  Images covering the central 450 by 100 arcsecond (about 8.0 by 2.0 kpc) of
NGC 5128 (Centaurus A) obtained using SCUBA at 850 and 450 micron with beam
sizes of 14.5 and 8 arcsecond respectively, are presented. These data are
compared with those obtained at other wavelengths, in particular the optical,
mid-infrared, and far-infrared continuum. The sensitive 850 and 450 micron
images show that the submillimeter (submm) continuum morphology and spectral
index distribution of Centaurus A comprise four regions: an unresolved AGN
core, an inner jet interacting with gas in the dust lane, an inner disk of
radius roughly 90 arcsecond, and colder outer dust. The inner disk has a high
surface brightness, reverse-S-shaped feature in the 850 and 450 micron images
that coincides with the regions of intense 7 and 15 micron continuum and a
region of active star-formation. The infrared (IR) and submm images appear to
reveal the same material as predicted by a geometric warped disk model
consisting of tilted rings. We suggest this scenario is more plausible than
that recently proposed in literature suggesting that the mid-IR emission in
Centaurus A is primarily from a bar, with a structure that is different from
the extended warped disk alone. A dust mass total of 2.2 million solar masses
has been calculated within a radius of 225 arcsecond, 45% of which is in the
star-forming region of radius about 90 arcsecond about the nucleus.
