Risk estimates for exceedances of the information threshold for human population (2007–2011): spatial distribution (annual maps) and percentage of population exposed (column chart). Probability of exceedances: null (light blue), low (<30 %, green), medium (>40–60 %, yellow), and high (>60 %, red) (color figure online)
