Some African tribes turn funerals into festivals in which being loud and hitting the ground dancing is a tribal thing. The idea is to keep the soul of deceased in festival mood as the his journey to the afterlife begins. The common belief is the soul will come haunt the tribe if it didn't make it peacefully to the afterlife.
So, I would say "Kicking the Ground" is more suitable here, since making noise is intentional behavior to grasp the attention of souls buried in the ground.
