  14. USA Today Updated 10/4/2006 9:17 AM ET HANOI, Vietnam (AP) — Floods triggered by heavy rains submerged tens of thousands of Vietnamese homes Wednesday in the aftermath of Typhoon Xangsane, which killed at least 169 people in Vietnam and the Philippines, officials said. Vietnam's toll from the storm, which slammed into the country's central coast on Sunday, rose to 59 killed and four missing. The Philippines, which bore the brunt of the storm last week, reported 110 dead and 79 missing, as officials in both countries continued to tally the casualties and assess the damage. In the central Vietnamese port city of Danang, 22 people were killed and four were missing, said disaster official Huynh Van Thang. Officials previously had said 26 people were killed by the typhoon, most by collapsing homes. Another 14 people were killed in neighboring Quang Nam province, eight in Ha Tinh, four each in the provinces of Nghe An, Quang Tri and Thua Thien Hue, and three in Quang Binh province, disaster officials in these provinces said. The damage is estimated at $625 million, according to the National Floods and Storms Control Committee.

  32. Storm surge, not wind, causes most destruction and lives lost Storm surge (high seas) is a result of: 1. Low pressure (upward suction of the region of ocean beneath the hurricane’s low pressure influence) 2. Wind (upward pushing, shoving, of a region of ocean by the sustained winds)
