In order to consider the simple method of seismic diagnosis of conventional Wooden House using of microtremor measurements, we investigated 28 two-storied houses.By this investigation, we proposed the formula composed of the natural frequency of microtremor measurements, and the joint reduction coefficient determined by building year.This formula reveals a correlation with the evaluation value of seismic diagnosis.

After 2016 Kumamoto Earthquake, we investigated 80 two-storied damaged houses of light-gauge steel structure by microtremor measurement and visual check. We analyzed the relationship of natural frequency of the houses by microtremor measurement and average displacement response spectrum (0.2 - 0.3 seconds) of construction area. As a result, natural frequency of the houses decrease as the displacement response spectrum increase.
