MANOA, OAHU (HawaiiNewsNow) - Honolulu firefighters responded to a fire in the backyard of a Manoa home early Wednesday morning.
The emergency call came in around 5:45 a.m. Seven units staffed with 26 personnel responded to the home on Seaview Rise.
Honolulu fire officials say upon their arrival, they discovered flames coming from an old, drained pool-like space. HFD says it measured 15 feet by 15 feet, and was six feet deep.
A home's occupant reportedly was using the space as a workshop, HFD said.
Crews quickly worked to extinguish the flames. The fire was out just before 6:10 a.m.
Witnesses reported hearing three cannon-like explosions as flames shot 30 feet into the air.
An HFD spokesperson doesn't know the exact cause of the explosion, but speculates possible workshop-type items may have caused it.
No injuries were reported in the incident.
