Shallow Moonquakes Could Cause Strong Ground Shaking
According to a recent study conducted by scientists from NASA, Arizona State University, and the University of Maryland, the moon’s south polar region could experience shallow moonquakes capable of producing strong ground shaking. The research, led by Tom Watters of the Smithsonian Institution, suggests that these moonquakes could result from slip events on existing faults or the formation of new thrust faults.
Considerations for Future Lunar Outposts
The study highlights the importance of considering the global distribution of young thrust faults and their potential to be active when planning the location and stability of permanent outposts on the moon. “The potential to form new thrust faults from ongoing global contraction should also be taken into account,” Watters explains. These findings have significant implications for the upcoming Artemis mission and the safety of astronauts, equipment, and infrastructure.
Moonquakes vs. Earthquakes: Key Differences
Unlike earthquakes on Earth, moonquakes have distinct characteristics. A video shared on the Weather Channel’s website explains that moonquakes are more likely to trigger landslides compared to their terrestrial counterparts. Nicholas Schmerr, a co-author of the study and associate professor of geology at the University of Maryland, emphasizes the need to prioritize safety measures as the crewed Artemis mission approaches.
The Moon’s Shrinking Interior
In 2019, a study revealed that the moon has been gradually shrinking as its interior cools. Over the past several hundred million years, it has become approximately 150 feet thinner. The recent study on moonquakes was funded by NASA’s Lunar Reconnaissance Orbitor mission, launched on June 18, 2009.
