The Hayward Fault has been assessed in the Uniform California Earthquake Rupture Forecast version 3 (UCERF3) as the second most likely location in California for an earthquake larger than magnitude 6.5 in the next 30 years and runs through the extensively urbanized eastern San Francisco Bay area. We are measuring and modeling near-fault deformation to better understand the fault zone properties and their variations in space and time, using SAR interferometry, Lidar scanning, and GNSS analysis. We use model inversion methods to estimate the accumulation and release of strain on the Hayward Fault to estimate the interseismic coupling at depth and assess off-fault deformation in the zone near the fault. Interseismic deformation on the Hayward Fault is important for understanding earthquake risk in the area as well as other basic processes such as the evolution of faults over longer periods of time.
