有些活断层从来没有产生过引起人们注意的地震。由于许多岩层极其缓慢变形的共同作用的结果，它们在不断地滑动，其速度与板块的移动相一致，这种活动方式所产生的地震很轻微，不借助灵敏的地震仪，是不会觉察到的，这个过程叫蠕动。正在蠕动的断层不会发生严重的地质灾害，除非蠕动停止。通过对蠕动的断层和地震空白区的多年监视，研究人员能够确定出将来最可能发生地震的地区。本段文字中“其速度与板块的移动相一致”中的“其”指的是（　　）。

A、许多岩层的变形

B、许多岩层的滑动

C、活断层的滑动

D、活断层的变形

Eastern Quakes Can Trigger Big ShakesIn the first week of November 2011 ， people in central Oklahoma experienced more than two dozen earthquakes. The largest, a magnitude (量）5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few buildings and scared many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV, you see reports about all sorts of natural disasters. But the most dangerous type of natural disaster, and also the most unpredictable, is the earthquake.Researchers at the US Geological Survey ( USGS) estimate that several million earthquakes occur globally each year. That may sound scary, but people don’t feel many of them because they happen in remote and unpopulated regions. Many quakes happen under the ocean, and others have a very small magnitude.Scientists know about small, remote quakes only because of very sensitive electronic devices called seismometers (地震仪）.These devices detect and measure the size of ground vibrations (震颤）produced by earthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20, 000 earthquakes each year.Although earthquakes can happen anywhere in the world, really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen, on average, only once each year. Such big ones typically occur along the edges of Earth’s tectonic plates (构造板块）Tectonic plates are huge pieces of Earth’s crust (夕卜壳），sometimes many kilometers thick. Often, edges of these plates temporarily lock together. When plates push and scrape (擦）past each other earthquakes occur. On average, tectonic plates move very slowly — about the same speed as your fingernails grow.But sometimes earthquakes rumble (轰轰作响）through portions of the landscape far from a plate’s edges. Although less expected, these “mid-plate” small earthquakes can do substantial damage. Some of the biggest known examples hit the eastern half of the United States two centuries ago. Today, scientists are still puzzling over why the quakes occurred and when similar ones might occur.Whenever tectonic plates move, earthquakes happen. A Right B Wrong C Not mentioned
