You will be looking at the magnitude of the trough – its largest negative amplitude
The blow-up on the left shows extremely negative numbers
where the trough is vertical, it has been clipped for display purposes
Compare this response to the blow-up on the right
On the right, where water is the pore fluid, the response is weaker (less negative numbers)
Traces are
‘clipped’
