The elephants started trumpeting at first light, about the time an earthquake measured at a magnitude of 9.0 cracked open the sea bed off Indonesia's Sumatra island. The elephants soon calmed down. But they started wailing again about an hour later and this time they could not be comforted despite their mahouts' attempts at reassurance. "The elephants didn't believe the mahouts. They just kept running for the hill," said Wit Aniwat, 24, who takes the money from tourists. "The mahouts managed to turn the elephants to lift the tourists onto their backs," Kulada said. The tsunami drove up to 1 km (1,000 yards) inshore, but it stopped short of where the elephants stood.
