- Description
- The 2011 off the Pacific coast of Tohoku, Japan, earthquake caused significant damage to engineering structures, not only due to tsunamis but also due to strong ground motions. In this paper, an extended site effects substitution method was used to estimate strong ground motions at the site of damaged elevated bridges of the Tohoku Shinkansen in Kitakami City, Iwate Prefecture, Japan, for the 2011 main shock,
with the site amplification and phase effects evaluated based on temporary aftershock
observation records at the proximity of the site.
