The San Ramón Fault (SRF) is an active shallow crust fault located near to the city of Santiago, the most populated and economic center of Chile. Chilean Seismic Design Codes only account for interface events, neglecting the seismic hazard posed by the SRF, even when earthquakes with similar shallowness and magnitude have caused catastrophic losses over the world. The hazard posed by the SRF is computed and compared to interface and inslab events. Results suggest a high dependency on the approach used and the vibration period considered.

SRF is becoming a ‘new’ hazard for nearly 2 million people. Whilst researchers still disagree about the seismic hazard that the SRF represents for the city, the political need for action is challenging the traditionally successful way that seismic risk has been dealt with in Chile.

Touching upon issues of disaster risk reduction and urban development, the talk unveils the challenges of seismic risk governance in the context of urban and crustal faults, which span beyond engineering.
