以跨領域研究活躍及穩定增積岩楔區域中之地震誘發山崩(1/3)

Co-seismic landslides are dangerous secondary effects of earthquakes, but any comprehensive method to distinguish them from the rainfall-triggered ones is still missing. The Outer Western Carpathians in the Czech Republic is a tectonically similar region, where both types of triggers are possible, but less intensive and historical information does not allow to distinguish them. We examine present-day landslides in a very active setting with well-known and intensive rainfall and EQ triggers in Taiwan by using a unique combination of novel and well-established and integrated geological, morphometric, statistical, chronology and numerical methods, to validate that the seismic trigger leads to intense and rapid rock-mass disintegration and high mobility.In the past three years (i.e., 2022-2024), fruitful results and achievements have been accomplished in terms of academic research, bi-lateral exchange and cooperation deepening and promotion. In the aspect of academic research, two SCI papers have been published, and the third one is almost done and will be submitted soon. In addition, in order to conclude the research results from the bi-lateral research teams, an international conference was held in September 2024, which about 60 global researchers in the field of landslide attended. In the aspect of bi-lateral exchange, deep discussions and survey of landslide cases by bi-lateral research teams were done every year in both Taiwan and the Czech Republic. At the same time, visits to critical affiliations were also made in order to seek possibility of bi-lateral cooperations. Besides, self-developed 3-dimentional contactless and highly sensitive monitoring device on crustal deformation by the Czech research team have be installed in Taiwan to monitor surficial deformation caused by active geological structures. In the aspect of bi-lateral exchange and cooperation deepening and promotion, in addition to continuing and deepening existing b-lateral research, this project also promotes the cooperations between the National Museum of Natural Science, National Central University of Taiwan and the Czech Academy of Science. The content and objects of cooperation are confirmed in the form of MOU. In additional, the both academy of Taiwan and the Czech Republic have also a cooperation project on active structure research based on the bi-lateral experts and knowledge in order to deeper understand the scientific meanings.
