  Neptune is a gas giant, which means that it doesn’t have a solid surface like Earth. This means that earthquakes (as we know them on Earth) don’t occur.

  As Katie wrote, no earthquakes on Neptune because it is all gas, but there has been a few interesting things with gas giants like Jupiter.
  
  In 1994 a comet collided with Jupiter as was the first ever recorded major collision in the solar system – https://en.wikipedia.org/wiki/Comet_Shoemaker%E2%80%93Levy_9
  
  Also did you know that on Earth, earthquakes last up to 2min, but on the Moon, “Moonquakes” can last more than 10 minutes ?…that’s because there is no water like the Earth ocean to attenuate the vibration of the quakes.
