Gridded volcano mortality risk estimates classify global hazard into deciles based on historical loss data and population exposure. The 2.5-minute resolution dataset integrates hazard frequency, subnational population estimates, and mortality records from EM-DAT. It was produced in 2000 by Columbia University's CHRR and CIESIN in collaboration with The World Bank.
Use Cases
- Mapping decile classes of mortality risk to identify global hotspots for volcanic disasters.
- Analyzing the correlation between gridded hazard frequency data and historical mortality loss records.
- Estimating potential mortality numbers by combining hazard data with year 2000 subnational population estimates.
- Comparing volcano mortality risk deciles across regions for international disaster preparedness funding allocation.
Strengths
- Global coverage at a 2.5-minute grid resolution.
- Integrates three distinct data sources: hazard frequency, population estimates, and historical mortality records.
- Risk classification into 10 deciles provides a standardized comparative scale.
Limitations
- Data is based on year 2000 population estimates, not reflecting current demographics.
- Historical mortality data from EM-DAT may have reporting gaps for certain regions.
- Mortality estimates are derived models, not direct observations.
