  Bounds on masses and abundances of Strange Quark Nuggets (SQNs) are inferred
from a seismic search on Earth. Potential SQN bounds from a possible seismic
search on the Moon are reviewed and compared with Earth capabilities. Bounds
are derived from the data taken by seismometers implanted on the Moon by the
Apollo astronauts. We show that the Apollo data implies that the abundance of
SQNs in the region of 10 kg to one ton must be at least an order of magnitude
less than would saturate the dark matter in the solar neighborhood.
