Key Points

This research aims to clarify the elastic properties of the crust in subduction zones, focusing on frictional sliding mechanisms.
Analyzed sedimentary rock characteristics in the Shimanto accretionary complex
Investigated the relationship between temperature and elasticity at depth
Reviewed literature on frictional and velocity weakening properties
Identified velocity weakening as a key factor in frictional slip mechanisms
Found that elastic properties vary significantly with depth and temperature
Demonstrated the complexity in modeling earthquake mechanics due to these elastic variations

Implication

Research assesses elastic properties in seismogenic zones, indicating complexities in earthquake mechanics.
