Sutton driveway ice chipping

Clearing

Testing

Notes:

[Finally] One day after I cleared some ice off the area in front of the garage, I checked to see what my RSB recorded. The spikes were interesting and were likely from my ice chipping to loosen ice to scrape off.

A few days later I went outside to the far end of the pavement and tapped my shovel there once. Then moved a third of the way back and tapped twice. Then repeated two more times.

This is one final example that:

1) It's easy to make the Earth move.

2) These Shakes are not toys, but amazingly sensitive instruments.
