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 1906 earthquake in San Francisco is the most severe one in American history.
选项
A、Right
B、Wrong
C、Not mentioned
答案
C
解析
题干大意:旧金山1906年的地震是美国历史上最严重的一次。文章没有谈到这方面信息。文章第一段提到:In 1906,for example,a major quake destroyed about 28,000 buildings and killed hundreds,perhaps thousands of people.1906年地震破坏性大造成了很大的损失,但是没说是最严重的。所以题干所述文章并无提及,故答案选C。
