The June 24 double shocks, one of Latin America's worst quake disasters, toppled scores of buildings in the La Guaira coastal area north of Caracas and left thousands of people missing.
The International Organization for Migration said that up to 6.76 million people in Venezuela could be affected by the quakes, some 2 million of them in Caracas alone.
The earthquakes, among the strongest to strike in over a century, roiled the region, with buildings evacuated in cities and areas impacted as far as Brazil's Amazon, about 1,700 km from Caracas.
