West Maui’s sirens are used primarily for tsunamis, MEMA Administrator Herman Andaya said as questions about warnings before the deadly wildfire are raised.
The White House points to the response on the ground: FEMA personnel have brought 50,000 meals, 75,000 liters of water, 5,000 cots and 10,000 blankets.
Residents who breathed contaminated air or searched the rubble without protective equipment may have been exposed to cancer-causing chemicals such as asbestos and lead.
Aina Kohler said everything that could go wrong did as firefighters desperately tried to stop the wind-whipped wildfire that burned into the Maui town.
A distant hurricane and severe drought conditions combined to create the kind of disaster that some scientists say show how climate change is a "threat multiplier."
While neither Maui nor HI-EMA activated warning sirens on Maui during the wildfire incident, the agency said, three other alert systems were implemented.
