Moonquakes

Moonquakes are seismic events that occur on the Moon, similar to earthquakes on Earth. They are caused by various factors such as tidal stresses from the Earth's gravitational pull, thermal expansion and contraction due to temperature changes, and natural relaxation of the Moon’s crust from its formation. Moonquakes can last longer and be more prolonged than Earthquakes, and some are relatively strong. They are detected by seismometers left on the lunar surface during the Apollo missions, helping scientists understand the Moon's internal structure and geological activity.
