People who live in Lahaina on the Hawaiian island of Maui have been allowed back to their homes - to see if they're still standing.
At least 80 people have died, but hundreds are missing and searches continue - in what has become Hawaii's deadliest natural disaster since 1960, when a tsunami killed 61.
Wildfires have turned many properties into burnt out shells after flames virtually wiped out the historic town.
They were fuelled by a dry summer and strong winds-from-a-passing-hurricane, and took Maui residents by surprise.
But there are questions about why Hawaii's emergency sirens failed to sound a warning.
Emergency responder Dr Reza Danesh has been telling NBC about the scale of the disaster:
"It was devastating. It felt like a war zone. And it was still fresh. I could see trees burning, I could feel the smoke. I could feel the heat. And it was basically like the another pandemic to explain it. It was a ghost town, very apocalyptic".
