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.
