The coastal acoustic tomography systems (CATSs) were set up at the edge of the breakwater on both the Honshu and Shikoku sides of Akinada, located at the central part of the Seto Inland Sea. Then the reciprocal sound transmission experiment was performed every 5-10 minutes between two CATSs and path-averaged currents were calculated with the accuracy of 1 cm/s from the differential travel time data. This method is applicable to the measurement of weak tidal waves because the current measurement accuracy of 1 cm/s corresponds to the sea surface height measurement accuracy of 2 cm. Tidal waves were measured instead of tsunamis since there were no tsunami generation during the project. It is concluded that this method is also applicable to tsunamis which is the same surface gravity waves as the tidal waves.

沿海声断层扫描系统（CATSS）是在Akinaada的Honshu和Shikoku侧的防波堤边缘建立的，位于Seto Inland Sea的中部。然后，在两只猫之间进行每5-10分钟进行一次相互传播实验，并以差分旅行时间数据的精度为1 cm/s计算路径平均电流。该方法适用于弱潮汐的测量，因为当前的测量精度为1 cm/s，对应于2 cm的海面高度测量精度。由于该项目期间没有海啸，因此测量了潮汐而不是海啸。可以得出结论，该方法也适用于与潮汐相同的表面重力波的海啸。
