Ewa-Beach, Hawaii

22 Land Tracts in Honolulu County , Oahu Watershed

Ewa-Beach, Hawaii, has a relatively moderate overall natural disaster and climate risk assessment, with very high tsunamis and relatively high river flooding risks. The area is prone to tropical storms and hurricanes, with a history of destructive events such as Hurricane Iniki in 1992. The high humidity levels in the region contribute to the potential for heavy rainfall and flooding, particularly along the coastlines and low-lying areas.

Located in Honolulu County, Ewa-Beach is situated near the Oahu hydrologic unit and subregion, which further increases the risk of flooding and water-related hazards. The region is also close to fault lines, such as the North American-Pacific plate boundary, which can lead to seismic activity and earthquakes. With its proximity to the Pacific Ocean, Ewa-Beach faces the threat of tsunamis, as seen in past events like the 1960 Chilean tsunami that affected Hawaii's coastlines. These geological features and historical events highlight the potential for natural disasters in the area.

While certain risk factors like wildfires and volcanic activity are not applicable to Ewa-Beach, the combination of climate factors, geographic location, and geological features poses a significant hazard risk to the population. It is crucial for residents and local authorities to be prepared for potential disasters and have effective emergency response plans in place to mitigate the impact of natural hazards in the region.
