Seismic Resilience of Infrastructure Systems during the 2015 Nepal Earthquake Event
Rare destructive earthquakes cause tremendous suffering and huge losses. But they also create a living laboratory. In the past, the engineering profession has learned from earthquakes and made buildings and bridges more robust. Today we know that survival of the built inventory alone does not guarantee that the affected community will recover from an earthquake. Community resilience is the ability of the community to bounce back after a catastrophe. Valid models are needed to engineer better community resilience. The 2015 Gorkha (Nepal) earthquake is an opportunity to study the loss absorption and the recovery processes associated with civil infrastructure in Kathmandu after this event. One objective of this project is to collect and analyse the data about the performance of civil infrastructure systems and to calibrate and validate a compositional resilience model. This model can be used to plan the remaining recovery in Kathmandu and to prepare for future earthquakes in this region by using the model to design more resilient communities and, more important, to transfer the knowledge about resilience and rebuilding to the engineers, emergency and recovery managers and public policy makers. The partnership between ETH Zurich and IIT Bombay brings together two strong civil engineering schools whose students are capable of taking the reconnaissance, data collection, analysis, modelling and dissemination tasks, not only in Nepal, but also in India, Bhutan, Bangladesh and China, countries where the April 25, 2015 earthquake also caused casualties, injuries, damage and losses.
