There are 28 people dead and more than 100 still missing and suggestions the building may have been poorly built.
Rescue teams in Taiwan still hope to find more survivors in the collapsed 17-storey apartment tower in Tainan.
A 6.4-magnitude quake caused the lower floors of the building to fall on top of each other and then the whole structure toppled.
This woman describes the moment that quake struck.
"Everything was shaking violently, then it come a big crash. When we rushed out, we saw the building had collpased."
Officials say more than 120 people are believed to be still trapped in the rubble.
Cheng Chi-Feng, from the Tainan City Government Rescue Team, says they still hope they'll find survivors.
"We used a life detector to look for survivors, and in the end we did not detect any signs of life. If we find any signs of life, we will be digging to find them."
Those found alive include a 20 year-old man and another man in his 20s, who was able to walk out of the wreckage, supported by rescuers.
Both were sent to hospital.
Tainan Mayor William La says they've had to ask for assistance from across the country.
"At the moment, the rescue force consists of special search teams from various counties and cities across Taiwan who have come to provide assistance."
Taiwan is located in an earthquake-prone area and most buildings are built to withstand the majority of tremors.
The collapse of this building has raised questions about the quality of materials and workmanship used in its construction in the 1990s.
The buildings around it were able to withstand the 6.4 quake.
A Tainan government official said television footage of its ruins suggest there may have been structural problems related to poor-quality reinforced steel and cement.
However, city officials have said it is too early to say for certain if poor construction was a factor in the collapse.
Building authorities say the building had 96 apartments and 256 registered residents, though more people were inside when it collapsed.
