New Multi-temporal Global Population Grids – Application to Volcanism

Better and finer global analyses of human exposure and risk of natural disasters require improved geoinformation on population distribution and densities, in particular concerning temporal and spatial resolution and capacity for change assessment. This paper presents the development of new multi-temporal global population grids and illustrates their value in the context of risk analysis by estimating the worldwide distribution of population in relation to recent volcanism. Results indicate that almost 6% of the world’s 2015 population lived within 100 km of a volcano with at least one significant eruption, and 11% within 100 km of a Holocene volcano, with human concentrations increasing since 1990 above the global population change rate. The novel population grids constitute the new state-of-the-art in terms of global geospatial population data, with the potential to advance modeling and analyses at all stages of the emergency management cycle.
