A powerful earthquake of 6.4 magnitude struck the city of Tainan in the south of Taiwan at around 4 a.m. (2000 GMT) on Saturday killing at least eight people, most in a 17-storey apartment building that collapsed, with five people still missing in the ruins, Reuters reports.
As rescuers searched for survivors, questions were raised about the construction of the Wei-guan Golden Dragon Building in the southern city of Tainan, with its floors that pancaked down on each other.
Authorities said there were 96 apartment units and 256 people living in the collapsed building. In the evening, five of them were still missing.
Rescuers found 250 survivors from the ruins and later inserted huge supports under slabs of leaning concrete to buttress the ruins as they searched for more.
The fire department said 115 people had been taken to hospital from around Tainan.
Buildings in nine other locations in the city of 2 million people had collapsed and five were left tilting at alarming angles, a government emergency center said.
The center of quake was located 43 km (27 miles) southeast of Tainan, at a depth of 23 km (14 miles), according to the U.S. Geological Survey.
