From Yahoo! News - Elders' Sea Knowledge Spares Some Thais:
"By the time killer waves crashed over southern Thailand last Sunday the entire 181 population of their fishing village had fled to a temple in the mountains of South Surin Island, English language Thai daily The Nation reported.
'The elders told us that if the water recedes fast it will reappear in the same quantity in which it disappeared,' 65-year-old village chief Sarmao Kathalay told the paper.
So while in some places along the southern coast, Thais headed to the beach when the sea drained out of beaches 'the first sign of the impending tsunami ' to pick up fish left flapping on the sand, the gypsies headed for the hills. "
