Brad Guay, 22, was visiting Guatemala from Hoboken, New Jersey, on July 9, when he woke up to "the ground under my tent shaking and a series of low rumbles, punctuated by occasional louder explosions."

Guay was camping on another volcano called Acatenango, which is about a mile and a half away, when the Volcán de Fuego began erupting. He captured a photo of the eruption, showing the volcano piercing the cloudy sky with lava.

"The lava was shooting up to 300 meters (about 980 feet) into the air, and was spilling down the side of the volcano," Guay said. "The volcano would also throw hot boulders that were probably about the size of a car through the air, which was pretty incredible to see."

It was an amazing sight, Guay said. "I assumed it might show a little bit of lava for a few minutes if we we're lucky and that would be that. (I) totally didn't expect it to be exploding for hours on end."

Fernando de Dios, a 24-year-old from Guatemala, said he posted a video of the volcano after he and a group of friends hiked it on Sunday.

Coordinadora Nacional para la Reducción de Desastres, the government agency tasked with warning residents and visitors to potential environmental disasters, discourages people from getting to close to an active volcano due to falling debris and the instability of the activity.

They were about 650 meters (about 2,130 feet) from the active cone, de Dios said, when he captured a video of black ash billowing toward the sky.
