000019499 520__ $$2eng$$aWe simulated the strong motions at Onagawa, Japan, during the 2011 off Miyagi intra-slab earthquake (Mw7.1) by the empirical Green’s function method. We used some different elemental earthquakes in order to investigate the applicability of this method for the intra-slab earthquakes. At first, we established the asperity model based on the previous study. Then, the elemental earthquakes were selected under some criteria. Finally, we carried out the strong motion simulations for three models: using only one elemental earthquake (Model 1), using three elemental earthquakes which were arranged according to the relationship between their source locations and the subfaults of the target large fault (Model 2), and using three elemental earthquakes which were arranged randomly (Model 3). For the model 1, the variation of the simulated strong motions to the observed strong motion was large. On the other hand, for the models 2 and 3, the variation of the simulated strong motions to the observed strong motion was smaller than that of the model 1 because the characteristics of each elemental earthquake were averaged. This conclusion agrees with that in Dan et al. (1990) for a crustal earthquake.
