Scope
|
Subduction plate boundary is the place where fluid goes down into the deep interior earth and flows back to the surface. The fluid generation and behavior might be causal relationship with outer-rise earthquakes, tsunamigenic slips, shallow VLF earthquakes under the outer-trench slope, great earthquakes in seismogenic zone, deep VLF events, and intra-slab earthquakes in the mantle. This session focuses on the relationship between the fluid behavior and seismogenesis from the shallow to deep subduction zone, and tries a comprehensive understanding.
