Victims of Taiwan's earthquake breathed a sigh of relief yesterday when they were told Typhoon Dan would miss the island, but were warned by officials to remain vigilant. Officials said bad weather caused by the typhoon could make life more difficult for the tens of thousands of homeless and threatened hi-tech industries. Dan raged through Luzon, in the Philippines, yesterday morning, its outer bands taking heavy rainfalls to Taiwan. Rain was expected to continue today and for the next few days. 'Although the typhoon will not directly hit us, it will bring heavy rainfall to southern and eastern Taiwan,' said Central Weather Bureau director Chen Lai-fa. 'Mountainous areas in these regions will be badly affected. The rainfall will cause landslides and rock falls which will pose a serious threat to many towns and roads.' Eastern cities, such as Ilan and Hualien, would have heavy downpours and the quake-hit counties of Nantou and Taichung would also experience bad weather. Taichung government chief Liao Yung-lai said an emergency headquarters had been set up to help thousands of people made homeless by the September 21 quake, which killed 2,294 people. Mr Liao said: 'We have opened up schools and other public buildings for the homeless to stay. We urge people who are still living in tents to go back to their houses.' Most earthquake victims were too scared to stay indoors because of frequent aftershocks, said Mr Liao. 'Actually, many buildings are not in danger of collapse, people are just scared by the earthquake and fear more aftershocks,' he said. Taipower, the island's state-run electricity monopoly, said the bad weather could trigger another round of power blackouts. Director Lee Chuan-lai said: 'Many high-voltage transmission towers are newly built. They don't have earth lines, therefore could be vulnerable when lightning strikes.' Officials of Taiwan's main computer chip production base, Hsinchu Industrial Park, said manufacturers faced another difficult test if the power supply was disrupted again by the bad weather. Chow San-yi, vice-director of the hi-tech centre, said it would cost as much as NT$500 million (HK$120 million) a day if there was another power failure. 'If the power cuts happen again, many production lines would have to stop and some finished computer chips would be wasted,' said Mr Chow.
