Observations show small vibrations preceding meteorite impacts, likely due to seismic precursors or micro-fracturing. Dust movement and subtle surface shifts were recorded by seismometers. These quivers last seconds before impact. They provide data on stress propagation. Predicting impacts from precursors could be valuable for future colonies. Even small meteors produce measurable disturbances.
It matters for real-time hazard monitoring and planning. Early detection improves safety.
It also improves understanding of impact physics and energy transfer in low-gravity environments.
Lunar surface can quiver several centimeters before tiny impacts.
