[SSS04-P31] Shallow Slow Slip Event Off the Kii Peninsula in April 2016, Japan
Keywords:SSE, Slow earthquake, Low frequency earthquake
In off the Kii Peninsula, VLF and Low Frequency Earthquake has been often observed, but SSE had not been observed by geodetic method. The slip deficit rate of this SSE source region is about 3 cm / year (Yokota et al., 2016), and the plate convergence rate is 5.0 to 6.5 cm / year (Heki and Miyazaki, 2001). Therefore, in addition to this case, there is a possibility that SSE frequently occurred in this region.
