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 <jats:italic>M<\/jats:italic>\n                  <jats:sub>\n                     <jats:italic>w<\/jats:italic>\n                  <\/jats:sub> of \u223c5.3 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 \u223c40 km, while moderate to light shaking may extend beyond \u223c50 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 \u223c0.1 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.<\/jats:p>","DOI":"10.3847\/psj\/ad1332","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T14:56:07Z","timestamp":1706194567000},"page":"22","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":27,"title":["Tectonics and Seismicity of the Lunar South Polar Region"],"prefix":"10.3847","volume":"5","author":[{"given":"T.
