If a script with this event exists in the parent prim of a link set, and a child prim collides with the land, the parent prim's land_collision event will be triggered. However, if the child prim has a script (even one without a land_collision event) in it, land collisions will not
be passed unless the child prim's script contains llPassCollisions
