Allen Bertram watched lava engulf his garden and then his house at 10 mph. He left with just the clothes on his back and his dog -- that later ran away -- and barricaded himself inside a neighbor's garage.
He survived off of canned food stored in their pantry.
Surrounded by lava, his moment of hope came when a helicopter flew overhead.
"Three garbage can lids, bright red, and marking paint and a red shirt as a flag. I was praying I was going to get rescued," Bertram said.
He added that the day he was rescued was the best day of his life. Now, he hopes he can find his dog.
