We evaluated the fault parameters of asperity models for inland earthquakes caused by long strike-slip faults based on the procedure proposed by Dan et al. (2011)1), and simulated strong ground motions by these asperity models. The models had a constant dynamic stress drop averaged over the entire fault of 34 bars and that on the asperities of 122 bars. We presented five models with the fault length of 25 km, 50 km, 100 km, 200 km, and 400 km, and simulated strong ground motions from the three models with the fault length of 50 km, 100 km, and 400 km. The simulated motions were consistent with the records of the 2000 Tottori-Ken Seibu, Japan, earthquake, and the 2002 Denali, Alaska, earthquake as well as the attenuation model of peak accelerations and peak velocities proposed by Si and Midorikawa (1999)2). These results verified the procedure proposed by Dan et al. (2011)1) for evaluating fault parameters of asperity models.
