Rescuers have pulled survivors and bodies from the charred aftermath of the powerful eruption of Guatemala's Volcan de Fuego, or Volcano of Fire, with the death toll rose to 62 and set to increase.

The head of of Guatemala's National Forensic Sciences Institute reported the latest death toll, after the volcano erupted on Sunday, engulfing homes in three villages in the central American country and cutting off several communities from aid.

The disaster caught residents of remote mountain hamlets off guard, with little or no time to flee to safety and whole villages remain unaccounted for. Thirteen of the victims have so far been identified, with hundreds of others left injured..

As Guatemalan authorities dealt with rescue operations Israel said it had delivered food, blankets and medicine through its embassy.

Bodies were so thickly coated with ash that they looked like statues, and rescuers were forced to use sledgehammers to break through the roofs of houses buried in debris up to their rooflines to try to see if anyone was trapped inside.

“It is very difficult for us to identify them because some of the dead lost their features or their fingerprints” from the red-hot flows, Fanuel Garcia, director of the National Institute of Forensic Sciences said. “We are going to have to resort to other methods ... and if possible take DNA samples to identify them.”

Guatemalan authorities say they had been closely monitoring the Volcano of Fire, one of Central America's most active, after activity picked up around 6am Sunday.

The volcano has registered a number of minor eruptions over the years, and no evacuations were ordered as scientific experts reported the activity was decreasing.

Guatemala's disaster agency, Conred, issued a number of standard precautions, advising people to wear protective face masks, clean their rooftops of ash once the eruption was over and cover any food and water intended for human consumption. It also said to heed any recommendations from authorities. Guatemala City's international airport was closed due to the danger to planes.

Conred spokesman David de Leon said that around 2pm the volcano registered a new, more powerful explosion.

Soon, searing flows of lava, ash and rock mixed with water and debris were gushing down the volcano's flanks, blocking roads and burning homes.

“It travelled much faster. It arrived in communities right when the evacuation alerts were being sent out,” de Leon said.

Authorities scrambled to issue an evacuation order. Some communities emptied out safely. But in places like Los Lotes and the village of El Rodeo, about eight miles downslope from the crater, it was too late for many.
