Yes - start with
http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/points.html#attribute-based-point
which shows how to set radius by magnitude, there are other sections
which will cover transparency and color which you can set to
properties as with radius. You may also need to look at functions to
do some normalization of variables
(http://docs.geoserver.org/stable/en/user/filter/function_reference.html#math-functions).
