Where we areFour ideas. One record.
Now read a real one.
A real blast is many tones at once, so the trace is messy. The pure tone is the building block, so you can check the sums.
One axis of a simulated blast, from a ShotTrack ViB placed 300 m from a quarry bench, about three football fields away. Tap each marker.
How far
The ground here moved 0.12 mm at most, about one sheet of paper. You would not see it. The unit did.
