What is SIBER-RISK about?

Earthquakes represent 29% of the natural hazard occurrences in the world, cause 47% of human deaths and explain 35% of the global economic losses. In the case of Chile, earthquakes cost on average about 1% of our annual GDP, which is above 2.4 billion dollars per year. Extreme earthquakes severely damage the built environment and cause considerable social and economic harm, in many cases causing further disruptions. Damage to buildings, transportation systems, infrastructure, and critical facilities directly affect people and leave them vulnerable in the short and the long run. Although earthquake engineering has achieved significant advances in the last 50 years in terms of the response and risk of individual structures, current research requires to look at the more complex earthquake response of interdependent systems, and also extend their design objectives to foster resilience, thus including the adaptability of the system’s functioning prior, during, and following an event.

This research project attempts to contribute to the definition of a renewed resilience engineering aimed to expand our conventional snapshot risk design strategies into a comprehensive process that considers the complexity of large scale human-driven systems to mitigate the many aspects of risk.
