I reviewed procedures in Japan, called Recipes, for predicting strong ground motions, and categorized them into three groups:
First-generation Recipe: the original Recipe proposed by Irikura et al. (1999), based on the physics of multiple circular crack models. The ruptured regions are buried under the ground surface.
Second-generation Recipe: the revised Recipe proposed by Irikura et al. (2002), based on the physics of the asperity model. The ruptured regions are treated to be buried under the ground surface.
Third-generation Recipe: the extended Recipe proposed by Dan et al. (2018), based on the physics of the asperity model. The fault rupture reaches the ground surface or the sea bottom.
The first- and second-generation Recipes predict strong ground motions, while the third-generation Recipe, under development still now, also predicts permanent displacements near the faults and tsumanis.
