When the devastating wildfire tore through the town of Lahaina in Maui, the state-of-the-art emergency sirens failed to sound the alarm. This decision has been a source of confusion and bewilderment, considering that sirens are designed to warn and protect people. The official responsible for this choice, Herman Andaya, resigned due to health reasons. Nevertheless, officials have defended their decision, highlighting the complexities surrounding the use of sirens during a wildfire evacuation.
Tom Cova, a wildfire-evacuation expert, explained that sirens have both advantages and disadvantages. While they can alert and mobilize people, they do not provide crucial information such as evacuation routes or road closures. In the case of the Maui fires where limited information was available and key routes were blocked, the use of sirens may have led to traffic congestion and confusion.
Officials also expressed concern that people may mistake the sirens for a tsunami warning and flee towards the fire. Erica Kuligowski, a professor studying disaster-warning sirens, emphasized the importance of educating the local population about the meaning of sirens and providing additional messaging through emergency texts. However, with a significant tourist population, it would be challenging to train every visitor on how to respond to a siren.
The absence of sirens was not the only issue during the wildfire evacuation. Many survivors reported not receiving any form of notification, and key escape routes were reportedly blocked. Questions arose about the nine-hour gap between the fire’s ignition and its spread, as well as the lack of partial evacuations despite the strong winds. These questions highlight the imperfect nature of disaster response and the need for effective preparation and experience in handling such situations.
Experts acknowledged that the Maui community faced an unprecedented and overwhelming fire, even for a place accustomed to wildfires. Comparisons were drawn to the Camp Fire in Paradise, California, which had a well-prepared evacuation plan but still faced significant challenges. Every community, especially those at high risk of fire, should consider developing a comprehensive wildfire-evacuation plan. Resources like the wildfire risk mapping tool provided by the U.S. Forest Service and USDA can aid in identifying areas that require more focused attention.
Elizabeth Pickett, a co-executive director of the Hawaii Wildfire Management Organization, emphasized the importance of acknowledging the reality and speed of wildfire incidents. Planning for evacuation should include effective communication strategies, multiple evacuation routes, and designated refuge areas. Attention should also be given to the most vulnerable populations, such as those without transportation, children, older adults, non-English speakers, individuals with disabilities, and tourists.
In recent times, evacuation planning has benefited from advanced simulation programs that allow for testing and evaluating different scenarios. These simulations consider various factors like vegetation, housing types, traffic layouts, and demographics, enabling emergency planners to optimize evacuation plans and ensure the safety of residents.
While the exact number and details of the casualties in Maui are still unknown, stories of tragic loss are beginning to emerge. It is a stark reminder of the importance of thorough emergency preparedness and the need for communities to be proactive in implementing evacuation plans tailored to their unique circumstances.
