摘要： PROBLEM TO BE SOLVED: To obtain a buoy for measuring tsunami which can obtain necessary characteristics, by improving the degree of freedom for designing the kinetic characteristics of its wave height detecting section.
SOLUTION: A buoy for detecting tsunami is provided with a wave height detecting section A which detects the fluctuation of wave heights, an equipment and material mounting section B which is provided separately from the detecting section A and on which the equipment and materials required for detecting wave heights are mounted, and a connecting section C which is connected to the mounting section B while the section C supports the detecting section A in a state where the detecting section A can be moved in the vertical direction. Since the wave height detecting section A and equipment and material mounting section B are separated from each other and the movement of the detecting section A is not limited by the mounting section B, the degree of freedom for designing the kinetic characteristics of the detecting section A is improved and a buoy having necessary characteristics can be constructed. In addition, the accuracy and service life (operating hour) of the buoy can be improved, because the size of the mounting section B can be increased while the detecting section A is maintained in the optimum shape.

摘要： PROBLEM TO BE SOLVED: To provide a buoy for measuring tsunami which can be improved in tsunami detecting ability without receiving any influence from waves.
SOLUTION: In a buoy for measuring tsunami, a horizontal fin 23 is attached to the upper surface of a balance weight 22 fixed to the lower end (underwater) of a bar-like buoy main body 21 having buoyancy. Since the horizontal fin 23 functions as a resistance plate that stabilizes the buoy main body 21 in the vertical direction against ordinary waves, the influence of the ordinary waves on the main body 21 can be minimized. Since the fin 23 also functions as a detecting plate for efficiently grasping the movement of a water mass at a deeper portion of the bottom face of the main body 21 while having a certain degree of cross-sectional area against tsunami, the buoy can more easily grasp the wave height of tsunami and wave height detecting ability of the buoy for tsunami can be improved.

摘要翻译：要解决的问题：提供海啸测量浮标，可以在不受波浪影响的情况下提高海啸探测能力。解决方案：在用于测量海啸的浮标中，水平翼片23附接到固定到具有浮力的棒状浮标主体21的下端（水下）的平衡块22的上表面。由于水平翼片23用作使普通波浪在垂直方向上稳定浮体主体21的电阻板，因此能够使普通波对主体21的影响最小化。由于翅片23还用作检测板，用于有效地抓住主体21的底面的较深部分处的水体的移动，同时具有与海啸相反的一定程度的横截面积，所以浮标可以更容易地掌握海啸波浪高度，提高海啸浮标波高检测能力。
