Methods, systems, and computer programs are presented for updating the data model of a structural damage predictor after an earthquake. One method includes an operation for identifying features for a structure and fragility functions for predicting structural damage to the structure, the fragility functions being stored in a database. The method further includes an operation for estimating a first damage to the structure after an earthquake utilizing a damage-estimation algorithm and the fragility functions for the structure. One or more of the fragility functions are changed based on the first damage to the structure when the first damage to the structure is above a predetermined damage threshold. The method further includes operations for accessing shaking data for a new earthquake, and for estimating a second damage to the structure after the new earthquake utilizing the damage-estimation algorithm and the fragility functions for the structure.
