| Research Abstract |
Distributions and historical changes of active faults in the area off Tokai and Kumano were investigated by seismic reflection survey. Dense seismic survey off Kumano revealed three lines of ENE-WSW trending blind faults. Relative uplift of the northwestern region was dominant and regional uplift of basin center is prominent in recent age. Studies of topography and previously obtained seismic survey data indicate that reverse faulting with dextral strike slip has been active in the area off Tokai and Enshu for a long period.
