虽然地方震引起的震动在这之前已经被记录到好几次了，但是还没有人记录到遥远地震传来的地震波。
Although the shaking of local earthquakes had been recorded several times before, nobody had ever registered the waves from a far away earthquake.
但由于许多地震发生在偏远地区抑或地震级数很小，他们就未报道。
However, many go undetected because they hit remote areas or have very small magnitudes.
