“…Such PGA maps are available for most of the seismically affected regions through the Global Seismic Hazard Assessment Project [278]. In the literature, there are some models for earthquake-induced landslides (see a review in [279]), where PGA maps are used as input of the model [280,281]. The validation of the results showed that the ensemble model could provide good prediction rates.…”

Landslides represent major natural hazards, which cause every year significant loss of lives and damages to buildings, properties and lifelines. In the last decades, a significant increase in landslide frequency took place, in concomitance to climate change and the expansion of urbanized areas. Remote sensing techniques represent a powerful tool for landslide investigation: applications are traditionally divided into three main classes, although this subdivision has some limitations and borders are sometimes fuzzy. The first class comprehends techniques for landslide recognition, i.e., the mapping of past or active slope failures. The second regards landslide monitoring, which entails both ground deformation measurement and the analysis of any other changes along time (e.g., land use, vegetation cover). The third class groups methods for landslide hazard analysis and forecasting. The aim of this paper is to give an overview on the applications of remote-sensing techniques for the three categories of landslide investigations, focusing on the achievements of the last decade, being that previous studies have already been exhaustively reviewed in the existing literature. At the end of the paper, a new classification of remote-sensing techniques that may be pertinently adopted for investigating specific typologies of soil and rock slope failures is proposed.

“…Between 1811 and 1997, a total of 76 earthquake events have been documented (Keefer 1984;Rodriguez et al 1999), resulting in more than 100,000 number of landslides. Wasowski et al (2011) provided a thorough review of previous, current, and future research studies pertaining to the topic of earthquake-induced landslides. In general, the analysis of dynamic responses and deformations in slopes can be performed by numerical integration (Newmark 1965;Wilson and Keefer 1983;Chang et al 2005), numerical simulation (Wakai et al 2009;Zhang et al 2012), and physical modeling (Wartman et al 2005;Wang and Lin 2011).…”

“…The movement of the fault belt caused a rupture in central faults and created a zone of disturbance of over 300 km in length (Huang and Li 2009a, b). There were about 56,000 rockfalls and landslides triggered directly by the Wenchuan Earthquake, forming 256 barrier lakes (Huang and Li 2009a, b;Xu et al 2009;Yin et al 2009;Qi et al 2010;Wasowski et al 2011).…”

The Guantan landslide, with a total displaced mass of about 468 9 10 4 m 3 , was triggered by the 2008 Wenchuan earthquake and succeeding rainfall in Jushui Town, Sichuan Province, China. The landslide occurred on an anti-dip hard rock slope with a weak rock founding stratum of 200 m in thickness. To investigate the failure mechanism of the Guantan landslide, dynamic behaviors of hard and soft rock slopes were investigated by means of large scale shaking table tests. The laboratory models attempted to simulate the field geological conditions of the Guantan landslide. Sinusoidal waves and actual seismic waves measured from the Wenchuan Earthquake were applied on the slope models under 37 loading configurations. The experimental results indicated that deformation mainly developed at a shallow depth in the upper part of the hard rock slope and in the upper (near the crest) and lower (near the toe) parts of the soft rock slope. An equation for predicting the depth of sliding plane was proposed based on the location of the maximum horizontal acceleration. Finally, it was concluded that the failure process of the Guantan landslide occurred in three stages: (1) toppling failure caused by compression of the underlying soft rock strata, (2) formation of crushed hard rock and sliding surface in soft rock as the result of seismic shocks, particularly in the horizontal direction, and (3) aftershock rainfall accelerates the process of mass movement along the sliding plane.

“…The analysis of earthquake-triggered landslide inventories was initiated by Keefer (1984) who performed a statistical analysis The 21 September 1999, Mw 7.5 Chi-chi earthquake in Taiwan resulted in a landslide inventory map that is comprised of 9,272 landslides interpreted from SPOT images (Liao and Lee 2000;Liao et al 2002). Furthermore, this inventory has also been used extensively to compare various landslide controlling factors with the landslide distribution (Weissel and Stark 2001;Wang et al 2003;Lin and Tung 2004;Lee et al 2008;Khazai and Sitar 2004) and geomorphology evolution in a part of the earthquake-affected area (Dadson et al 2003(Dadson et al , 2004(Dadson et al , 2005Hovius et al 2009Hovius et al , 2011Harp et al 2011a;Wasowski et al 2011). In addition, Wang et al (2002) reported the numbers of landslides to be approximately 26,000 (Wasowski et al 2011) when landslides of smaller size are included.…”
