RISK OF BUILDING DAMAGE BY MODELING INTERFEROMETRIC TIME SERIES

Predicting building damages due to ground movements caused by subsidence phenomena is a great challenge in the field of Risk Management, moreover in the process of Disaster Risk Reduction. This damage assessment integrates measurements obtained from satellite SAR observations with an intermediate semi-empirical model, which schematizes buildings as equivalent laminated beams. The monitoring and modelling stages have been embedded to investigate densely urban areas. Two test sites have been examined: the Southern part of the city of Rome (Italy) and a recently constructed building in Astana (Kazakhstan). Furthermore, the importance of each of the parameters involved in the semi-empirical method for modelling building deformation has been evaluated to understand the applicability of the modelling in different urban contexts, with different knowledge of the urban pattern.
