“…This method evaluates the ultimate displacement by computing the ground motion acceleration at which the inertia force becomes high enough to cause yielding, and by integrating the acceleration that exceeds the yield acceleration on the slide mass. Huang et al (2001) used Newmark's displacement method to calculate the free body motion of Jih-Feng-Erh-Shan landslide blocks during the Chi-Chi Earthquake, showing that the block slid when the peak acceleration exceeded the yield acceleration. The freebody diagram in Fig.…”

Tsaoling is located in Southwestern Taiwan, 10 km east of the frontal thrusts of the mountain belt. Five large historical landslide events were recorded from 1862 to 1999. No details of the earliest landslide event (1862) are available, thus this paper deals with the 1941 landslide event. Using the Particle Flow Code in two dimensions (PFC 2D) to simulate the mechanism of the Tsaoling landslide in 1941, this study shows that the landslide block developed cracks and slid down 0.2-1.8 m on the sliding plane. The cracks concentrated in certain zones, which corresponded to future landslide detachment planes. During the vibration simulation, the cracks spread from the shear plane to ground surface. Monitoring the variations of the displacements, velocity, and stress during vibration simulation showed that the peak velocity and stress in the transition zones occurred at 3 s. The displacement of the left part of the block exceeded 1.3 m, and the displacement of the right part was less than 1.3 m during vibration simulation. These results suggest that the left part of the block was pushed down by the right part, ultimately inducing a landslide during an earthquake.

“…For example, among the 224 earthquake faults listed in Wells and Coppersmith (1994), which occurred between 1856 and 1993, 75 % were single-slip and 25 % were oblique-slip. In addition, the following earthquakes that occurred in the last decade and triggered landslides were also mainly either reverse-or thrust-slip: 1999 ChiChi earthquake, Taiwan (Huang et al 2001;Shou and Wang 2003;Khazai and Sitar 2004;Chang et al 2005); 2002 Avaj earthquake, Iran (Mahdavifar et al 2006); 2004 Niigata Ken Chuetsu earthquake, Japan (Sato et al 2005;Chigira and Yagi 2006;Kieffer et al 2006;Wang et al 2008a, b); and 2005 Kashmir earthquake, Pakistan (Owen et al 2008). The 2002 earthquake in Alaska that triggered landslides was associated with the Denali fault, which is one of the longest strike-slip systems in the world , although during the earthquake slips along the fault rupture were oblique-slips with predominant strikeslip components Dreger et al 2004;Velasco et al 2004).…”

Predictive mapping of susceptibility to earthquake-triggered landslides (ETLs) commonly uses distance to fault as spatial predictor, regardless of style-of-faulting. Here, we examined the hypothesis that the spatial pattern of ETLs is influenced by style-of-faulting based on distance distribution analysis and Fry analysis. The YingxiuBeichuan fault (YBF) in China and a huge number of landslides that ruptured and occurred, respectively, during the 2008 Wenchuan earthquake permitted this study because the style-of-faulting along the YBF varied from its southern to northern parts (i.e. mainly thrust-slip in the southern part, oblique-slip in the central part and mainly strike-slip in the northern part). On the YBF hanging-wall, ETLs at 4.4-4.7 and 10.3-11.5 km from the YBF are likely associated with strike-and thrust-slips, respectively. On the southern and central parts of the hanging-wall, ETLs at 7.5-8 km from the YBF are likely associated with obliqueslips. These findings indicate that the spatial pattern of ETLs is influenced by style-of-faulting. Based on knowledge about the style-of-faulting and by using evidential belief functions to create a predictor map based on proximity to faults, we obtained higher landslide prediction accuracy than by using unclassified faults. When distance from unclassified parts of the YBF is used as predictor, the prediction accuracy is 80 %; when distance from parts of the YBF, classified according to style-of-faulting, is used as predictor, the prediction accuracy is 93 %. Therefore, mapping and classification of faults and proper spatial representation of fault control on occurrence of ETLs are important in predictive mapping of susceptibility to ETLs.

“…The typhoon caused an unexpectedly high cumulative rainfall (up to 1994 mm within 2 days, measured at Alisan rainfall station near the headwater of the watershed) and caused over thirty debris-flows (Jan and Chen, 2005); 27 people were declared dead and 14 missing. The 1999 Chi-Chi earthquake with a moment magnitude M w = 7.6, on 21 September 1999, was the largest in Taiwan for 50 yr and the largest on the Chelungpu thrust fault in 300-620 yr (Shin and Teng, 2001;Chen et al, 2001;Dadson et al, 2004;Huang et al, 2001) and caused significant effects on the watershed. After the Chi-Chi earthquake, the extremely heavy rains brought by Typhoons Toraji and Nali in 2001 caused numerous debris flow events in central Taiwan (Cheng et al, 2005), and resulted in over 100 people dead or missing and major damage to houses, roads, bridges, and dikes.…”

Abstract. This study analyzed the variability in the number of rainfall events related to debris-flow occurrence in the Chenyulan stream watershed located in central Taiwan. Rainfall data between 1970 and 2009 measured at three meteorological stations nearby/in the watershed were collected and used to determine the corresponding regional average rainfall for the watershed. Data on debris-flow events between 1985 and 2009 were collected and used to study their dependence on regional average rainfall. The maximum 24-h regional rainfall R d was used to analyze the number of rainfall events N r , the number of rainfall events that triggered debris flows N d , and the probability of debris-flows occurrences P . The variation trends in N r , N d and P over recent decades under three rainfall conditions (R d > 20,230, and 580 mm) related to debris-flow occurrence were analyzed. In addition, the influences of the Chi-Chi earthquake on N d and P were presented. The results showed that the rainfall events with R d > 20 mm during the earthquakeaffected period (2000)(2001)(2002)(2003)(2004) strongly responded to the increases in the average number of rainfall events that triggered debris flows and the average probability of debris-flows occurrences. The number of rainfall events with R d > 230 mm (the lower boundary for the rainfall ever triggering debris flow before the Chi-Chi earthquake), and R d > 580 mm (the lower boundary for extreme rainfall ever triggering numerous debris flows) in the Chenyulan stream watershed increased after 2000. The increase in the number of extreme rainfall events with R d > 580 mm augmented the number of rainfall events ever triggering numerous debris flows in the last decade. The increase in both the number of rainfall events that ever triggered debris flows and the probability of debrisflow occurrences was greater in the last decade
