I did some stubby pencil work a while back and if I recall correctly, the mass energy conversion of 1kg of material (i.e. nuclear test) on the other side of the planet was orders of magnitude 'louder' than anything that LIGO has detected so far. It still suffers from having no chirp before that you get from two orbiting bodies that merge, but I think it would technically be detectable as a pop in the signal.
