Rescue teams from Ecuador and the United States halted operations early on Tuesday in Macuto, a town in La Guaira state - the area hardest hit by the June 24 earthquakes - after more than 40 hours of work, when they stopped receiving responses from a mother and her three children trapped beneath a nine-storey building.
"In the end, we believe the days have already passed and that what we will find now is death," said Major Jorge Montanero, leader of the EQ11 team from Guayaquil, located on Ecuador's Pacific coast.
"Unfortunately, things haven't developed favourably," he said as he stood amid rubble after cutting through four concrete slabs of the building in an effort to locate the four trapped victims.
About 59,000 buildings were damaged or destroyed by the twin earthquakes - which hit just seconds apart with magnitudes of 7.2 and 7.5 on June 24 -according to an experimental NASA estimate based on satellite imagery.
The widespread devastation can be seen from space.
Not all collapsed buildings have had professional rescue teams on site, with relatives and neighbours working to remove debris to pull out survivors or bodies, according to survivors and residents from various areas.
"There is no doubt we are facing a figure higher than what has already been reported. I can offer an estimate: we are procuring - and this has been agreed with local authorities - 10,000 body bags," Gianluca Rampolla, the United Nations' resident co-ordinator in Venezuela, said on Monday from his office in Venezuela's capital Caracas.
The government of acting President Delcy Rodriguez says at least 1750 people have died and thousands have been injured as a result of the earthquakes.
About 16,000 people were left homeless.
A website promoted by the country's political opposition puts the number of people still missing at about 43,000.
