Many studies deal with the correlation between landslide velocity and damage degree of buildings or infrastructure. For shallow or moderate depth, slow landslides such as complex, slow flow or roto-translation type are well studied by InSAR or other ground-based instruments to retrieve a matrix correlation of velocity damage. However, few of them i...
