Session Description Geophysical instruments have detected slow earthquakes without radiation of strong seismic waves since the end of the 20th century. Many anomalies of geodetic deformation were characterized as SSE (slow slip events), and weak seismic signals were characterized as LFE (low-frequency earthquakes), VLFE (very low-frequency earthquakes), and tremors, mainly at subduction plate boundaries such as Alaska, Cascadia, Chile, Costa Rica, Ecuador, Japan, Mexico, and New Zealand. All of them are primarily shear slips. Slow earthquakes obey different scaling laws from regular earthquakes. What causes their difference has been under debate. They might be attributed to friction laws, rheological properties, or fault geometries. Slow earthquakes frequently occur adjacent to source areas of large regular earthquakes. Their mechanical interaction may be a key of understanding generation process of large earthquakes. Slow earthquakes change the stress conditions surrounding the source areas of large earthquakes, or, preslips and afterslips of large earthquakes fluctuate activities of slow earthquakes.

We welcome researchers modeling the generation processes of slow and/or regular earthquakes by data analyses, numerical simulation, or theoretical consideration. Experimental or observational researchers in the fields of seismology, geodesy, geology, and physics, are also welcome to share their views for proper modeling.
