There are no major faults on the world because there are no plate tectonics.
Very rich in volcanic activity all around the world. This is because there is a very active flow of magma under the crust. This is caused by the pulling of the curst as the moon they live on turns on its axis. Along with the heat at the center of the world and the friction on the curst this heats the insides of the world like a pressure cooker on a stove.
Earthquakes on this world is caused by the movement of magma below the surface. Areas will become clogged and the vents and channels below the surface of the world sometimes break causing ripples throughout the land.
