TXT-tool 3.001-1.2: Physical Modelling of Earthquake-Induced Landslides
Earthquakes can be disastrous events causing loss of lives, damage to and destruction of infrastructure, economic losses, and can lead to other disasters such as tsunamis and fires. Moreover, they can serve as a triggering factor for hundreds to thousands of landslides in the region affecting by ground shaking. Asides from the ground shaking intensity resulting from an earthquake, several other factors including slope inclination, density of the slope material, antecedent and intensity and duration of post-earthquake rainfall can also influence the stability of a slope. As it is difficult to simulate field conditions and expected ground shaking, laboratory based models can assist in performing sensitivity analyses to understand the effect of various factors in triggering earthquake-induced landslides. In this tool, procedures for the development of simple laboratory models to perform such sensitivity analyses are described.
