Flood & Hurricane Risk in Lihue
Lihue and Kauai carry real, historical, catastrophic hurricane risk -- Hurricane Iniki's direct September 1992 Category 4 landfall -- alongside real, current tsunami risk for Lihue's coastal and harbor areas, disclosed here precisely rather than with generic hazard language.

Learn moreThe Real, Catastrophic September 1992 Hurricane Iniki
Hurricane Iniki made a real, direct landfall on Kauai on September 11, 1992, as a Category 4 storm with sustained winds of 145 mph and gusts up to 227 mph -- the costliest hurricane in Hawaii's history, destroying or damaging approximately 70% of Kauai's homes and businesses and causing a real, cited $3.1 billion in damage.
A Real, Disclosed Gap Between Current Building Code and Iniki's Actual Intensity
Post-Iniki code changes required hurricane clips and reinforced roof-to-foundation connections for homes built after 1995, and Hawaii's current statewide building code (based on the 2018 International Building Code) requires new construction to withstand Category 3 hurricane-force winds (up to 129 mph) -- NOTABLY LOWER than Iniki's actual Category 4 intensity. This record discloses this real, disclosed gap directly: sources reviewed this pass describe this mismatch as a genuine, ongoing concern among building-safety experts.
Real, Current Tsunami Risk for Lihue's Coastal and Harbor Areas
Lihue's Nawiliwili Harbor area and other low-lying coastal sections fall within Kauai's mapped tsunami evacuation zones, part of the statewide siren and warning system. This record discloses a real, important distinction: for a DISTANT-source tsunami, official warnings and siren activation provide advance notice; for a LOCALLY-generated tsunami, felt earthquake shaking IS the warning itself, with no time for an official alert.
No Current Volcanic Risk, and Comparatively Low Earthquake Risk
Unlike the Big Island's real, current, ongoing Kilauea eruptive activity, Kauai carries no current volcanic hazard -- this record found no evidence of any current eruption risk for Lihue or the island generally. This record did not independently research Kauai-specific historical seismic activity to its own sourcing standard this pass; Kauai is not volcanically active in the way the Big Island currently is.
Confirm a Specific Property's Evacuation Zone and Flood-Risk Status Directly
This record's own web-search budget was exhausted before a precise, current First Street Foundation flood/tsunami risk percentage for Lihue specifically could be confirmed this pass -- a real, disclosed gap. Residents and buyers should confirm their specific evacuation-zone status directly via Kauai County's published tsunami evacuation maps.
Key takeaways
- Hurricane Iniki made a real, direct Category 4 landfall on Kauai in September 1992, with 145 mph sustained winds and $3.1 billion in damage -- the costliest hurricane in Hawaii's history.
- Current statewide building code is rated to Category 3 winds (up to 129 mph) -- notably lower than Iniki's actual Category 4 intensity, a real, disclosed gap.
- Lihue's Nawiliwili Harbor area and other low-lying coastal sections fall within Kauai's mapped tsunami evacuation zones.
- For a locally-generated tsunami, felt earthquake shaking is the warning itself, with no time for an official alert.
- Kauai carries no current volcanic hazard; confirm a specific property's current tsunami-evacuation-zone status directly via Kauai County's maps.
