“…Currently the highest landslide frequency along the southwest coast of British Columbia occurs during the autumn (Jakob & Lambert 2009). Models predict that on average, a 10% increase in 4 week antecedent rainfall and a 6% increase in 24-hour precipitation can be expected by the end of the next century (Jakob & Lambert 2009). This increased level of soil saturation during autumn suggests landslides will occur even more frequently than they do currently, but it is not clear what the magnitude of this increase will be.…”

“…Most models agree that there will be large seasonal changes, especially toward wetter autumns and drier summers (Climate Impacts Group 2009;Jakob & Lambert 2009). The regional models also predict increases in extreme high precipitation over the next half-century, especially in the Puget Sound area (Climate Impacts Group 2009).…”

“…As a result, researchers are becoming more and more interested in understanding possible correlations between slope instabilities and climate change (Collison et al, 2000;Jaedicke et al, 2008;Jakob and Lambert, 2009). Particular attention has been focused on the role played by permafrost degradation, and the consequent thawing of the ice filling the rock joints (Fischer et al, 2006;Gruber and Haeberli, 2007;Chiarle and Mortara, 2008;Huggel, 2009).…”

Abstract. Rockfalls are common instabilities in alpine areas and can cause significant damage. Since high mountains have been affected by an increasing number of these phenomena in the last years, a possible correlation with permafrost degradation induced by climate change has been hypothesized.To investigate this topic, a monitoring system, made of 5 triaxial geophones and 1 thermometer, was installed in 2007 at the Carrel hut (3829 m a.s.l., Matterhorn, Northwestern Alps), in the frame of the Interreg IIIA Alcotra project n. 196 "Permadataroc".The preliminary data processing relates to the classification of recorded signals, the identification of the significant microseismic events and the analysis of their distribution in time and space. The first results indicated a possible correlation between clusters of events and temperature trend, and a concentration of events in specific sectors of the rock mass.Research is still in progress. The recording of data for a longer period is planned to fully understand seasonal trends and spatial distribution of microseismic activity, and possible relations with permafrost degradation. Nevertheless, the preliminary observations prove that the monitoring system can detect noises generated by rock slope deformation. Once fully developed, this technique could become a helpful tool for early warning and preliminary stability assessments.

“…These studies showed some relationships between debris-flow triggers and (1) an increase in the number of intense rainfall events and/or (2) glacier retreat and permafrost degradation due to an increase in temperatures. However, the hydrologic response of debris flows to climate is complex (Jakob and Lambert, 2009). The relationships between rainfall changes and debris-flow occurrences differ regionally since there are differences in regional responses to global climate change.…”

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
