DADO – Database di Danno Osservato (Database of observed damage), a platform developed by Eucentre, collects, organises and makes available data on the effects of earthquakes on Italian buildings. This information infrastructure is of great scientific and operational value, and was created to support research, prevention planning, and the management of seismic emergencies.

DADO is a digital archive that systematically documents damage to buildings following major Italian seismic events in recent decades. Data is collected through field surveys conducted by qualified technicians according to standardised protocols. This data includes information on:

  • type of construction and condition of the building.
  • level of damage suffered (from no damage to collapse);
  • geographical location (from individual buildings to municipal level);
  • Post-seismic conditions of practicability;
  • possible safety or demolition interventions.

The database is a strategic tool for reducing seismic risk. Its main objectives are:

  • provide a homogeneous and accessible database for analysing the behaviour of buildings during earthquakes;
  • support the modelling of the seismic vulnerability of buildings with real, verifiable empirical data;
  • guide post-earthquake prevention, strengthening and reconstruction policies by helping to identify widespread criticalities and intervention priorities;
  • encourage scientific research, the development of risk scenarios, and the calibration of forecasting models;
  • to document the effects of earthquakes over time in a transparent and traceable manner for the benefit of administrators, technicians, researchers, and civil protection personnel.

DADO is not just a data repository, but a constantly evolving platform which aims to enhance the wealth of information accumulated over years of field experience, making it a cornerstone of the national seismic resilience strategy. Knowledge of actual observed damage is a valuable resource for learning from the past and designing a safer future.
