    • A terrestrial change prediction apparatus including an indicator having a fixing member made of a nonmagnetic material and a plurality of magnetic bodies each having an N-pole end and an S-pole end and fixedly secured to the fixing member with the same magnetic polarity ends facing to each other so that a magnetic repulsive force is produced therebetween. The indicator is rotatably supported such that the magnetic bodies normally orient in a substantially constant direction. Before a terrestrial change such as an earthquake occurs, the indicator displaces. By measuring the displacement of the indicator, an occurrence of a terrestrial change can be predected.
    • 一种地面变化预测装置,包括具有由非磁性材料制成的固定构件的指示器和具有N极端和S极端的多个磁体,并且固定地固定到具有相同磁极性的固定构件 彼此之间产生磁性排斥力。 指示器被可旋转地支撑,使得磁体通常以基本恒定的方向定向。 在发生地震等地震发生之前,指标会发生变化。 通过测量指标的位移,可以预测地面变化的发生。
