results from the three-dimensional distinct element analyses suggest that the presence, orientation and high persistence of a discontinuity set dipping obliquely to the slope were critical to the development of the landslide and led to a failure mechanism dominated by planar sliding. The threedimensional distinct element modelling also suggests that the presence of a steeply dipping discontinuity set striking perpendicular to the slope and associated with a fault exerted a significant control on the volume and extent of the failed rock mass but not on the overall stability of the slope.

“…According to the European Union Strategy for Soil Protection (COM232/2006), landslides are one of the main eight threats to European soils, especially in mountainous and hilly regions (Lacasse and Nadim 2009). As natural disturbance factors (geological structure, topography, rainfall) or stimulated by human activity, they may raise the geo-and biodiversity of an area (Geertsma et al 2009;Pop and Chitu 2013;Pánek and Lenart 2016). The mass movements are simultaneously material redistribution and erosion processes, which create a complex microtopography, on the one hand, with very dry ridges and hummocks, on the other, sometimes with small areas of standing water in depressions (Pop and Chitu 2013).…”
