PAHOA, Hawaii >> The lava flow inching towards Pahoa caused two brush fires Thursday that continued to burn about 350 acres into the evening.

Both fires started from the active lava flow and were burning in a northeast direction, according to Hawaii County Civil Defense.

The fires were to the west of Highway 130, the area’s main throughway, about 0.6 to 0.9 miles from the Ainaloa subdivision.

According to a news release, the first breakout was about three-quarters of a mile upward of the Niaulani subdivision, and burned about 150 acres of brush.

The second breakout was about one mile from the Ainaloa subdivision and burned about 200 acres.

Two bulldozers were on the scene Thursday night to maintain the firebreaks, along with two choppers with water bucket drops.

A majority of the Ainaloa area lacks access to water, as much of the area runs off catchment water.

Hawaii County Assistant Fire Chief Gantry Andrade said that the first fire started close to 1 p.m. Thursday.

Fire officials were battling the first threat when a pilot noticed the other fire, he said, which came in around 2:30 p.m.

No evacuation had been ordered, but the Pahoa Community Center will open for residents if one is needed.

Andrade said the fires likely will be under control by Friday.

“We’re optimistic with nightfall approaching that the fires will slow down,” he said Thursday evening.

Meanwhile, a breakout of lava behind the stalled front of the flow from Kilauea Volcano had moved about 200 yards Thursday, igniting one of the brush fires.

Hawaii County Civil Defense said the breakout, now the most active part of the flow, is about 0.6 miles from Highway 130, and could head in the direction of the Pahoa police and fire stations.   

The progressing flow that may be overtaking the stalled tip started to emerge from the breakout on Jan. 9, volcano scientists said.

“It is the most active part of the flow at the flow tip and it very well could become the new active flow tip,” said Steve Brantley, acting scientist-in-charge with the Hawaiian Volcano Observatory. “Whether it is a few meters behind or ahead of the stalled tip doesn’t seem that important to draw attention to. It’s really the active part of the flow at this point.”

The breakout could head down a path of steepest descent that would take it to the police and fire stations near Highway 130, but Oliveira said it’s still too early to tell.

“One of the paths of steepest descent does take it in a direction of the fire and police station, but given the current activity we’ve seen and the trend that we’ve seen it,s somewhat premature to say that it is imminent or immediate,” he said. “But definitely there are paths of steepest descent that would take it in that direction.”
