国外爱好者拍的,智力大地震后拍摄的,星点拉的线中间有明显移位,这一方法精确的记录了余震的情况

In Chile, astronomers know the ground is still shaking. They can see it in the stars. Colin Legg reports from the Andes east of Santiago: "I made this 88-second exposure on Sunday morning, Feb. 28th, less than 24 hours after the big 8.8-magnitude quake. It records the movement of the Earth in the star trails during an earth tremor."
Earthquake experts say the shaking will continue for months. Indeed, in the days after the "Big One", Chilean seismometers have recorded more than ten aftershocks in the range 6th to 7th magnitude, and more than two hundred aftershocks stronger than 4th magnitude. A tip for southern astrophotographers: Keep your exposure times short. The stars over Chile could be wobbling for some time to come.
在智利,天文学家们知道大地依然在摇动。他们可以通过观测星星来获取信息。Colin Legg从圣地亚哥以东的安第斯山脉发来报告说:“我在二月28日周日的早晨拍摄了这张曝光88秒的照片。智利8.8级大地震刚刚过去不到24小时。它记录了星点在地壳震颤中的移动。”
地震专家们说地震还会持续几个月。事实上,在大地震过后的几天里,测震仪已经记录下了多余10次位于智利范围内的6到7级的余震,以及多于200次高于4级的余震。对于南部的天体摄影家的忠告:将曝光时间缩短,智利上空的恒星可能在某时会颤动
