Kinda works like this. . .
How much money we making?
How much damage will we make on an x.x quake?
Will we have to pay for that damage?

Profit!!!
Fuck Yea!

It doesn't, actually, because there's no way to predict the quakes. But they do optimization for the maximum amount of money. It's actually quite interesting, but kinda morbid too. A simple version of that kind of math would be the ford pinto (I think that's the name of it? The one that would explode because of where they stuck the gas tank).

Yea, the math is pretty interesting if you don't happen to own a property that is damaged by the work.
They also do the math on things like floods, storms and so on.
A money lender will do the RA (risk assessment) to make sure they come out on top. The amazing thing is that the assessment is long reaching.
The may have data for floods in an area. They can use that data to evaluate the risk to their investment but will not disclose the data to the person taking that risk by borrowing money.
They know there is a 17% chance of a flood in the next 50 years but the mortgage will be paid in 25 so this is an acceptable risk.

Hydraulic fracturing injects millions of gallons of water into oil and gas containing geologic formations deep underground.

Scientific and government research indicates that fracking can cause earthquakes in two ways:

Primarily, during the fracking process Earthquakes were caused by fluid injection during hydraulic fracturing in proximity to pre-existing faults. Secondarily, via the disposal of fracking wastewater via underground injection.

Our report Shaky Ground explores the risks of fracking triggered earthquakes in California. And increased earthquake activity in shale plays with active injection wells, like Texas, Oklahoma and Ohio show the risks are real.

Don't bold that shit, man. It's obnoxious.

Why did you make the whole thing bold? May as well have wrote in all caps.

The earthquake in question is about 30 days old 8/17/15 source USGS. You have the cascadia subduction zone of the coast of B .C . One of the more dangerous faults in North America. It's not a real stretch of the imagination to say that, this article is full of shit and the earthquake was a natural occurrence

Though the connection has not yet been proven, the quake’s epicentre was just 3 kilometres from Progress Energy’s fracking site

It was probably caused by fracking but let's withhold judgement until a connection has been proven. That's the only logical way to proceed.

Ok, something I don't get. My hometown has been Fracking for 50ish years for natural gas. What's different about Oil Fracking that "Causes" earthquakes?

ELI5 please, My work day is about to speed up and won't have read a wall of text.

It shouldn't matter whether they are fracking an oil or natural gas well. What does matter is how seismically active the area is, especially at the depth they injecting. Think of fracking as a catalyst for earthquakes, not a sole cause. It can't cause earthquakes in seismically inactive areas but can lower the threshold for an event in active areas. This is why earthquakes caused by fracking are generally lower magnitude. These earthquakes are triggered prematurely, before the amount of energy needed for a naturally-occurring earthquake is built up. Source: Am a wellsite geologist.

I think the only difference is the fracking fluid and rocks involved, I think, and I could be wrong here, that oil and gas that is being fracked are in two separate types of rock as in one kind of rock might contain the natural gas you're after and require a different fluid mixture to fracture it in the most appropriate way (big cracks or small ones) and rock that has oil is contained in a different kind of rock requiring another fluid mix.
