For the record... you said to learn more about Geothermal Power. So I did.
Isn't it odd that last time we talked you balked at my responses saying I didn't have any links, any evidence. Now I have them. Yet you are mocking the evidence without responding to it. I'm shocked... so very shocked. At least you are on Nuclear as the competitor instead of BigOil. Maybe you did learn something after all.
Yes Geothermal power does cause earthquakes. This is natural. All geothermal systems cause earthquakes, whether natural or artificial.
In a natural system, earthquake are normally very small, imperceptible to humans. If a system like this is tapped for power, adding water to it, normally isn't an issue because it's a naturally existing system. You just provide it with more fuel.
However, with the Swiss power plant, this was not the case. Hot Dry Rock systems, is where you find a heat source with no existing geothermal system. As such, you must create a geothermal system by pumping water down to the rock, then using high pressure and sometimes acidic chemicals, you actually break up the rock formations, fracturing it, and making it permeable.
The rock layer must be broken up in order for water to flow through and absorb the heat. Of course... doing that to rock layers so deep in the ground... obviously causes earthquakes... and large ones. The largest recorded so far is 4.5.
This is why I only support geothermal power in existing systems, not Hot Dry Rock artificial systems. Of course that limits geo-power to 1/4 of the possible suitable locations.
Again, the fact geothermal power plants cause earthquakes is well established. Take a look at the list I provided on the second post. It's fairly long.
