The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.

(答案→)C 解析：本文介绍了智利的地震移动城市，介绍了移动最厉害的城市和原因。【小题1】主旨题:从第一段的句子：The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west,可知答案是C【小题2】细节题：从第一段的句子：The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west,和第三段的句子： Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest.可知Concepcion是移动最大的。选A【小题3】猜词题：从第四段的句子：an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean.可知这个词组的意思是太平洋周围的地区。选D【小题4】细节题：从第五段的句子：Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.可知CAP是在Mike Bevis的领导下。选A。
