Abstract
The clustering of earthquakes in time on the same fault affects the rate and pattern of interseismic deformation. We develop a simple analytic viscoelastic model of the surface velocity field through a clustered earthquake cycle by superposing the velocities of individual earthquake cycles of constant period but varying phase. Velocity profiles prior to and after an earthquake show a wider range of behavior than they do for earthquake cycles with constant repeat times. These new types of behavior provide possible explanations for discrepancies between geologic estimates of long‐term fault slip rates and slip rate estimates from geodetic data.
