Breaking up data by county

I am trying to figure out a simple automated way (by script or model building or whatever works) to break up polygons into counties. The end goal is to have all of my data (including precipitation and seismic hazard and other parameters that do not respect political boundaries---see attached image) in county format so that I can use modeling methods such as GWR on a single county shapefile with all parameters.

My issue is that I don't know how to turn variables like seismic hazard into a representative county coverage. I think I should be able to use a script to clip the seismic hazard individually for each of the 96 counties. Then I would have only a few polygons of seismic hazard inside an individual county. Next I could take compute an area weighted average of those polygons to get the value for the individual county.

I can do this process by hand for one parameter at a time and one county at a time, but that won't work for 96 counties and multiple parameters.

Thanks.
