Lāhainā Wildfire Death Toll Considerably Underestimated, New Research Finds
Table of Contents
New research unveils the true death toll of the deadly August 2023 wildfires which took place in Lāhainā, Maui, Hawaiʻi – and which temporarily made wildfire a leading cause of death in Maui. By comparing death rates over time, the scientists found that two-thirds more people died that August than would have been expected. To stop this happening again, the authors say, major policy changes are needed, ranging from removing flammable invasive vegetation to improving disaster preparedness.
“Wildfires can cause a measurable, population-wide increase in mortality, beyond what is captured in official fatality counts,” said Michelle Nakatsuka of the Grossman School of Medicine, co-first author of the article in Frontiers in Climate. “This suggests the true toll of the Lāhainā wildfire was even broader than previously understood.”
“It also points to the need for prevention strategies that go beyond reactive wildfire control,” added Nakatsuka. “As Native Hawaiians, the co-first authors are especially hopeful that wildfire mitigation strategies will center kānaka maoli perspectives, including the restoration of traditional agroecological systems.”
What Happened: The Lāhainā Wildfires and Initial Reports
On August 8, 2023, a series of wildfires erupted on the island of Maui, Hawaiʻi, fueled by strong winds from Hurricane Dora passing south of the islands. The town of Lāhainā suffered the most catastrophic damage, wiht entire neighborhoods reduced to ash. Initial reports indicated at least 115 confirmed fatalities, making it the deadliest U.S. wildfire in over a century (New York Times). Though, the new research suggests this number significantly underestimates the true impact of the disaster.
The New Research: Excess Death Rate Analysis
Researchers from the grossman School of Medicine at New York University and the University of Hawaiʻi at Mānoa utilized an “excess death rate” methodology to assess the full impact of the Lāhainā wildfire. this approach compares the number of deaths during the fire period (august 2023) to the expected number of deaths based on ancient data from August 2018 to July 2023 (Frontiers in Climate). The analysis accounted for demographic factors and excluded deaths directly attributed to COVID-19 to isolate the wildfire’s impact.
The study found that in August 2023, approximately 67% more people died on Maui than would have been statistically expected based on previous years. This suggests that the wildfire caused not only direct fatalities from burns and smoke inhalation but also indirect deaths due to factors like displacement, lack of access to medical care, and stress-related health complications.
