Is the concept of seismogenic zone still relevant after the 2011 Japan earthquake?
Tohoku is the seismogenic zone, the asperity model explained this small repeating earthquake well. It was said massive earthquake will occur in Nankai Trough. As their expectation was wrong, [Kato and Yoshida, 2011],[Hori and Miyazaki, 2011] created new models.
ref Notice japanese source.

Here is new model of Sansoken(National institute of advanced industrial science and technology). In this model, asperity model is still alive.
