Table 1 RiskScape’s volcanic hazards, associated hazard exposure measurement unit (HEMU), and input formats for hazard module
From: Evaluating the impacts of volcanic eruptions using RiskScape
Volcanic hazard | HEMU | Input format |
|---|---|---|
Volcanic ashfall | Thickness (mm) | Raster |
Pyroclastic density current (PDC) | Damage  • Dynamic pressure (kPa)  • Presence/absence (default 50 kPa) Clean-up  • Deposit thickness (mm) | Raster (recommended) Presence/absence polygon |
Lava flow |  • Height (m)  • Presence/absence (default 5 m) | Raster (recommended) Presence/absence polygon |
Lahar | Damage  • Dynamic pressure (kPa)  • Inundation depth (m)  • Presence/absence (default 5 kPa and 2 m) Clean-up  • Deposit thickness (m)  • Presence/absence (default 2 m) | Raster (recommended) Presence/absence polygon |
Edifice |  • Height (m), positive for built edifice, negative for depression  • Presence/absence – cone (default +10 m)  • Presence/absence – caldera or maar (default −10 m) | Raster (recommended) Presence/absence polygon |
