The 2011 off the Pacific coast of Tohoku, Japan, earthquake caused serious damage to engineering structures, not only due to tsunamis but also due to strong ground motions. The serious damage of Naruse River dike due to the 2011 main shock is reported. In this study, we carried out the microtremor measurement, and calculated microtremor H/V spectral ratio in 13 seismic observation stations around the Naruse River basin. Furthermore, we computed site amplification factors in the seismic observation stations based on the temporary aftershock observation records. The calculated H/V spectral ratio and site amplification factors will contribute to the strong motion estimation of the damaged Naruse River basin and clarification of damage mechanisms in the future study.
