A raging three-alarm blaze that damaged or destroyed six structures Wednesday was intentionally set, fire investigators said.
No injuries were reported in the fire that started about 7:40 p.m. Wednesday.
Four of the six structures are said to be heavily damaged or destroyed, while one fully collapsed.
Damage from the blaze is estimated at $1 million.
As many as 55 firefighters and 15 fire companies helped put out the fire, which started at a two-story single-family home at Hauoli and Waiola streets.
When they arrived, the building was already fully engulfed in smoke and flames.
There were reports that two people were home when the fire started. Fire investigators worked throughout the night, searching through the rubble to try to confirm if anyone was inside.
Neighbors say they heard explosions accompanying the flames. Fire crews were also concerned with active power lines falling and sparking.
"The scariest part was that the fire was reaching so high it melted the cables that was overhanging," witness Taiki Hayakawa said. "They were snapping, making quite a loud noise, like bangs. The cables were falling so officers told us to move out of the way."
