The same gravitational force responsible for creating tides on Earth could be causing deep quakes on the moon, a new study confirms. A new analysis of data gathered by the Apollo missions confirms that tidal stress – the gravitational pull of the moon on the Earth and of the Earth on the moon – is responsible for causing deep moonquakes, the lunar equivalent of earthquakes.

Seismometers placed on the moon during the Apollo 12, 14, 15 and 16 missions revealed the m...
