About this Research Topic
In August 2009, the abnormal heavy rainfall during typhoon Morakot triggered a serious large-scale landslide at Hsiaolin village in Southern Taiwan, where a huge amount of mass was released and constructed a landslide dam. The subsequent dam breach caused debris flow which buried the village. More than 470 people were killed in this multimodal disaster (i.e. disaster continuously and simultaneously caused different modes and scales of sediment/mass movement). The post-event investigation indicates that the size of the Hsiaolin landslide is of the conventional slow-moving landslide (land creeping), but the high moving speed is as a shallow landslide. The mysterious complexity and severe destruction has received worldwide engineering attention and scientific interest, because such a multimodal disaster may take place all around the world. For example, the typhoon-triggered catastrophic landslides and debris flows (typhoon “Talas” 2011, Japan), the Oso-mudslide (2014, USA) and the landslides triggered by the earthquake in Hokkaido (2018, Japan) were also mournful.
In many countries, governments have paid attention and advocated an integrated approach to achieving a system of mitigation strategy for the catastrophic landslide and the subsequent multimodal disasters. However, there remain many challenges, to which this Research Topic is devoted: How to identify the locations susceptible to the landslides in an efficient way? Of which type is the landslide to take place? How to estimate the released volume? What are the predominant factors for failure initiation? When is the failure to take place? As well as the secured and endangered area when failure takes place.
Potential topics include, but are not limited to:
• Multiple surface monitoring technique, such as LiDAR, InSAR or GNSS, for identifying the landslide-prone area or the associated mobility;
• Advanced method/technique/modeling for identifying the landslide-prone area as well as estimating the released volume;
• Initiation or triggering mechanism of landslides;
• Large-scale landslide induced compound disaster as well as the 2nd disasters;
• Volcanic eruption induced landslides and the resulted compound disaster;
• Rainfall-induced landslides and the resulted compound disaster;
• Earthquake-induced landslides and the resulted compound disaster;
• Risk assessment, hazard management as well as disaster mitigation for landslide-induced compound Disaster;
• Landslide-related watershed-scale sediment budget Management as well as sediment transport hydraulics.
