It's actually impossible to know for certain how much and what size of land you're destabilizing. Duration of expected destabilization is also varying I guess and at least 1 year.
> "Exponential relationship between the total number of earthquakes and the number of wells in the Texas during the study period
1998–2018 with correlation R2=0.726."
It's not fracking itself but actually wastewater injection has a bigger influence in triggering bigger earthquakes according to what I've read. Moreover, it's also known that dams have a significant impact:
> "The devastating earthquake in Sichuan, which took at least 69,000 lives in May 2008, may have been unleashed by the huge Zipingpu Dam. New scientific evidence suggests that the filling of the Zipingpu reservoir may have activated a dormant fault line near the dam site."
Shallow faults are definitely activated. Probability of deep faults activated through full destabilization of a region? Unknown for now.
Oklahoma, 2012 seismic sequence in Emilia (Italy), Sichuan Basin are already examples that triggered protests and call for investigations: https://en.wikipedia.org/wiki/2012_Northern_Italy_earthquake...

An example study for US that states the activity is exponantially linked to fracking sites: https://par.nsf.gov/servlets/purl/10233410

In the tragic earthquakes of 2023 in Turkey, this relationship was again discussed in mainstream media: https://en.wikipedia.org/wiki/2023_Turkey%E2%80%93Syria_eart...
