Every year, thousands of people around the world who face unequal access to political and social power and resources lose their lives and/or livelihoods in natural hazard events. As a result, the reduction of vulnerability has become a central concern of humanitarian actors. This paper analyses the impact of humanitarian assistance on vulnerabilities in Nepal following the Gorkha earthquake on 25 April 2015. The causes and manifestations of vulnerability before and after the disaster are determined through the application of the Pressure and Release model and the adoption of a mixed‐methods research approach. The findings of the study reveal that 20 months after the earthquake, humanitarian assistance had not had any long‐term positive influences on the root causes of the phenomenon, and that vulnerabilities at the micro level could be resolved in part. To diminish the extent of disasters in the future, however, the fundamental reasons for the vulnerability have to be addressed better.
