From: Stress transfer outpaces injection-induced aseismic slip and triggers seismicity
(a)–(d) Space–time plots of slip velocity for \(\tau _a = 32.7\) MPa using different injection rates. The 0.01 MPa pore pressure contour is plotted in yellow dashed line. The 0.1 MPa change in Coulomb failure stress \(\Delta CFS\) is plotted in red dashed line. Maximum slip velocity \(V_\text {max}\) is indicated on each plot. Migration speed of the 0.1 MPa \(\Delta CFS\) is indicated in (c) and (d). (e) \(V_{\text {max}}/V_{\text {seismic}}\) and (f) speedup in time to failure versus \(\tau _a/\sigma\) on this asperity for various injection rates. Note that at low injection rate of \(q = 2 \times 10^{-6}\) m/s, the behavior is the same as having no injection.
