Question

In Oklahoma, why do injections wells cause earthquakes, and what type of wells are these?

Answer 1

Answer:

Due to fluid flowing down to the fracture

Explanation:

Many scientist and policy maker discovered that depth-volume joint impacts are critical, and the amount of INJECTED MATERIAL  becomes more important  at point where surface of  sedimentary rocks contact crystalline strata rocks and it is capable to cause earthquakes — The main reason behind this massive earthquake is the percolation through deep well which allow easy access to liquid to flow down to fracture that are more susceptible to earthquake.
