Technology Enhances Early Warning for Landslides - Smart Landslide Information System – HKJCDPRI Research Grant 2016 (Final Report)

The research entitled “Smart Landslide Information System” led by the research team of the Department of Civil and Engineering of the Hong Kong University of Science and Technology, in collaboration with the Hong Kong Jockey Club Disaster Preparedness and Response Institute was completed in November 2017.

 

A hilly terrain and seasonal torrential rainfalls present Hong Kong with the ideal conditions for landslides. With the advent of climate change, the number, scale, spatial extent, and frequency of landslides are expected to be unprecedented. With a comprehensive and world-leading slope safety system in place, there are always opportunities to examine ways to embrace technology and try to further enhance the management of landslide disasters to cope with the dynamic climate conditions that the world is facing.

 

The Landslide Information System (LIS) is a data base powered by a mobile phone application. The LIS leverages crowdsourcing from mobile phones to enhance the scale and resolution of landslide information, such as GPS coordinates and photos. It is also one of the first mobile applications for the management of landslide disasters designed for the general public and to demonstrate the collaborative efforts in sharing of risk information from the communities.

 

The app utilizes GPS technology and an existing susceptibility model to track and warn the general public of high-risk areas. By coupling data from crowdsourcing and data from instrumentation, landslide mitigation and management can be taken to a whole new level.

 

In the next phase of the research, sensors will be developed and installed in landslide-resisting barriers to warn downstream facilities of potential landslides danger. The research team also realized that the technology can also be used to enhance the resilience of Hong Kong against a wide-range of disasters, such as floods, collapsed trees, crime or medical-outbreaks.

 

The research team will continue to disseminate the research outcomes, and are currently working with practitioners to examine potential channels for targeting some of the research findings towards the general public.
