The 2016 Mw5.1 Fairview, Oklahoma earthquakes: Evidence for long-range poroelastic triggering at >40 km from fluid disposal wells

- A fluid injection field induced moderate earthquakes as far away as 40 km.
- Poroelastic solid stresses are larger than fluid pressures at such large distances.
- Densely spaced wells form a coherent source extending the reach of poroelasticity.
- Resulting Coulomb-stress-changes are comparable to static triggering stresses.
