absence of Mach surface wave characteristics. Compared with the EAF, the NF features denser seismic activity in recent decades, suggesting that it was more favorable for rupture nucleation. The EAF segments where the largest coseismic slip occurred have been relatively quiescent since the late 1800s. But the slip is much larger than the long-term accumulation during this period, being attributed to ≥900 year supercycle. The EAF geometry is similar to the San Andreas Fault (SAF) and San Jacinto Fault (SJF). Considering high slip rates and the lack of large earthquakes on their southern segments since 1857, an M8 earthquake could potentially occur there.
