| 内容記述 | The Iwate Miyagi Nairiku earthquake in 2008 caused many dameges to agricultural facilities. The hypocentral region of this earthquake was shallow and the earthquake acceleration was high, especially in vertical direction around the epicenter. But structural damages were relatively low to the large acceleration, because the velocity caused by the earthquake was not so high to the acceleration for the superior high frequency components in the earthquake wave form. Therefore, full or half structural damaged houses were only about 0.2% (162 houses) of the whole number in Oushu city (Iwate prefecture) and Kurihara city (Miyagi prefecture) with an intensity of 6 plus on the Japanese seven-stage seismic scale. Also, structural damages of agricultural facilities were few and most of the facilities damages were indirectly caused by slope collapse, land slide, land subsidence, surface crack. These damages were remarkable in old irrigation channels, tunnels on riverside steep slopes. This situation of low structual damages was almost fit to the structural large damage standard from the maximum acceleration ,velocity for an earthquake proposed by Kawase in 1998. Our investigation results supported this standard also in old agricultural facilities, although the maximum velocity for the earthquake was near the lower limit of the structural large damage. But this standard is not able to cover geological damages and indirect structural damages caused by geological damages like slope collapse, land slide, subsidence, and so on. Therefore, it is important for risk analysis that geological and geographycal risk assessment should be considered as well as assessments from structural fatigue, earthquake acceleration, earthquake velocity. |
