A Great Quake Coining?
Everyone who lives in San Francisco knows that earthquakes are common in the bay area and they can be devastating. In 1906, for example, a major quake destroyed about 28,000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when the next "Big One" will strike. It’s bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults are places where pieces of Earth’s crust(地壳)slide past each other. When these pieces slip, the ground shakes.
To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.
One new finding about the 1906 earthquake is that the San Andreas faults split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂)at about 2.7 kilometers per second. During bigger quakes, however, ruptures can happen at rates faster than 3. 5 kilometers per second.
At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses(脉冲)travel away from the city during the 1906 event. As bad as the damage was, it could have been far worse.
Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the earthquake has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.
New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city’s buildings are old and weak. Analysts suggest that another massive earthquake would cause extensive damage.
People who live there tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it’s not a matter of if the Big One will hit. It’s just a matter of when.
The San Francisco area is located above several active fault lines.
选项
A、Right.
B、Wrong
C、Not mentioned
答案
B
解析
题干大意:旧金山地区位于几个活动断层带之上。本题给出的信息是错误的。文章第一段提到:At least seven active fault lines run through the San Franciscoarea.至少七种活动断裂带穿越了旧金山地区。由此可知题干所述缩小了文章信息的范围,所以给出的信息是错误,故答案选B。
