Hawaii top concern
Tsunami, lava-zone, water-source isolation
Hawaii's federated data is unusual: FEMA tsunami evacuation zones are state-managed alongside NFHL flood maps; Big Island lava-flow zones (USGS) overlay FEMA hazard layers. Each island operates independent water utilities, so EPA SDWIS PWSIDs do not aggregate across the state.
See Hawaii state page for the full state-level rollup across all 12 dimensions.
