HONOLULU (AP) — The Maui Fire Department is expected to release a report Tuesday detailing how the agency responded to a series of wildfires that burned on the island during a windstorm last August — including one that killed 101 people in the historic town of Lahaina and became the deadliest U.S. wildfire in more than a century.

The release comes one day before the Hawaii Attorney General is expected to release the first phase of a separate comprehensive investigation about the events before, during and after the Aug. 8 fires.

The reports could help officials understand exactly what happened when the wind-whipped fire overtook the historic Maui town of Lahaina, destroying roughly 3,000 properties and causing more than $5.5 billion in estimated damage, according to state officials.

The Western Fire Chiefs Association produced the after-action report for the Maui Fire Department. After-action reports are frequently used by military organizations, emergency response agencies, government entities and even companies to help identify the strengths and weaknesses of the organization’s response to an emergency.
