"When a storm is coming up you cannot hear the thunder. When it's over top of it you can. In this house that roar was completely in every room. It was extremely loud."
UPDATED 6:30 PM -- The town of Knifley has a population of about 500 people. Residents say it's usually quiet. That was until Thursday, when they got the wake up call of a lifetime.
"It looked like a sunrise. It was very visible from Green County. Which is about 20 miles," said Green County Emergency Management Director, Bill Matney.
The explosion happened around 1 a.m. It was caused by a pipeline leak that ignited, leaving 2 homes demolished, 2 people being treated and released from the hospital, and a crater that reached 60 feet deep and 50 feet wide.
"There were two agricultural barns and forest fires going on in the hill sides. There were four to six automobiles on fire," added Adair County Emergency Management Director, Greg Thomas.
Those who live near the center of the blast said the initial sound and flash had them fearing for their lives.
"When a storm is coming up you cannot hear the thunder. When it's over top of it you can. In this house that roar was completely in every room. It was extremely loud," said Tammy Burton, who witnessed the fire.
Adding to that noise, Burton said what sounded like a hailstorm banged on her roof for minutes after the blast, but it wasn't precipitation. It was falling rock that had shot from underground at the site one mile away.
After a few hours, all of the fires were put out and the area was deemed stable. The Columbia Pipeline Group, who owns the line that burst, said they're still investigating what may have caused the entire event.
Shortly after the blast, 20 homes were evacuated. All of those people were allowed to return to their houses just a few hours later.
