An elderly couple was injured early this morning in a Kurtistown structure fire, Hawaii County fire officials said. 

Firefighters arrived at the home on Opeapea Street in the Hawaiian Acres subdivision around 5:30 a.m. to find live power lines down and a 900-square-foot structure completely ablaze. 

The man and woman who occupied the home were able to escape but had to be taken to a nearby hospital, officials said. 

Crews had the fire under control within 10 minutes and extinguished it around 7 a.m., according to officials.

The walls and floor of the unfinished home were wood, and the roof was metal. Damage was estimated at $105,000.

Officials said the cause of the blaze is still being investigated.
