The Latest: Helicopters sent to Hawaii as backup in eruption

HONOLULU -

(AP) - The Latest on the eruption of Kilauea volcano on Hawaii's Big Island (all times local):
  
12:25 p.m.
  
The U.S. Marine Corps is deploying two large transport helicopters to Hawaii's Big Island in case a volcanic eruption forces large numbers of people to evacuate.
  
Hawaii officials have said they may need to carry out a mass evacuation if lava crosses key highways and isolates communities in the mostly rural part of the island where the Kilauea volcano is erupting.
  
A blocked highway would cut people off from their only route to grocery stores, schools and hospitals.
  
The Marine Corps said Thursday that it's sent two CH-53E Super Stallion helicopters from a base near Honolulu to help. Each helicopter can carry 50 passengers.
  
Hawaii Army National Guard Brig. Gen. Kenneth Hara says the helicopters will allow an evacuation to be completed within a few hours.

Ash has continued to spew out from the summit of a Hawaii volcano amid intermittent explosions.
  
Scientists said Thursday that ash emissions from Kilauea volcano on Hawaii's Big Island reached 6,000 feet (1,828 meters) but quickly dispersed.
  
The ash is settling in small communities that are downwind. Trade winds are blowing the ash to the southwest.
  
Volcanic gas emissions at the summit remain high.
  
The high levels increase the potential for volcanic smog that's called "vog."
  
Emissions are also high at fissures that began opening up earlier this month in communities about 25 miles (40 kilometers) from the summit. Lava continues to erupt in two evacuated subdivisions.

Scientists in Hawaii have captured rare images of blue methane flames burning from cracks in the pavement as Kilauea volcano gushes lava in the background.
  
The photos and video offer a look at a new dimension in the volcano's weeks-long eruption.
  
The volcano produces methane when hot lava buries and burns plants and trees. The gas flows through the ground and up through existing cracks.
  
U.S. Geological Survey scientist Jim Kauahikaua (COW-ah-hee-COW-ah) told reporters it's just the second time he's ever seen blue flames during an eruption. He says it was dramatic and eerie.
  
The methane can seep through cracks several feet away from the lava.
  
Geological Survey scientist Wendy Stovall says the methane can cause explosions when it's ignited while trapped underground. Blasts can toss rocks several feet.
