With seismological observations and the development of the prototype seismometric apparatus as its main functions, this observatory on Mt. Abuyama in Osaka Prefecture was opened in October 1930 with assistance from Hara Fund.

Registered as an international seismological observation station, the observatory provides important data concerning the nature of earthquakes and the propagation of seismic waves, and makes comprehensive studies on problems of world-wide seismic activity as well as of the earth's interior.

The observatory is equipped with five kinds of instruments for world-wide observations, and two kinds of instruments to enable functioning as a substation of microearthquake observation. Some of high sensitivity, together with sensors for ground tilt and strain, are set up in a deep vault excavated in 1971 to avoid background noises.

The Seismological Bulletin, ABUYAMA has been published semiannually since 1952, listing the results of main observations.
