Reply #50: Can you account for the spike?

[LARED]

The chart has three sets of data. The velocity measurements shown in two different ways -- both showing different velocity and time scales. Then there is the third chart showing displacement verses frequency.

So, seeing as it's all the same data just displayed differently, how do you explain that the spike does not manifest itself in all three data sets?


Do you have any experience interpreting seismic data? You seem to speak as someone that knows how to interpret this data in a definitive way.
