    Even though the concept of resilience is becoming widely used in electric power systems, there is no consensus on how to systematically model or quantify it. This article begins by proposing a classification for different types of system risk analyses, associating them to the concept of power systems resilience. Thereafter, it describes and applies a resilience assessment and adaptation framework to the Northern Chilean electric power system in the context of its exposure to seismic events. This time-dependent analysis is evaluated throughout the disaster's impact and the network's operation and restoration timeframes with two indices: Energy not Supplied and Energy Index of Unreliability. Finally, the article compares a base case with three resilience adaptation strategies, namely, robust, redundant and responsive cases, in terms of their expected energy annual loss and the return period of different levels of network performance.
