One pertinent question in the wake of the earthquake near Aceh (亚齐省) and the tsunami (海啸) it generated is how much notice of an approaching wave can be given to vulnerable people without the risk of crying "wolf" too often. Earthquakes themselves are unpredictable, and likely to remain so. But detecting them when they happen is a routine technology. That was not the problem in this case, which was observed by monitoring stations all over the world. Unfortunately for the forecasters, although any powerful submarine earthquake brings the risk of a dangerous tsunami, not all such earthquakes actually result in a big wave, and false alarms cost money and breed cynicism.
On top of that, most "tsunamigenic" earthquakes, which are caused when the processes of plate tectonics force heavy, oceanic crustal rock below lighter, continental rock to create a deep trench at the bottom of the sea, occur in the Pacific, which is almost surrounded by such trenches. In the Indian Ocean, deep trenches are confined to the southern coast of Indonesia, and tsunamis are rare. Since most of the countries affected by this tsunami are poor, or middle income at best, and monitoring costs money, this might suggest that a fatalistic approach to the question is reasonable. But American and Japanese experience suggests that effective monitoring need not be that expensive. These two countries have networks of seabed pressure detectors that can monitor tsunamis and indicate whether and where evacuation is necessary data they share with their Pacific neighbours. A system of seven detectors, run from Hawaii, cost about $18m to develop, and the experience gained doing So means a similar system might now be set up for as little as $2m. So, to the sound of stable doors being bolted firmly shut, politicians in South East Asia and Australia are proposing one for the Indian Ocean;
Even if you have an effective detection system, though, it is useless if you cannot evacuate a threatened area. Here, speed is of the essence. Computer modeling help shows which areas are likely to be safest, but common sense is often the best guide: nm like the wind, away from the sea. Evacuation warnings, too, should be easy to give as long as people are awake. Radios are ubiquitous (无所不在的), even in most poor places. It is just a matter of having systems in place to tell the radio stations to tell people to run. The problem was that no one did.
It is implied in the last two paragraphs that
选项
答案
the heavy loss in the Southeast Asia tsunami could have been less
解析
参见第2段第7行:... effective monitoring needs not to be that expensive,所以东南亚地区国家本应能够建立有效的监控系统。再参见最后1段第3至最后1行:common sense is the best guide: run like the wind, away from the sea; Evacuation warnings,too should be easy to give;Radios are anywhere, even in poor countries; It is just a matter of having systems in place to tell people to run.以上可以看出,有好几种简单的办法使人逃生,减少损失,可是遗憾的是:no one did。
