Kapaa, Hawaii

6 Land Tracts in Kauai County , Kauai Watershed

Kapaa, Hawaii, located in Kauai County, faces a relatively low overall natural disaster risk, with specific hazards including high tsunami and river flood risks. The area's proximity to the coastline increases vulnerability to tsunamis, as seen in historical events like the 1946 Aleutian Islands earthquake that generated a tsunami causing significant damage along the coast. Kapaa's river flood risk is evident from the Huleia River, which runs through the region and has a history of flooding during heavy rainfall events.

The geological features of Kapaa, such as the nearby Wailua River and Nounou Mountain, contribute to its hazard risk profile. Nounou Mountain, also known as the Sleeping Giant due to its shape, can pose a threat of landslides during periods of heavy rainfall or seismic activity. Additionally, the region's location within a seismically active zone increases the risk of earthquakes, although the risk level is relatively low. Kapaa's climate, characterized by high humidity, can further exacerbate the impact of natural disasters like hurricanes, which have the potential to cause widespread damage to the area's infrastructure and communities.

While Kapaa's natural disaster risk is relatively low overall, the presence of specific hazards like tsunamis, river floods, and the potential for landslides underscores the importance of preparedness and mitigation efforts in the region. By considering the area's unique geological features, climate factors, and historical events, stakeholders can work towards building resilience and reducing the potential impact of natural disasters on Kapaa and its residents.
