Can you please delete your answer on my question about my partner having anger issues? It was a troll ask and I want to delete it but can't unless all the answers are deleted. Thanks

Yes. Parts expand and contract with changes in temperature, meteorite impacts cause shaking and there are tidal forces from Earth and the Sun. However, they're never as strong as the strongest earthquakes. There are seismometers there, left by the astronauts.

Yes, there are. The Moon is far from geologically or seismically dead. Most moonquakes are are an average Richter scale of 3 2, but the largest and strongest are 5.7.
Most, but not all Moonquakes are caused by tidal interactions?with Earth. Others are caused by more massive meteorite impacts. The Moon still has a?liquid magma layer 30 kilometers thick around a massive core that still has not cooled off and crystallized after more than 4 BILLION years

I've been through a 5.8 Earth quake on September 3, 2016 that was?a fracking induced earthquake. Now that fracking is banned in much of Oklahoma there are fewer and lower magnitude earthquakes.

There are moonquakes, but they are not thought to be due to plate tectonics or movement of magma as on Earth. The current theory is the moon is cooling and therefore shrinking, causing quakes.

Nope. The Moon has NO quake activities as it has no volcanos.
