[MacGyverGod]

This is something I've been meaning to ask for some time now. When MacGyver, Jack and Mukti are getting water from the spring in Mountain of Youth the ground rumbles twice resulting that the water stops flowing despite it being eternal. Mukti explains it as the devil's rumbling since it is a forbidden place and many people haven't returned from the spring. MacGyver thinks however the water is being diverted with a strong pump.

So this is again MacGyver rationalizing it with a scientific explanation. But what kind of pump makes the ground rumble like that to divert water? Can it do that? Diverting water with a strong enough pump can cause detectable vibrations like that? I think it's just the logical explanation and maybe the rumblings are an easy way to keep the gullible people of Ammukash away from the spring and probably the dangerous Kabulstani soldiers for their own good of course.

But... what if it isn't? What if it's not the divertion of the water but the actual devil's rumbling or other higher and inexplicable forces? Jack did say it was a mystical place. What if there is more than meets the eye here? What do you guys think is the Devil's Rumbling?

If an underground aquifer/reservoir doesn't have water in it, the ground surrounding the area would start shifting, and lead to the rumbling. It's a good coincidence that the earthquake/rumbling started right as Mac arrived, but I assume the pumping had been going on for a few hours or days before Macgyver's arrival - which would have caused the aquifer/reservoir to already be partially depleted.

While I am not a geologist, I assume the technical term would be similar to what is described here - https://en.wikipedia.org/wiki/Groundwater-related_subsidence

I think the plot of the 007 movie "A view to a kill" from 1985 involved pumping water out of an underground reservoir and starting an earthquake - and while the plot of that film involved a bomb as a catalyst device, Macgyver could have got the idea from there, since we know he is familiar with James Bond films.

In addition, here are a few articles involving drilling the ground and leading to earthquakes.
