This is the content for Lesson 1. Typhoon Maemi was the most powerful typhoon to strike South Korea since records began in 1904. Maemi formed on September 4, 2003 in the western Pacific and became a typhoon on September 8. Passing over the Japanese island of Miyako-jima on September 10, it left 95 percent of residents without power and caused 58.5 mm (2.30 in) of rainfall in an hour and 402.5 mm (15.85 in) in 24 hours. Maintaining much of its intensity, it made landfall west of Busan, South Korea, on September 12, where winds reached 154 km/h (96 mph). The port sustained heavy damage, restricting exports for months. On Jeju Island, it produced a peak wind gust of 216 km/h (134 mph) and a minimum pressure of 950 mbar (28 inHg), both records for the country. Nationwide, high winds destroyed about 5,000 houses and damaged 13,000 buildings, leaving 25,000 people homeless. Crop damage resulted in the poorest rice harvest in 23 years. Across South Korea, Maemi killed 117 people, and damage totaled 5.52 trillion won (US$4.8 billion).
