Effects of the shallow subsurface structures on the ground motion characteristics in Kumamoto Plain north-south survey line


Abstract
We have been observing earthquake ground motion in a north-south line in the Kumamoto Plain, immediately after the 2016 Kumamoto earthquake. We also performed array microtremors observations at the each site around seismic stations. In order to evaluate the influence of earthquake ground motion from surface structure in the Kumamoto plain, we estimated the local site effects by both earthquake data and array microtremor observation data.
