This article is really bad.. > having lost around 50 meters in circumference over the last few hundreds of millions of years Okay small amount, nothing to worry about for mere mortals. And ZERO references to this 'fact' > Since the moon’s crust is like a hard outer shell around this shrinking core, it naturally starts to crack. That’s when moonquakes are produced — and they can be quite strong. No reference to what they're talking about, just a "Trust me bro" after an assertive `—` pause before saying "They can be quite big"? > For instance, the new study found that a large thrust fault near the lunar South Pole might have been responsible for a magnitude 5 moonquake over the last few million years. No references to what the author is talking about, and magnitude 5 ? Of what ?? It cant be relative to an earth mag 5 because that wouldn't make sense? Or maybe it is and they correlated / mapped the magnitudes from earth to the moon ? That would be a better article to read. Having looked up some referenced stuff online, the largest recorded was around 5.. > Observed moonquakes have been mostly less than 3 on the Richter scale; the largest recorded ones have a magnitude between 5 and 5.7. https://www.sciencedirect.com/science/article/abs/pii/B9780120885893500165 https://www.sciencedirect.com/science/article/abs/pii/B97801... > Moonquakes shake up plans for human settlements. Nonsense. It feels like an article given in bad form to chat gpt to sound and read better. If it wasn't then the author is even worse than that. Absolute nonsense.

Dear idiot, I'm the author the article. Here's reference you asked for because you were too incompetent to find: "The lunar south pole regions are subjected to global stresses that result in contractional deformation and associated seismicity. This deformation is mainly expressed by lobate thrust fault scarps; examples are globally distributed, including polar regions. One small cluster of lobate scarps falls within the de Gerlache Rim 2 Artemis III candidate landing region. The formation of the largest de Gerlache scarp, less than 60 km from the pole, may have been the source of one of the strongest shallow moonquakes recorded by the Apollo Passive Seismic Network. The scarp is within a probabilistic space of relocated epicenters for this event determined in a previous study. Modeling suggests that a shallow moonquake with an Mw of ∼5.3 may have formed the lobate thrust fault scarp. We modeled the peak ground acceleration generated by such an event and found that strong to moderate ground shaking is predicted at a distance from the source of at least ∼40 km, while moderate to light shaking may extend beyond ∼50 km. Models of the slope stability in the south polar region predict that most of the steep slopes in Shackleton crater are susceptible to regolith landslides. Light seismic shaking may be all that is necessary to trigger regolith landslides, particularly if the regolith has low cohesion (on the order of ∼0.1 kPa). The potential of strong seismic events from active thrust faults should be considered when preparing and locating permanent outposts and pose a possible hazard to future robotic and human exploration of the south polar region." https://iopscience.iop.org/article/10.3847/PSJ/ad1332 https://iopscience.iop.org/article/10.3847/PSJ/ad1332 Here's an article from a reputed source that essentially covers the same points: https://www.washingtonpost.com/climate-environment/2024/02/04/moon-shrinking-moonquakes-nasa/ https://www.washingtonpost.com/climate-environment/2024/02/0...
