Beijing National Earth Observatory (NEOBJI) is managed by the Institute of Geophysics (IGP),
China Earthquake Administration (CEA), which is an important field arm of IGP and having held aleading role in earthquake and multi-disciplinary geophysical observation in China for many years.
NEOBJI has a long glorious history.
YEAR_1930. The first seismic station in mainland China, which was installed by Chineseseismologists in 1930. After the Wiechert seismograph and Galitzin-Willip seismograph weredeployed, the first seismograph was recorded on Sept.30, 1930.
YEAR_1930 to YEAR_1937. 2427 earthquakes were recorded. Bulletins and observation
reports were published monthly and the data were exchanged with seismological agencies allover the world, which makes NEOBJT as a landmark of the modern seismological observationin China.
YEAR_1957. Renamed as Beijing Observatory, and obtained earthquake waveform data sinceJune.1, 1957, with the installed 513-type mid-strong seismometer. The geomagnetism records
was first obtained in 1957.
YEAR_1982. A 202m-depth cave for geophysical observation was completed with total innerlength of 317.5m.
Year_1982 to Year_2010. Seismometers, a gravimeter, and tilt-meters were installed in thecave, while geo-magnetometers and instruments for water level were installed in the yard anddown in boreholes.
YEAR_1984. Be awarded the “International Earth Observation Centenary” Silver Medal by
IAGA in recognition of the outstanding contribution in Geomagnetic Observation.
FROM_1986. Be a stationof CDSN/GSN, sharing
seismic data with the world.
FROM 1990s. Be aGSETT beta station, and a
CTBTO/IMS auxiliary
station.
FROM 2000. Be a China
National Backbone Field
Station, honored by theMinistry of Science andTechnology of thePeople's Republic of China.
