This is 1/100 the magnitude, correct?

Anybody who’s been in a 5-6 M earthquake will rightly fear a 7M.

It's a bit more involved than that; it is logarithmic, but the base is somewhat ambiguous. The issue is whether the value one is taking the logarithm of is the maximum amplitude measured by seismographs, or the total energy released which of course must be estimated by more involved means and takes into account the depth of the fault failure and the area (or perhaps) volume over which the failure extended.

IIRC, it would be 1/1,000 the magnitude. (each rise of 1 level of magnitude is 32 x above the lower one, and 32x32=1,000)
