了解地震滑动的演化，能够限制断层的地震预算，并提供深入了解蠕变的动力学。反演从干涉合成孔径雷达获得的中央圣安德烈亚斯断层沿着测量的地表变形的时间序列，结合重复地震的测量，我们约束蠕变的时空分布在1992-2010年。我们确定了一类新的中期蠕变率的变化，演变超过十年尺度，释放应力的加速区和加载相邻的减速补丁。我们进一步表明，在短期内（
Understanding the evolution of aseismic slip enables constraining the fault's seismic budget and provides insight into dynamics of creep. Inverting the time series of surface deformation measured along the Central San Andreas Fault obtained from interferometric synthetic aperture radar in combination with measurements of repeating earthquakes, we constrain the spatiotemporal distribution of creep during 1992-2010. We identify a new class of intermediate-term creep rate variations that evolve over decadal scale, releasing stress on the accelerating zone and loading adjacent decelerating patches. We further show that in short-term (
