Slow earthquakes releases significant amount of stress form major plate
boundary faults worldwide. In addition, there is ample evidence that
slow earthquakes interacts with their regular counterparts and affect
the overall fault dynamics. Yet, characterizing their tectonic behavior
remains challenging due to the nature of deformation and complex seismic
radiation, i.e. tremor. Beam backprojection technique images slow
earthquakes in high resolution by detecting and locating seismic tremor
using well-designed mini seismic arrays. I use this technique in
Cascadia and Alaska subduction zone, and San Andreas Fault to show the
evolution of slip during slow earthquakes as expressed by seismic
tremor. Analyses of the intricate details of the spatiotemporal
distribution of tremor and its migration patterns are providing new
insights into the physics driving slow earthquakes and fault mechanics.
