Maui, HI – From August 8-9, 2023, Maui firefighters battled blazes in four locations across the island of Maui against hurricane-force winds upwards of 80 mph, forcing evacuations in Maui’s upcountry areas of Kula and Olinda, and in south Maui.

At the same time in the historic town of Lahaina, another wildfire raged as firefighters worked tirelessly to contain its spread. Fueled by drought conditions and hurricane force winds the fire quickly overwhelmed fire suppression efforts—engulfing the town, severing communications and power.

The true gravity of destruction and loss of life in the populous town of Lahaina didn’t become apparent until daylight during the early morning hours of August 9, 2023, when reports from flight crews and others on the ground began to emerge.

Within hours, preliminary scientific estimates of the impacts on population and infrastructure were developed by the Kihei-based Pacific Disaster Center (PDC) using its All-hazards-Impact Model (AIM) and advanced analytics. PDC’s estimates provided decision-makers with the first reliable understanding of the scale of fire exposure—now considered the deadliest wildfire in U.S. modern history. With estimated impacts in hand, and full activation of emergency forces already in place, the information helped expedite bringing together agencies from the state, public, private, and humanitarian sectors to support life-saving operations.
