  The power system is among the most important critical infrastructures in
urban cities and is getting increasingly essential in supporting people s daily
activities. However, it is also susceptible to most natural disasters such as
tsunamis, floods, or earthquakes. Electricity vulnerability, therefore, forms a
crucial basis for community resilience. This paper aims to present an
assessment framework of spatial-temporal electricity vulnerability to support
the building of community resilience against power outages. The framework
includes vulnerability indexes in terms of occupant demographics, occupant
activity patterns, and urban building characteristics. To integrate factors in
these aspects, we also proposed a process as activity
simulation-mapping-evaluation-visualization to apply the framework and
visualize results. This framework can help planners make an effective
first-time response by identifying the most vulnerable areas when a massive
power outage happens during natural disasters. It can also be integrated into
community resilience analysis models and potentially contributes to effective
disaster risk management
