Fig. 9

Main hazard map for tephra fallout in Martinique using the 41-year wind database and considering the 16 eruptive scenarios, with a the 5% probabilities to reach a deposit thickness of 1 cm (10.7 kgm⁻²), 10 cm (107 kgm⁻²), 20 cm (214 kgm⁻²), and 1 m (1,070 kgm⁻²). Note that the 1 mm threshold (1.07 kgm⁻²) is largely exceeded on land and is therefore not visible. In b, the same map is represented using five levels of damage intensity with red: complete destruction, pink: very high, dark orange: high, pale orange: intermediate, and yellow: low. These levels depend on tephra load thresholds presented in Table 1
