  We conduct a thorough analysis of seismic and acoustic data from the
so-called `Interstellar Meteor' which entered the Earth's atmosphere off the
coast of Papua New Guinea on 2014-01-08. We conclude that both
previously-reported seismic signals are spurious -- one has characteristics
suggesting a local vehicular-traffic based origin; whilst the other is
statistically indistinguishable from the background noise. As such,
previously-reported localisations based on this data are spurious. Analysis of
acoustic data provides a best fit location estimate which is very far
($\sim$170~km) from the reported fireball location. Accordingly, we conclude
that material recovered from the seafloor and purported to be from the meteor
is almost certainly unrelated to it, and is likely of more mundane
(non-interstellar) origin.
