Yet at Yala National Park, just up the coast from where the destruction was most severe, all the elephants, leopards, deer and other wild animals managed to survive the mighty waves, said H.D. Ratnayake, deputy director of the country's wildlife department.
"I haven't seen any effects on the animals," he said. "They all escaped." Asked to explain the survival of the animals, he said: "They had a feeling. Maybe it was the sound waves."
