FRED DE SAM LAZARO: Rebuilding their lives may be the more immediate worry, but never too far below the surface is concern about another tsunami. The Thai government is building an early warning system. The man in charge was called out of a retirement. Meteorologist Smith Dharmasaroja had called for such a system ten years ago. He'd generated controversy at the time, saying that a tsunami was imminent. SMITH DHARMASAROJA: People called me a lot of names, and criticized me and called me a mad man, and especially some government officials told me that I destroyed the tourism industry in Thailand. FRED DE SAM LAZARO: Saying you were scaring away tourists in other words? SMITH DHARMASAROJA: Yes, that's right. FRED DE SAM LAZARO: This Bangkok center now monitors American, Japanese and other global geologic and news sources for information. They are looking for seismic activity that could affect the Thai coast. Earthquakes are sometimes followed by high waves. So as soon as one is detected, the center is intended to send warnings to shoreline communities in case a tsunami ensues. SMITH DHARMASAROJA: We know exactly what location of epicenter, and we calculate the time of arrival, estimated time of arrival of the tsunami. We will send this information to satellite, and this satellite will send signal to the warning tower to operate. You probably have 25 minutes or 30 minutes. FRED DE SAM LAZARO: To seek higher ground? SMITH DHARMASAROJA: Yes. FRED DE SAM LAZARO: So far just three of a planned 62 warning towers have been installed and the system hasn't worked well. Two quakes did actually occur this year. They did not trigger tsunami waves. However, in both cases emergency messages did not reach all the televisions and cell phones they were supposed to in beach communities. And in fishing villages like Bonsai Kai, it was even worse. Village headman Laiman Sau says the public address system hasn't worked since it was hit by last year's tsunami. Evacuation orders had to come by word of mouth. As Tai officials work out the bugs and build the early warning system, the informal telephone and door-to-door approach will likely work for some time. The force and fury of the last tsunami is enough to keep everyone here on their toes for a long time. JIM LEHRER: Since that report was completed, Indonesia has activated the initial phase of its early warning system. Surface buoys and sensors on the bottom of the ocean are in place to detect tremors. The full system is scheduled to be in place by 2007. |
