Study Helps Predict Big Mediterranean Quake Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365. Using radiocarbon dating techniques, simulations and computer models, the researchers recreated the ancient disaster in order to identify the responsible fault. "We are saying there is probably a repeat time of 800 years for this kind of earthquake," said Ms. Beth Shaw, an earthquake scientist at the University of Cambridge, who led the study. Scientists study past earthquakes in order to determine the future possibility of similar large shocks. Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region, Ms. Shaw said. The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300, which means the next powerful one could come in the next 100 years, she added in a telephone interview. Ms. Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion, she said. Their computer model suggested an 8 magnitude quake on the fault would produce a tsunami that floods the coastal regions of Alexandria and North Africa, the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik. This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta, likely killing tens of thousands of people, she said. It is fun to identify the fault for the AD 365 earthquake and tsunami.

Text 2People who begin to go deaf in adult life have different problems from those who are born deaf. They have to learn different ways of behaving and different ways of communicating—perhaps at a time when learning is not at all that easy. A hearing aid is not a complete solution to the problem. The sound perceived by the deaf person through a hearing aid is distorted and appears to have more background noise than is heard by someone with normal hearing. Deafened people have to lipread as well.Lipreading is difficult, demands intense concentration, and an uninterrupted direct view of the speaker’s face. No other activities can take place at the same time: the lipreader has to stop eating, stop reading, stop washing up, stop mending, stop everything in order to concentrate on hearing. It is not a question of stupidity or bad temper—as it sometimes appears to be—but a question of being very easy to misunderstand when the sound is distorted. Remember what it’s like trying to communicate on a very bad telephone line. Frustrating, isn’t it The deaf have to face that all the time.A useful way of looking at the problem is to see the deaf person as a foreigner—to treat them as if you were in a foreign country. You would speak more clearly, slowly and raise your voice slightly. And you’d use gestures to make your meaning clear, as well as have no hesitation in using pencil and paper to be absolutely certain. You can do all those things with the deaf—as well as making sure you don’t obscure your mouth with your hand, a pipe or a cigarette.Another point quite often overlooked is that a hearing aid may be quite efficient and useful in a quite carpeted room—but try it in the high street in the rush hour, in a noisy car, in a railway station ticket office, a cinema or a concert hall and you’ve got a really difficult problem to distinguish speech. So don’t suggest to or encourage deaf people to go to functions which are going to make their disability appear worse—and increase their sense of failure.On the other hand careful selection of cinemas with good sound systems is important and you should experiment to find out where the best seats are for hearing, fitting adaptors for radio and television, observing which friends are easier to understand, and making sure that people talking are well-lit and all useful and positive activities. It can be implied that ().
A. it sometimes looks stupid when lipreaders have to stop whatever they are doing in order to understand what others say
B. a lipreader can do two things at the same time
C. you will be misunderstood if the sound is distorted by the hearing aid
D. deaf people can get frustrated in places where their hearing aids don’t work so well
