Brett,

I am curious about the installation enclosure for your seismometer.  It 
looks like a granite slab surrounded by a plastic enclosure.  Is this 
located in a basement or is it outside.  How do you insure it is waterproof? 
What is the granite slab setting on?  What type of plastic enclosure are you 
using.

Thanks so much,
Kay Wyatt
