On the night of August 17, 1959, at about 20 minutes before midnight, the ground in the vicinity of Yellowstone National Park began shaking violently. At the time there was a rumbling sound, something like a huge truck would make. Both the heaving of the ground and the noise were very frightening but lasted not quite 45 seconds.
1959年8月17日的晚上,大約午夜前20分鐘,黃石國(guó)家公園附近大地開始猛烈搖動(dòng)。同時(shí),大地發(fā)出如同重型卡車發(fā)出的轟響。大地的升降和 嘯叫都令人非常害怕,但是一切不超過45秒。
