Fire destroyed a vacant Kona house near Honaunau early this morning.

When firefighters arrived, the structure was in flames and had completely collapsed, the Hawaii County Fire Department reported. The overhead service line was down in the house and actively arcing, and brush around the house was burning, the department said.

Nine firefighters responded to the 12:39 a.m. alarm, and the first company arrived at 1:05 a.m. The fire was brought under control at 1:25 a.m. and extinguished at 3:30 a.m.

The single-family, single-story house at 87-2772 Hawaii Belt Road was unoccupied and vacant, and it is considered a total loss, acting Battalion Chief John Whitman said. The exterior of the old single-wall construction was covered with rock veneer, the fire department said.

Damage was estimated at $80,000. The cause remains under investigation.

Hawaiian Electric Light Co. arrived and disconnected the live service line.
