have now 2 raspberry shakes.
=== one inside = detect movements, door open/ close
=== one outside in a 2 feet deep hole sitting on a concrete slab covered with styrofoam on top and side, then wrapped into a plastic bag and finally covered with earth .
The PEO cable goes up through a U back down into the open earth then into the pipe back into the house.
The end of the pipes are filled with silicone so that water does not come in.
The 2 pipes do not connect so that movements of the outside pipe (e.g. rain, wind) do not enter the box with the pi.
Here some pictures of the setup:

The raspberry shake underground is ~ factor 10 better in terms of background..
Waiting for some earthquakes .. when they do heavy fracking again we will get some at strength ~ 2-4
will try to integrate them into indigo .. have my next project
possibilities:
1. earthquakes , only interesting for folks on the west coast, and fracking areas. - (in the US)
2. movement in the house .. and after some heavy programming may be we can do signal pattern analysis to distinguish e.g. door open/close, some one walking, washing machine is running, ac on,.. but thats a long way to go
