Researchers(研究人员) at(at) the University(大学) of(of) Iowa(爱荷华) and() the U(U) .(.) S(S) .(.) Geological Survey(地质调查) have() found(发现) that(that) data(数据) gathered(收集) from() orbiting(轨道) satellites(卫星) can(可以) provide(提供) more() accurate(准确) information(信息) on(on) the impact(影响) of(of) large() earthquakes(地震),(,) which(which),(,) in(in) turn(转向),(,) can(能够) help(有助于) provide(提供) more() effective(有效) emergency(应急) response(响应).(.)
The satellite imagery(卫星图) provides(提供了) detailed(详细) information(信息) about(有关) where(where) the earthquakes(地震) occurred(发生),(,) how(how) big() the surface(地表) deformation(变形) was(was),(,) and() where(where) the earthquakes(地震) occurred(发生) relative(相对) to(to) population(人口) centers(中心),(,) typically(通常) within(within) two(two) to(to) three() days() of(of) the earthquake(地震).(.) This() information(信息) was(was) then(然后) incorporated(纳入) into(into) a(a) set(一套) of(of) operational(业务) response(响应) guides(指南) managed(管理) by() the USGS(USGS) National(国家) Earthquake(地震) Information(信息) Center(中心) (NEIC)((NEIC)) that() is(is) distributed(分发) to(to) decision(决策) makers(),(,) search(搜索) and() rescue(救援) operations(行动),(,) and(以及) other(其他) groups(小组).(.)

Mankin(曼金) processed(处理) radar(雷达) imagery(图像),(,) or() interferograms(干涉图),(,) from(from) a(a) 6.9(6.9) magnitude() quake(地震) that(that) struck(袭击) Indonesia(印度尼西亚) in(in) August(8月) 2018.(2018.) She() then(然后) used(使用) this(这个) imagery(图像) to(to) produce(产生) a(a) model(模型) of(of) the earthquake(地震) and() where(where) it() was(was) located(位置).(.) The USGS(美国地质勘探局) used(利用) this(这一) model(模型) directly(直接) to(to) update(更新) its(它的) predictions(预测) of(of) ground(地面) shaking() and() earthquake(地震) impact(影响) that() were(were) incorporated(结合) into(into) its(它的) disaster(灾害)-()response(响应) systems(系统中).(.)
