Geology (1999) 27 (3): 211–214.
...Hervé Philip; Jean-François Ritz Abstract On the basis of analyses of satellite imagery, aerial photographs, and field observations, we describe the occurrence of one of the largest paleolandslides (50 km 3 ) ever recognized in an intracontinental domain. The slide occurred along the active Bogd...

.... Geomorphic and computer stability analyses support the theory that the active Red Creek Landslide is the partial reactivation of a larger, ancient paleolandslide, with a basal rupture surface located predominantly in the Morrison Formation. The original paleolandslide may have been triggered by an earthquake...

Figure 6. Conceptual cross-section of conditions before initial movement of the paleolandslide, as used in the original slope model. The solid line is an estimate of pre-failure topography, and the dotted line is the modern, post-failure topography. Refer to Table 1 for a key to geologic units

...Michael W. Hart Abstract The occurrence of large translational paleolandslides in horizontally bedded sediments can not be completely explained by the presence of "weak" clay rocks and oversteepened natural slopes. When the shear strength of a landslide's basal rupture surface is back-calculated...

... of avalanche movement (e.g., Paguican et al., 2014 ) and could potentially be used to interpret the emplacement velocity of paleolandslide deposits, we objectively mapped hummocks using 1 m contours of the post-event lidar data. Individual hummocks were identified from convex-upward bumps enclosed by 1 m...

Photographs from the hill country portion of the Papatea fault (locations are shown in Fig. 8). (a) Aerial view of the northern end of the Seafront (SF) landslide, white arrows mark the upper and lower margins of the fault‐zone trishear wedge. (b) A scarp that crosses over the back of the Papatea escarpment drainage divide and is thus considered to be tectonic in origin; yellow arrows mark the base of a fenceline that is offset sinistrally. (c) Aerial view of the Limestone Hills (LH) landslide. The Papatea fault cuts obliquely across this hillslope, shown by a black arrow where the bedrock relationship is intact. (d) View to the south looking along the main strand of the fault (denoted by arrows) immediately south of the WQ; ps indicates a paleolandslide deposit at the toe of the slope.

The GBW T‐2 pit was excavated closer to the base of the landslide‐prone slope to intercept more proximal paleolandslide events that might have been shed off the mountain front during Hope fault surface‐rupturing earthquakes.

Neither the paleoclimate record nor a comparison with modern weather-induced landslides supports the concept that the paleolandslides were the result of abnormally wet conditions. The only action capable of inducing widespread, concurrent slope...

For example, paleolandslides that predate Holocene topography might be exposed in modern beach cliffs; fortunately, the pre-Vashon topography...

In other cases, the damage was clearly related to paleolandslide areas, which were probably reactivated by the shaking (e.g., in Casalnuovo Monterotaro, Pietramontecorvino). Because of repeated slidings, the mobilized rock volume has low...
