Research Abstract

It is important to estimate seismic slip distribution of large earthquakes in order to understand seismic source processes and reduce earthquake disaster. The data from marine terraces seem to be useful for estimation of slip distribution of plate boundary events at subduction zones. This study shows how to divide the coseismic, interseismic and permanent displacements using our earthquake cycle model with viscoelastic media.
Our earthquake cycle model can estimate the permanent displacements by the steady state subduction. The model also reveals that the difference between the data whose phases in the earthquake cycle are the same (for example, data of all marine terraces are in the phase of just before event) depends only on the permanent displacements. This means that we can estimate the permanent displacements if we have two or more marine terrace data whose ages are different. Since our cycle model can estimate stress relaxation in the asthenosphere, we can divide the coseismic, intnrseismic and permanent displacements into one another. From the coseismic and interseismic displacements, we can estimate slip distribution of the event.
Using the above method, we estimate slip distributions of the 1703 Genroku Earthquake. The estimated slip distribution shows more than 20m slip beneath the south end of Bolo Peninsula. The estimated permanent uplift rates are up to 3mm/yr.
