浅层月震被认为是构造成因。然而，造成这些月震的地质结构尚不清楚。在这里，我们报告的网站月震可能发生沿着年轻的叶状悬崖在薛定谔盆地。我们对月球勘测轨道器和月船一号图像的分析显示，在薛定谔盆地的不同部分有四个叶状悬崖。陡崖横切小的新的撞击坑（1500巨石与痕迹和反弹的痕迹。它们的起源在很大程度上受到最近的撞击事件的控制。从一个直径14公里的撞击坑喷出的射线和次级撞击坑链穿过薛定谔，并引发了大约17 Ma的巨大巨石福尔斯坠落。因此，最近的浅层月震和撞击事件的结合引发了薛定谔盆地的巨石福尔斯。
Shallow moonquakes are thought to be of tectonic origin. However, the geologic structures responsible for these moonquakes are unknown. Here we report sites where moonquakes possibly occurred along young lobate scarps in the Schrödinger basin. Our analysis of Lunar Reconnaissance Orbiter and Chandrayaan‐1 images revealed four lobate scarps in different parts of the Schrödinger basin. The scarps crosscut small fresh impact craters (1500 boulders associated with trails and bouncing marks. Their origins are largely controlled by recent impact events. Ejecta rays and secondary crater chains from a 14 km diameter impact crater traversed Schrödinger and triggered significant boulder falls about 17 Ma. Therefore, a combination of recent shallow moonquakes and impact events triggered the boulder falls in the Schrödinger basin.
