Thursday morning the spokesperson of the Coordinating Agency for Disaster Reduction, David De Leon, announced the temporary suspension of the rescue operation due to bad weather conditions.
Subsoil temperatures hit up to 700 degrees during the height of the eruption, and now the search is well under way clearing the rubble of shattered homes, looking for bodies.
At least 99 people have been confirmed killed by the eruption, a number that is expected to rise further with almost 200 still missing.
The politicians are questioning whether or not the evacuation order was relayed to persons living in the surrounding area clearly, and with adequate warning, before the deadly eruption.
The White House said in a statement it was also dispatching aircraft to transport burn victims for treatment in Florida. The previous toll was 99.
Rainfall is complicating efforts to recover bodies in villages devastated by the eruption of Guatemala's Volcano of Fire, and some locals say many remains will never be removed. That's the length of time officials had said earlier that some victims might have survived. The agency said it made a decision to suspend the search now that 72 hours had passed.
The institute warned people Wednesday to be alert and avoid the area.
At a shelter in the Murray D. Lincoln school in the city of Escuintla, about 10 miles from the volcano's peak, Alfonso Castillo said he and his extended family of 30 had lived on a shared plot in Los Lotes where each family had its own home.
The U.S. government expressed its "deepest condolences" to the victims on Thursday and said it was sending emergency aid at Guatemala's request, including an unspecified amount of financial resources to help with food, water, and sanitation.
Fears of a new blowup of the 3,763-meter volcano have stalked rescue workers since Sunday's eruption buried entire villages on its southern flank. Guatemala is also home to 16.3 million people with more than 9% of the population living below the global poverty line.
