Rumbling Rocky sound

rock slide quake sound.

so i made this when making a video as an activity with some friend (nothing big probably not even going to be published publicly) and i decided i would put it up here after using some of the sound from this site.

i used a program called Audacity to edit multiple recordings together to achieve the right effect (in this cause a wall crumbling to the ground) i used a thunder recording as well as rocks hitting the ground some explosion sound and a gravely sound.
i didnt record any of the samples i use myself, here are the samples i used.
