    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : AnaCapri Mauro; [2022]
    Keywords : Social Vulnerability; Volcanic Hazards; Disaster Justice; Risk Governance; Temporal Analysis; Mauna Loa; Kīlauea; Social Sciences;

    Abstract : While there is a degree of homogeneity in the physical impact that volcanic hazards can cause, the experience of volcanic risk and the politics of exposure are far from equal. The purpose of this thesis is to expand on research citing population growth and property price dynamics as factors encouraging settlement in the Mauna Loa and Kīlauea lava hazard zones. READ MORE
