Alright, let's begin by first going over the necesarry handseals for the jutsu.
You want to begin by creating theses seals *Shows*
Now, this technique works by using your chakra to form vibrations within the Earth resulting in a Earthquake.
It's a simple technique, and in order to convert the chakra into Vibrations a stomp is generally used to pour the chakra into the ground and then using the vibrations created by the stomp to produce a medium. Of course should a opponent have gone under ground when you use the technique, the vibrations will cause an extreme amount of damage to them usually resulting in the end of the battle.
Try to make me fall using the technique.
