Chronology of the most important milestones
Emil Wiechert moves from Königsberg to Göttingen. He succeeds in constructing seismographs to deliver the first scientifically valuable recordings for exploring the Earth’s interior.
Wiechert is appointed as associate professor on 28 January and, in February, Director of the Geomagnetic Institute, which is renamed to the Institute of Geophysics with corresponding competencies by decree of 2 July. It is the world’s first institute to work in this field. In the first five decades, the main focus of work is seismology.
In February, the first earthquakes are measured at the observatory using pendulums and light pointers. In summer, further instrumental equipment is developed in the cellar of the observatory; Wilhelm Schlüter develops what he calls a klinograph.
The Institute of Geophysics occupies the new building on the Hainberg hill.
The Old Earthquake Vault is completed and put into operation right away. At the end of the year, the construction of the new institute can be regarded as largely completed.
The Göttingen-based companies Bartels and Spindler & Hoyer play a major role in building the seismographs.
The continuous seismic recordings with the astatic horizontal seismograph are started in January.
Start of recordings with the vertical seismograph; the 17-tonne pendulum is also gradually introduced during that time; the Earthquake Station in Göttingen becomes one of the main stations in the international network for seismological research; Wiechert is appointed to the Chair of Geophysics as full professor.
By 1906, astatic horizontal seismographs by Wiechert are already used outside Göttingen in: Leipzig, Potsdam, Strasbourg, Jena, Hamburg, Uppsala and Samoa. April: full recording of the P, S and surface waves of the San Francisco earthquake; following the Loma Prieta earthquake of 1989 in the same region, the data of the Göttingen station allows a direct comparison of the two quakes.
Additional stations are set up in Clausthal, Heligoland and Tsingtau (China); active experiments with the so-called “Mintrop ball” are started in the same year, marking the beginning of the seismic exploration of near-surface geological layers.
Seismological research in Göttingen makes major progress in both seismogram evaluation and theory, based on the high-quality data delivered by the Wiechert seismographs.
Fundamental scientific work on seismology published at that time relates to: seismic attenuation (Angenheister), method for earthquake location (Geiger method), creation of earth models (Wiechert, Geiger, Gutenberg), calculation of amplitude ratios at boundaries (Zoeppritz equations), first reliable proof of the boundary between the Earth’s mantle and crust at 2,900 m depth (Gutenberg), microseismics (Gutenberg), head waves (Mintrop wave), inverse method for exploring the physical properties of the Earth’s interior based on the travel times of seismic waves measured on the Earth’s surface (Wiechert-Herglotz method).
Mintrop establishes the company Seismos, searching predominantly for crude oil reservoirs on a global scale.
The earthquake that destroyed Tokyo is fully recorded on 1 September 1923.
After Wiechert’s death, Gustav Angenheister takes over as the institute’s director. The main focus of work is the study of the seismic surface waves and the survey of the underground for mining and construction purposes.
The earthquake station in Heligoland is destroyed by bombs.
Angenheister dies and J. Bartels becomes his successor. Under his direction, geomagnetism – in connection with the emerging space research – becomes the main field of work.
The Earthquake Station Göttingen records the explosion that was to blow up bunkers in Heligoland.
Bartels dies and M. Siebert takes over his position, initially on an interim basis, becoming full professor in 1968. The fields of research established under Bartels’ direction are continued and expanded, among them electromagnetic deep sounding by U. Schmucker from 1974.
Recording of all major nuclear explosions
Ulrich Christensen becomes the institute’s new director. Besides his main fields of research (geodynamic models), seismology becomes a new focus. Michael Weber (today at the German Research Centre for Geosciences in Potsdam) comes to Göttingen. The institute leads the “Eifel Plume Project”.

Christensen moves on to the MPI for Aeronomy, Katlenburg-Lindau, which operates today as the MPI for Solar System Research (MPS) in Göttingen. This position has been vacant since then.
100 years of recording the stronger worldwide seismicity and the weaker regional seismicity
Seismological research is no longer carried out in Göttingen. The 100 years of operation of the Wiechert Earthquake Station continues (for now).
16/06/2005: In view of the institute’s recent relocation to the northern area, the current director of the Institute of Geophysics, Prof. Karsten Bahr http://www.physik.uni-goettingen.de/verwaltung/members/Bahr.Karsten.html, orders that the operation of the Earthquake Station be discontinued with immediate effect. Despite some difficulties, the association (Wiechert’sche Erdbebenwarte Göttingen e.V.) and the institute’s staff manage to put the instruments into operation again after a few weeks.
Mid-June 2005: The Institute of Geophysics moves to the physics campus in the northern part of the University of Göttingen. The site is offered for sale by the State of Lower Saxony.
12/08/2005: The Earthquake Station and the scaffolding with the Mintrop ball pass into the ownership of the association “Wiechert’sche Erdbebenwarte Göttingen e.V.”. The Gaußhaus remains the university’s property and is maintained by the association “Wiechert’sche Erdbebenwarte Göttingen e.V.”. The purchase also comprises about half of the site of the former Institute of Geophysics.
