为什么有这么多月震？对阿波罗登月期间留在月球上的地震仪的分析显示，在距离月球表面100公里的范围内发生了数量惊人的月震。事实上，在1972年至1977年的记录数据中，探测到62次月震。其中许多月震的强度不仅足以移动月球公寓里的家具，而且月球坚硬的岩石会持续振动数分钟，比地球上较软的岩石地震要长得多。月震的原因尚不清楚，但一个主要的假设包括来自地球的潮汐引力和地球的相对加热。无论其来源如何，未来的月球住宅都需要能够承受频繁的震动。图为阿波罗11号宇航员巴兹·奥尔德林站在最近安装的月球地震仪旁，回望着登月舱。探索你的宇宙：随机APOD生成器

Why are there so many moonquakes? Analyses of seismometers left on the moon during the Apollo moon landings reveal a surprising number of moonquakes occurring within 100 kilometers of the surface. In fact, 62 moonquakes were detected in data recorded between 1972 and 1977. Many of these moonquakes are not only strong enough to move furniture in a lunar apartment, but the stiff rock of the moon continues to vibrate for many minutes, significantly longer than the softer rock earthquakes on Earth. The cause of the moonquakes remains unknown, but a leading hypothesis include tidal gravity from -- and relative heating by -- our Earth. Regardless of the source, future moon dwellings need to be built to withstand the frequent shakings.
