The acceleration sensor 2a outputs an earthquake detection signal at a voltage level proportional to the acceleration when a horizontal acceleration is applied when a fabric foundation 6 to be described later rolls due to the occurrence of an earthquake. . For example, if the direction parallel to one of the outer walls and one of the other outer walls arranged at right angles in the plan view of the building 1 is the X direction and the direction parallel to the other outer walls is the Y direction, The applied acceleration is separated into the X direction and the Y direction, and an earthquake detection signal is output at a voltage level proportional to the acceleration in the separated X direction and Y direction.
The acceleration sensor 2a outputs an earthquake detection signal at a voltage level proportional to the acceleration when vertical acceleration is applied when the cloth foundation 6 of the building is pitched due to the occurrence of an earthquake. For example, when the vertical direction is the Z direction, the earthquake detection signal is output at a voltage level proportional to the acceleration in the Z direction applied to the building.
