MINI BELIEVE IT OR NOT –

Studying data collected in the ’70s, scientists discovered that the moon has regular moonquakes.

  • Between 1969 and 1972, Apollo astronauts placed seismometers on the moon
  • Scientists discovered there are four different types of moonquakes
    1. Deep quakes are caused by tides and happen about 700 km below the surface
    2. Vibrations from the impact of meteorites
    3. Thermal quakes are caused by the expansion of crust when it first reaches the sun after two weeks of lunar night
    4. And shallow quakes that happen 20-30 km below the surface
  • The quakes can register up to a 5.5 on the Richter scale and last longer than 10 minutes
