2012 Annual Report - Research Reports
From Research Section 5:
This model of creep, movement on the Hayward Fault with no accompanying earthquake, suggests that the creep rate near the surface is faster along the southern section of the fault. At greater depth, the situation is reversed, with higher rates in the north than in the south. Given the fact that most of the Hayward fault has accumulated a deficit of 30%-90% of its long-term slip budget, we estimate that seismic moment for a Mw ~6.3-6.8 has accumulated since the last big event in 1868.
