Taiwan looks for missing after Super Typhoon Ragasa

Taiwan searched on Thursday for 33 people missing after a strong typhoon flooded a lake above a small town on its remote east coast, leading to a disaster as many victims were too elderly to follow evacuation guidance to go upstairs in their homes.

The deaths, their tally revised down to 14 from 17, followed heavy rains brought by the outer bands of Super Typhoon Ragasa to Hualien county, causing a barrier lake in the mountains to overflow and release a wall of water on the town of Guangfu.

Sub-tropical Taiwan normally has a well-honed drill for evacuations ahead of typhoons, especially in the mountainous and sparsely populated east coast, which limits casualties.

But the number of dead this time has prompted questions whether an order to head upstairs from the ground floor was appropriate, and what could have been done differently. "Beyond mourning the victims, we must investigate the causes of death, which predominantly occurred on the first floors," Premier Cho Jung-tai told a cabinet meeting on Thursday. "Clarifying these factors is essential for refining future evacuation protocols."

ELDERLY POPULATION

Many rural parts of Taiwan, especially in the east, have large elderly populations as the young move to cities to seek better job opportunities.

The elderly with disabilities made up the majority of the dead, many found on the first floors of homes, Hualien official Lin Jung-lu told Reuters. "They had difficulty walking," he added.

Chang Chih-hsiung, a youth representative of the Fata'an tribe of the Amis indigenous group which calls Hualien home, said the digital gap and ineffective communication were among the reasons why some older people did not evacuate. "Some of them are not familiar with using cellphones," he told Reuters. "The village chief had held briefings, but people didn't think it was that serious until it happened."

Another problem was the sheer scale of flooding and the difficulty of predicting where it could hit. Parts of the village were entirely evacuated with people moved to shelters, but that area escaped the flood, Chang added, while other spots where many opted to move to higher floors, however, were hit far worse than expected.

CUT BRIDGE

Wang Tse-an, head of the village of Dama in the Guangfu region, said a mandatory evacuation order meant the hamlet suffered no deaths.

"Dama was the first to be hit, but the damage is the smallest," he said. "That's because we designated houses for mandatory evacuation. But when the flood came to other villages people there thought they could just do 'vertical evacuation'. They did not expect the flood to reach that high."

While Guangfu's train station has resumed services, the main highway has been cut off after flood waters swept away a bridge. Drone imagery from Reuters showed only the bridge supports left in the river bed after the road links snapped at both ends. In other images, homes were marooned in mud that blocked entrances.

Wang said many meetings had been held since the lake was discovered in July, with several briefings delivered to villagers about the coming dangers and evacuation plans, some in the Amis language, as not all residents spoke Chinese.

The rain has stopped, but the government maintains warnings on the barrier dam in a remote mountain area behind Guangfu.

The tricky issues of how to tackle the lake, though much smaller than before, and prevent another disaster remain.

Agriculture Minister Chen Junne-jih said using explosives to blow up the bank holding back the lake was too dangerous as it could set off more landslides. "While the red warning is still in place please do not go near to the river," he told reporters in Taipei.
