Back in the 1940's and earlier you could rebuild the hydraulic shocks in many vehicles but since then they cannot be rebuilt, just replace with a new one.

a hydraulic fluid pushes parts to do what you want them to
Movement of high pressure magma underground typically occurs before a volcanic eruption. This magma is under such a high pressure that it can cause hydraulic fracturing of the surrounding rocks and even bulging of the crust. Both these events will release seismic waves (cause earthquakes). All these data help geologists predict that an eruption is about to occur.
The hydraulic lift was invented by Leon Edoux.
I know Vermont just signed a bill banning hydraulic Fracturing. The states where Hydraulic Fracturing is allowed are all doing very well though. Natural Gas drilling brings in lots of money and creates jobs for Americans. If a well is dug responsibly, there should not be any effect on the environment whatsoever, so a state banning hydraulic fracturing seems a little excessive to me.
The controversial around hydraulic fracturing is the contamination of the water that we consume.
yes hydraulic fracturing of natural gas does effect seismic activity.
Yes.
Hydraulic fracturing was created to allow otherwise inaccessible oil and natural gas reserves to be tapped and harvested for human use.

Hydraulic fracturing, also called fracking, hydrofracking, and hydrofracturing, is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid.
Hydraulic fracturing breaks open the rock that contains oil or gas deposits and holds this fracture open with sand or proppant so that the oil or gas is able to flow into the wellbore for surface extraction. Without hydraulic fracturing oil and natural gas prices in this country would be astronomical.
The French use either fracking or fracturation(fracturing).See the related link.
Hydraulic Fracturing, commonly known as 'fracking'.
HYDRAULIC FRACTURING HYDRAULIC FRACTURING TECHNIQUESThe vast majority of the nation's newly drilled natural gaswells do not produce gas at sufficient rates to make thewell economical. Hydraulic fracturing is a technique usedto allow natural gas and crude oil to move more freelyfrom the rock pores where it is trapped to a producingwell so it can be brought to the surface at higher rates.Hydraulic fracturing technology was developed in the late1940s and has been continuously improved upon sincethat timeHYDRAULIC FRACTURING TECHNIQUESThe vast majority of the nation's newly drilled natural gaswells do not produce gas at sufficient rates to make thewell economical.

The water can fill the crack and exert pressure on the surrounding rock walls, potentially widening the crack over time through hydraulic action and freeze-thaw cycles. This process is known as hydraulic fracturing or water-induced fracturing.
