Comparison of the spatial distribution of the 1968, Hyu'uganada earthquake with source region of a few large event occurred since 1968 event. Rupture fronts estimated from rupture pick time each sub-fault . Source region estimated by our analysis. Solid line D (d1, d2) represent bending of plate, and dotted line E represent transverse discontinuity Slab.

This picture allows us to understand that earthquake rupture terminate at geometrical change.
