Based on the M 5.7 aftershocks thus far, there is a 3% chance that it could trigger a magnitude-6.5 or larger shock in the next year. The M 5.7 also brought a portion of the Marmara Fault significantly closer to failure.
The Magnitude 7.1 earthquake abruptly halted aftershocks on the M 6.4 cross fault. It also produced a far-flung aftershock sequence that touched the San Andreas, but refused to cross the Garlock Fault.
The 50-km-long rupture has triggered widely dispersed aftershocks. However, almost none of these struck on the faults that the M 7.1 brought closer to failure: The major Garlock Fault; or the Blackwater, Panamint Valley, or Sierra Nevada Faults.
