Subdaily Slow Fault Slip Dynamics Captured by Low‐Frequency Earthquakes

Geodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies evolution to its long-term dynamics. Accompanying seismic low-frequency earthquakes located precisely in time and space provide an opportunity image dynamics at subdaily scales. Here we show that a high-resolution history earthquake fault alone can reproduce geodetic observe be dominated by However, simple linear model cannot accommodate complex present throughout cycle, analysis different phases cycle shows ratio varies as function time. This suggests source region saturates grows moment area. We propose rheological heterogeneities plate boundary associated with do not play significant role rupture process, thus implying their activity incidental driving aseismic slip.
