We track household mobility spanning six years after the 2018 Central Sulawesi earthquake, tsunami, and liquefaction disaster. While most households return quickly and relocate short distances, there is substantial variation in the duration and severity of displacement. We further disaggregate displacement trajectories by household-level factors, including damage, income, tenure, and place attachment, offering insights into how displacement risks are unequally distributed.

This study uses data from the United States Household Pulse Survey to fit predictive models for displacement duration and return after disasters. Three predictive models are proposed, which range in complexity and predictive power. The leading contributors to different duration and return outcomes are also explored. These models can be integrated within disaster risk analyses, as illustrated through a hurricane scenario analysis for Atlantic City, NJ.

In the aftermath of an earthquake, the number of residents whose housing was destroyed is often used to approximate the number of people displaced (i.e., rendered homeless) after the event. This study benchmarks this conventional approach against officially reported impacts and data-driven estimates using mobile location data for three recent earthquakes in Haiti, Japan, and Nepal.

This review paper synthesizes the current literature on disaster-induced displacement, including key terminology and context, the determinants of household return decisions, existing model-based approaches, and opportunities for future research.
