Research Abstract

We developed methods for the real-time determination of the location of fault area of mega thrust events such as Tonankai, Nankai and Tokai earthquake. It is found that shaking intensities of P waves saturate at the focal area of large earthquakes. We showed that shaking intensity data can locate fault area of Tokachi and the above three simulated earthquakes. Stability of the solution for the fault area suggests that present method is effective for the real-time determination of earthquake information for mega thrust events.
