Print Updated tsunami hazard maps for Orange County will aid in planning evacuations should such a wave threaten local communities, the California Geological Survey said. The map is an update of the previous version, which was published in 2009. In Newport Beach, the tsunami hazard zone was increased slightly in the latest map to help facilitate evacuation responses. Hazard zones include the area between the Balboa Peninsula and Pacific Coast Highway, as well as Newport’s Back Bay. Meanwhile in Bolsa Chica and Huntington Beach, the tsunami hazard zone shrunk after new data showed that levees and ponds can help protect residents.
