“…Recent studies reveal high tectonic activities of the Shanchiao normal fault, including geomorphic and geologic analysis by borehole investigation and record Huang et al, 2007;Song et al, 2000), by the geodetic study (Yu et al, 1999), by the micromorphological study (Chen et al, 2006), and by geomorphological study (Chang et al, 2010). The results show that the normal faulting slip rate is estimated between 8.2 and 1.8 mm yr −1 in subsidence at different sites and in time intervals (Huang et al, 2007;Chen et al, 2010).…”

“…The estimation of landslide volume indicates the minimum volume in this study. Finally, the total cut volume of the CSL and XSL was calculated to be at least 820 ± 20 × 10 6 m 3 , covering an area of approximately 7 km 2 ; this volume is approximately 6 times larger than that of the largest landslide ever reported in Taiwan (Chen et al, , 2006.…”

“…Consequently, quantitative studies have been successfully conducted for delineating landslides; determining risks (Gritzner et al, 2001), landslide morphology (Glenn et al, 2006;Staley et al, 2006;Santangelo et al, 2015b), and activity Chang et al, 2006); estimating cut-and-fill volumes Chen et al, 2006;Chan et al, 2012;Hsieh et al, 2016); and performing geological mapping (Yeh et al, 2014). In this study, an Optech ALTM3070 apparatus was used to record the positions of the laser reflecting points with a rate of up to 71 000 pulses per second when we conducted the Central Geological Survey project in 2005.…”

“…The cut-and-fill volumes of a landslide can be estimated using two digital terrain models (DTMs): one before the landslide and one thereafter Chen et al, 2006;Chan et al, 2012;Hsieh et al, 2016). The information derived using the DTMs can facilitate the identification and estimation of landslide activity and evolution.…”

Abstract. Several remote sensing techniques, namely traditional aerial photographs, an unmanned aircraft system (UAS), and airborne lidar, were used in this study to decipher the morphological features of obscure landslides in volcanic regions and how the observed features may be used for understanding landslide occurrence and potential hazard. A morphological reconstruction method was proposed to assess landslide morphology based on the dome-shaped topography of the volcanic edifice and the nature of its morphological evolution. Two large-scale landslides in the Tatun volcano group in northern Taiwan were targeted to more accurately characterize the landslide morphology through airborne lidar and UAS-derived digital terrain models and images. With the proposed reconstruction method, the depleted volume of the two landslides was estimated to be at least 820 ± 20 × 10 6 m 3 . Normal faulting in the region likely played a role in triggering the two landslides, because there are extensive geological and historical records of an active normal fault in this region. The subsequent geomorphological evolution of the two landslides is thus inferred to account for the observed morphological and tectonic features that are indicative of resulting in large and life-threatening landslides, as characterized using the recent remote sensing techniques.

“…The results are either vectors between two points (or common areas) or distances between two data sets (point to surface comparison) either in a user-defined direction or as shortest distance (Hausdorff distance) between the two surfaces. This difference calculation allows for the computation of volume differences, as is discussed by different authors (Bitelli et al 2004;Chen et al 2006;Corsini et al 2007;Teza et al 2007;Dewitte et al 2008;Jaboyedoff et al 2009a;Prokop and Panholzer 2009;Mueller and Loew 2009;Avian et al 2009;Baldo et al 2009). …”

Use of LIDAR in landslide investigations: a review

et al. 2010

This paper presents a short history of the appraisal of laser scanner technologies in geosciences used for imaging relief by high-resolution digital elevation models (HRDEMs) or 3D models. A general overview of light detection and ranging (LIDAR) techniques applied to landslides is given, followed by a review of different applications of LIDAR for landslide, rockfall and debris-flow. These applications are classified as: (1) Detection and characterization of mass movements; (2) Hazard assessment and susceptibility mapping; (3) Modelling; (4) Monitoring. This review emphasizes how LIDARderived HRDEMs can be used to investigate any type of landslides. It is clear that such HRDEMs are not yet a common tool for landslides investigations, but this technique has opened new domains of applications that still have to be developed.

Pliocene sedimentary rocks of about 130 Mm 3 in volume slid along bedding planes dipping by 14°, with an average speed of about 35 m/s, during the Tsaoling landslide. We conducted friction experiments to reproduce the initiation processes of this landslide, by idealizing landslide movements during the earthquake as accelerating/decelerating motion. Experiments were done on shale from the field, at 3 MPa normal stress corresponding to the overburden pressure. Results indicate that the accelerating/decelerating motion causes weakening and strengthening at each oscillation cycle and results in overall slip weakening which can be approximated as an exponential slip weakening. Behaviors during oscillatory slip are fairly similar to those during sliding at constant slip rates. Newmark analysis with measured frictional properties reveals that the landslide can be triggered with wet gouge properties, but the landslide motion stops with parameters for dry shale gouge. Delayed initiation of the landslide is consistent with a survivor's witness.
