“…It has proven effective to use numerical models to examine seepage flow via embankments, dikes, and soil foundations. Numerical models may be able to assess the internal stability of soils with a specific GSD if an appropriate model for particle mobility within the soil matrix is used [23,33,37,91,92].…”

“…Studies aimed at understanding suffusion, the movement of soil through porous materials, have been conducted through numerical simulations (CFD) and experiments [24,[91][92][93]. The majority of these studies were macroscopic and based on the assumption that soil movement is a continuous process, which has yet to be proven through particle-level investigation.…”

“…This type of erosion is often associated with combined rainfall and seismic vibrations, which can cause the soil to become saturated and increase the water pressure within the soil [83]. The water pressure causes soil particles to be dislodged and carried away, leading to the formation of voids and cavities within the soil [90][91][92]. Over time, these voids and cavities can grow and cause the soil to become unstable, leading to the failure of soils and the structures on soil [18,67,73].…”

This paper employs the systematic literature review (SLR) methodology to investigate the combined effects of seismic vibrations and rainfall on soil suffusion, a process leading to soil instability. Earthquake activity can accelerate soil liquefaction, exacerbating suffusion, while heavy rainfall can increase soil weight, inducing instability. Consequently, the repercussions of seismic activity and rainfall on suffusion may induce further damage and instability to civil infrastructure. The review reveals that the compound impact of rainfall and seismic vibrations can precipitate severe damage and instability, primarily through two mechanisms. First, earthquakes can catalyze soil liquefaction, inciting soil movement and amplifying the suffusion process. Second, heavy rainfall can saturate the soil, augmenting its weight and rendering it unstable, thereby inducing suffusion. However, the review also reveals a significant gap in understanding and mitigating suffusion triggered by simultaneous rainfall and seismic activity. Current techniques for identifying and mitigating such suffusion are inadequate, highlighting the need for further research. This review posits that the interaction of rainfall and seismic vibrations as a catalyst for soil suffusion demands additional scrutiny. It provides a comprehensive understanding of suffusion and the impact of rainfall and seismic vibrations on suffusive soils, serving as a basis for future studies on this important issue.
