A 4.6-magnitude aftershock centered at a depth of 10 km (6 miles) hit north of the Venezuelan capital Caracas early on Monday, according to the U.S. Geological Survey.
No damage was immediately reported from the aftershock, the president of the National Assembly, Jorge Rodriguez, said on social media.
Rescue efforts have been focusing particularly on La Guaira, the hardest-hit state of a country long mired in a deep political and economic crisis.
Wednesday's twin earthquakes have left close to 1,500 people confirmed dead and hundreds of collapsed buildings.
The international community has rallied to help Venezuela in the wake of the disaster. The country has received support from 24 countries, which have sent over 500 metric tons of supplies, more than 2,700 rescue and support personnel and about 86 canine teams, according to Venezuelan authorities.
