VANUATU A woman and her child stand next to an uprooted tree near their home in Port Vila, the capital of the Pacific island nation, on March 16. A powerful cyclone with winds of more than 185 m.p.h. (297 km/h) struck the archipelago three days earlier, destroying or damaging up to 90% of buildings in some areas and killing at least 11 people. Many survived by sheltering in sturdy buildings like schools and churches
