Abstract

The purpose of this paper is clarify the seismic response characteristics of small irrigation earth dams on the basis of the observation immediately after an earthquake swarm beginning from December 17, 2009 in the region of off the east of Izu peninsula. We performed a two-day earthquake observation simultaneously on two valley-type irrigation dams, placing three sets of three-component microtremor sensors on the crest of the two dams and on the outcropping firm ground, immediately after the beginning of the earthquake swarm. The results of analyses on seven small and micro-earthquke records revealed that the horizontal dynamic response characteristics of the dam crest identical to each other.
