问题 单项选择题

下列关于水上消防站选址要求的表述,正确的是()

A.与陆上基地之间的距离至少为500m

B.宜布置在城市港口、码头等设施的下游

C.可布置在河道转弯处

D.若辖区水域或沿岸有危险化学品设施,消防站陆上基地应距危险化学品设施不小于200m

答案

参考答案:D

解析:水上消防站选址要求:(1)宣布置在城市港口、码头等设施的上游,不应布置在河道转弯处及电站、大坝附近;(2)若辖区沙尘沿岸有危险化学品设施,消防站应布置在上游处,消防站陆上基地距危险化学品设施不小于200m;(3)消防站趸船和陆上基地之间的距离不大于500m,且没有铁路、城市主干路、快速路和高速公路分隔。

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.
