令人驚訝的月震
Moonquakes Surprisingly Common

發表日期:2025-04-06
為什麼會有這麼多月震? 對阿波羅登月期間留在月球上的地震儀的分析表明,在距月球表面 100 公里範圍內發生的月震數量驚人。 事實上, 1972 年至 1977 年間記錄的資料中發現了 62 次月震。 其中許多月震的強度不僅足以移動月球公寓中的傢俱,而且月球堅硬的岩石會持續震動許多分鐘,比地球上較軟的岩石地震的震動時間要長得多。 月震的原因仍然未知,但一個主要的假設包括來自地球的潮汐引力和地球的相對加熱。不管是什麼原因,未來的月球住宅都需要建造得能夠承受頻繁的震動。 圖為阿波羅 11 號宇航員巴茲-奧爾德林(Buzz Aldrin)站在最近部署的月球地震儀旁,回望登月艙。 探索你的宇宙隨機 APOD 生成器
原文: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.
