Recently, the students in iRALL School 2017 had finished the left courses in Beichuan base and got certificates smoothly.


On October 21, Prof. Steve Evans introduced some typical large landslide cases to the students, including the ones with mud sandstone as bedrock, the relationship between large landslide and barrier lake, and the large landslides formed in glacial environment. Physical simulation and case comparison are adopted to analyze their genetic mechanisms, focusing on the degree and frequency of landslides.



Zhu Huanchun, senior expert in rock mechanics from Itasca Group, made a brief introduction on the mechanism of collapse from three aspects: force condition, fracture zone, and geological structure. Then, he described the numerical simulation process of landslide, including parameter selection, modeling and simulation, and result analysis.



On that afternoon, Prof. Fan Xuanmei gave a lecture titled “Landslide Accidents in Wenchuan Earthquake”, including four parts: quantitative analysis on geohazard, control factors, potential hazards, monitoring and early warning of debris flow, through a large number of clear live videos and simulation videos. At the end of her class, she emphasized the difficulties and challenges of the early warning of hidden landslides in high altitude and densely covered areas,taking the Xinmo large landslide in 2017 as the case study.



Then four doctoral students made their presentations on respective researches.


Muhammad Shafique, from Pakistan, introduced the sensitivity analysis of landslides in northern Pakistan along the “Belt and Road”; GUILLE DOMÈNECH, from Spain, introduced the risk assessment of rockfall, taking the "Montserrat Massif landslide" as the background; Emma Cody, from Australia, introduced “Ice marginal Landslide”; finally, Yang Gengchao, from Hong Kong University, used the pure numerical simulation to show the dynamic multi-phase simulation process of debris flow.




On October 23, Dr. Wang gonghui expounded typical cases of the landslides induced by earthquakes, old landslides, rainfall, groundwater levels and air pressure. He also introduced a series of researches on these typical cases they have done. Among them, as for the rainfall triggering mechanism, Prof. Wang used ultra large and small physical models as well as the physical model on natural slope, to simulate the movement state of landslides under rainfall condition; as for the earthquake-landslides in loess area, his team adopted the fast shear test with carbon dioxide filling pores, which is a creative method.



On the afternoon of October 23, Prof. Cees Van Westen, from the Netherlands, gave a lecture titled “landslide hazard and risk assessment”,involving large landslides’ types, identification, monitoring and early warning, risk assessment, control and protection, and their impacts as well as the latest research progresses.



At 7:30 a.m., October 25, Prof. Niek Rengers arrived at classroom early to prepare today’s course. Today, Niek continued to teach these students how to publish academic papers, involving "purpose", "content", "subject", and "necessary factors for publishing". Prof.Nike, Prof. Cees, Prof. Mauri, Prof. Wasowski and Prof. Theo all elaborated the main points of paper review.


On that afternoon, Prof. Janusz Wasowski, from National Research Council of Italy, lectured on the application of MTI in the study of large landslides. Firstly, he described the background knowledge of InSAR.MTI. Then, he introduced the application of regional MTI in the early warning of slope disaster and the monitoring of large landslide. Based on the cases in Italy, Switzerland and Alps, he explained the analysis of large landslides and unstable slopes in local scale. After Janusz’s lecture, Vincenzo Del Gaudioas, from University of Bari, Italy, described the slope stability under the influence of earthquake, from following aspects: slope observation, landslide type, survey method, and analysis of seismic waves. Del Gaudioas is currently studying earthquakes and seismic hazards in southern Italy. All students attentively listened to these vivid introductions with sufficient cases.





In the class, teachers’ rigorous academic attitude and lively atmosphere deeply infected the students. They took notes carefully and communicated with teachers actively. So, for these students, it was not only a golden time to discuss with those famous experts face to face, but also a great opportunity to learn more about their majors.


On October 27, the closing ceremony of iRall School 2017 was held in Beichuan education center. First, representatives from each group summarized their fieldwork and shared what they have learned. Secondly, Prof. Niek summarized this iRall School and told them: “You should always maintain a passion for science, and strive for it. Maybe some of you will become the pioneers in this field. Try your best and never give up!”Finally, professors awarded certificates to students. In the evening, in order to celebrate the happy occasion,a grand party was held. All teachers and students sand and dances together. It was indeed a lively and happy night.




 Students are going to fly back to their countries, bring the research spirit of SKLGP to their own colleges. They are from different countries with different cultures and educations, but they got together thanks to iRALL School. During the short two-week course, they studied together, communicated with each other, and helped each other. A profound friendship has been built up here, and their horizon has been broaden as well. Thanks them for bringing us different scenery, and for making iRALL School more colorful!
