抄録

The Iwate-Miyagi Nairiku Earthquake of 2008 occurred in an area where no active faults were known to exist. However, after conducting a detailed investigation of this area after the earthquake, we discovered that an active fault actually existed in this area. If this active fault had been identified and if the magnitude of a potential earthquake had been anticipated prior to the actual earthquake, it may have been possible to take adequate precautions that would in turn have led to lesser damage. Therefore, it is extremely important to identify active faults that may generate a major earthquake. The length of the newly discovered active fault was found to be significantly shorter than that of the seismogenic fault;therefore, it was extremely difficult to estimate the magnitude of an earthquake. This is the major issue raised by this earthquake.
