Welcome to our Research Group

The Flowslide and Liquefaction Research Group investigates the junction of two significant geotechnical phenomena: flowslides and soil liquefaction. This group would look into how liquefaction can cause flowslides, especially on natural slopes or man-made earth structures. They would focus on the severe long-distance flowslide that happened during the Mw 7.5 Sulawesi Earthquake in Indonesia in 2018 as an example.

Welcome to our Research Group

At this Flowslide and Liquefaction research group, we are dedicated to advancing the field of geotechnical engineering through groundbreaking research on soil liquefaction, flow slides, and earthquake-induced ground motions. With a special focus on Indonesia’s earthquake-prone areas, we aim to understand the complexities of soil-structure interaction and mitigate the risks posed by seismic events in vulnerable regions. Our research explores innovative solutions to earthquake risk management, soil stability, and dynamic soil behavior, specifically tailored to the unique challenges faced by Indonesian communities. Join us as we work to contribute to a safer, more resilient future by enhancing geotechnical risk assessment and advancing the science of seismic hazard mitigation.

Research Sub-Theme

Mechanisms of Long-Distance Flowslide Induced Liquefaction

Exploring the mechanisms through which liquefaction triggers flow slides across diverse soil types and seismic characteristics..

Development of Hybrid FEM - MPM Modeling

Developing advanced computational models using a coupled Finite Element Method (FEM) and Material Point Method (MPM) to simulate the onset and progression of flow slides, capturing both the initial triggering of liquefaction and the complex, large-scale deformations in various soil types and seismic environments.

Field Geophysical Surveys

Conducting comprehensive field and geophysical surveys to investigate flowslide-induced liquefaction, utilizing advanced techniques such as seismic refraction, ground-penetrating radar (GPR), and resistivity imaging to assess subsurface conditions, soil behavior, and the triggers of soil instability. These surveys help us understand the relationship between seismic activity, soil liquefaction, and flow slide mechanics, providing crucial data for improving geotechnical hazard assessment and earthquake risk mitigation in vulnerable regions.

Risk Assessment and Mapping of Flowslide Liquefactio Areas

Conducting comprehensive risk assessment and mapping of liquefaction potential in vulnerable regions, using advanced geotechnical models and seismic data to identify high-risk areas. This process helps pinpoint zones with the highest likelihood of soil liquefaction, enabling more effective earthquake risk mitigation, land-use planning, and disaster preparedness strategies.

Development of Mitigation Techniques

Advancing the development of innovative mitigation techniques to prevent and reduce liquefaction hazards, including the use of soil stabilization, deep foundations, and ground improvement technologies. These techniques aim to enhance seismic resilience, protect infrastructure, and improve disaster risk reduction strategies in earthquake-prone areas, ensuring safer and more sustainable communities.
