To provide an acceleration seismographic apparatus which is provided with high reliability, installation easiness and transportation easiness.
In an acceleration seismographic apparatus 1, three acceleration seismographic parts 10, 20, 30 and a computing and output part 3 are housed inside an enclosure 2, At this time, when at least two acceleration seismographic parts out of the acceleration seismographic parts 10, 20, 30 detect a tremor, the computing and output part 3 transmits the detection of the tremor to the outside. In addition, the computing and output part 3 may be housed inside a separate enclosure, and the enclosure and the enclosure 3 may be integrated by using a rigid coupling. In this case, a signal wire is passed through the rigid coupling, and the acceleration seismographic parts 10, 20, 30 are connected to the computing and output part 3.
