CHUNCHEON, South Korea (Reuters) - Torrential rain battered the South Korean capital Seoul and surrounding regions Wednesday, causing dozens of landslides and flash floods that killed at least 32 people, the emergency services said. In the worst single accident, a landslide crashed into a mountain resort at Chuncheon, east of Seoul, destroying three small hotels and killing at least 13 people."Then I heard someone shouting 'help me'. So I went out to see, and I saw a landslide had swept all over the area," she said. Another landslide on the outskirts of Seoul buried dozens of houses and killed at least 10 residents, local media reported, adding that one villager was missing. A tributary of the Han River running through Gonjiam, about 50 km (30 miles) southeast of Seoul, had overflowed and killed five residents, Yonhap news agency reported. Wild weather has battered the central region of the country since late Tuesday, causing rivers to burst their banks, disrupting travel and triggering power outages. More than 60,000 homes were still without electricity on Wednesday evening, Yonhap said. The share price of insurers fell on fears that damage costs would run into tens of millions of dollars. At Chuncheon, about 100 km (60 miles) east of Seoul, soldiers were drafted in to help with the rescue operation after a wall of mud flattened the small hotels just after midnight. More than 40 holidaymakers, mostly university students, were sleeping in the inns when the landslide hit. "We were asleep and suddenly I heard a big sound, and then the ceiling fell down," Lee Beon-seok, a student, told a television station. Meanwhile, a slow-moving tropical storm killed at least 20 people in the Philippines as it dumped enormous amounts of rain that caused major flooding and landslides, authorities said Wednesday. Nock-ten, named after a Laotian bird, was expected to cause more damage in the mountainous northern areas of the main island of Luzon on Wednesday, while also bringing heavy rain to Manila, the state weather service said. Nock-ten, which struck the eastern Philippines on Tuesday, killed at least 20 people, with another nine missing, National Disaster Risk Reduction and Management Council chief Benito Ramos told reporters. Five of the victims died as a landslide buried parts of their village. About 645,000 people were also forced to flee their flooded homes in the coastal provinces of Albay and Camarines Sur in the southeast of Luzon where the storm first made landfall, according to Ramos. "Those two provinces are underwater," Ramos told AFP earlier. He said the government was waiting for the skies to clear and the seas to calm down before sending emergency supplies by air and water to those provinces. "We can't use the army trucks because the roads are flooded," he said. The council said dozens of flights had been cancelled because of the storm. Nock-ten had initially been expected to pass much closer to Manila, the nation's sprawling capital of 12 million people, and schools were closed across the city on Wednesday as it prepared for heavy rains. Ramos said Nock-ten was following an erratic course and that the latest forecast showed Manila and other densely populous areas would be spared the worst of the storm. "It did not follow its projected track," he said. Nevertheless, the new course would still mean about four million people in mountainous areas of northern Luzon were under threat, and landslides there were a danger. State weather forecaster Juanito Galang told AFP wind strength and rain volumes usually dissipated when a cyclone hit a wall of mountains, instead of going over flat land. "But the danger there is, if rain falls on a mountaintop, it will rush down slopes. The tendency is for the water to go down as flash floods or cause landslides," Galang said. "They're deadlier than ordinary floods because they occur suddenly and you are caught unaware," he said. Ramos also warned that all areas within 500 kilometres (310 miles) of the eye of the storm, which includes Manila, should expect rain until it moved out to the South China Sea on Thursday. An average of 20 storms and typhoons, some of them deadly, hit the Philippines every year. Storms killed 48 people on Luzon in May and June. Unusually heavy rains also killed 42 people last month in the country's south, an area that is normally spared typhoons and storms.
