Journalists in the impact areas reported scenes of chaos, with ambulances and rescue crews rushing to attend crumbled buildings.
Local resident Muna al-Omar told the Reuters news agency she feared the earth was “going to split open under my feet”.
She was one of many people housed in temporary tent accommodation at a park in Antakya’s city centre when the earthquakes hit.
Residents of other hard-hit areas struck again on Monday had complained of a lacklustre government response to their suffering following February 6.
The death toll from the quakes two weeks ago rose to 41,156 in Turkey, and it was expected to climb further.
AFAD said 385,000 apartments are known to have been destroyed or seriously damaged, and many people are still missing.
At least 47,000 people are thought to have died, with the numbers expected to rise further.
The Turkish president, Recep Tayyip Erdoğan, said construction work on nearly 200,000 apartments in 11 earthquake-hit provinces of Turkey would begin next month.
Hours earlier, the US Secretary of State, Antony Blinken, said on a visit to Turkey that Washington would help “for as long as it takes” as rescue operations and aftershocks were winding down, and focus turned to towards urgent shelter and reconstruction work.
“It’s hard to put into words,” Blinken said, trying to describe what he saw. “Countless buildings, communities, streets, damaged or fully destroyed.”
Syrian officials say 1,414 people were killed in areas under the control of Assad’s government, amid concerns the true figure was likely to be far higher before the second earthquake struck.
Britons have donated almost £100million in just 12 days for victims of the devastating earthquakes in Turkey and Syria.
Money raised has been sent directly to those affected, with the process overseen by experts on the ground with intimate knowledge of where it is needed most.
The Disasters Emergency Committee appeal has raised a staggering £91million, with the landmark £100million figure set to be topped in the next couple of days.
Speaking exclusively to the Daily Express, Saleh Saeed, the DEC’s chief executive, said the response was “truly humbling”.
He added: “When it comes to generosity, the British public excels – something we are all proud of. When it counts, you act.
“So far, the DEC Turkey-Syria Earthquake Appeal has raised an incredible £91million in just 11 days. We are extremely grateful that even in these times of hardship for many in the UK, you have dug deep and shared your hard-earned cash.”
