Abstract

We performed a field survey of damage to wooden houses, tombstone overturning, and microtremor measurements within the near-source area of the 2007 Noto Hanto earthquake. Based on results of the field investigation, peak ground velocity (PGV) and the seismic response of wooden houses during the main shock are estimated in the source region. From the tombstone data, we estimated PGV values over 80-100 cm/s within the area. The maximum values of building drift evaluated are consistent with the damage statistics in the area, which could mainly be controlled by structural performance and strong ground motion amplified due to S-wave velocity profile and soil nonlinearity, i.e., local site effects.
