月球上有地震嗎?


月球上存在地震(月震)現象,有一些相關學說,因為我不大懂就不羅列了,下面是美國地質調查局官方網站上的說明:

Moonquakes (「earthquakes」 on the moon) do occur, but they happen less frequently and have smaller magnitudes than earthquakes on the Earth. It appears they are related to the tidal stresses associated with the varying distance between the Earth and Moon. They also occur at great depth, about halfway between the surface and the center of the moon.
