- •
A framework for risk assessment of buildings due to landslides is presented.
- •
Earthquakes and rainfall are considered trigger factors through a GIS application.
- •
We present an approach that considers physical and probabilistic models.
- •
The model considers different values of Ah and conditions of soil saturation.
- •
The proposed model determines the amount of investment required to reduce the risk.
