Description

The Earthquake Research Council issued a long-term evaluation of earthquakes along the Nankai Trough in May, 2013. One of main points of this evaluation is that there is a 60–70% chance of the occurrence of earthquakes during the next 30 years. Several critical comments were presented before and after its announcement, especially on the adoption of the Time- Predictable model to obtain the interval between the last and impending earthquakes using water depths in the Kubono Family documents. We examined old documents including the Kubono Family documents and found several drawbacks. We confirmed that there is a lack of information that are essential for the evaluation of accuracy of measured depths, and construction works had been made almost every year since the opening of the port. Taking the information in available documents and results of recent tidal observations into account, the uplift during the 1707 Hoei earthquake may range between 1.4 m and 2.4 m. Therefore, the society should recognize this large uncertainty and reexamine the way to make use of this information.
