Modeling the dynamics of stress propagation in disaster situations is crucial for effective emer gency response planning and risk management.In this paper, we present a macroscopic first-order compartmental advection-diffusion-reaction
model that describes how populations in two separate interconnected zones ?1 and ?2, via
their human behaviors (compartments) that represent the stressed and non-stressed populations
respectively, interact via stress contagion within each zone and migration between these two
zones, spatial propagation is also considered.
