Excellent summaries of the IHFC history are compiled here:


The following material is taken from the above mentioned references.

The study of the thermal structure of the Earth, generally referred as the geothermics or also as the (terrestrial) heat flow, has a long history. However, the modern geothermics, one of the fundamental geophysical disciplines, is relatively young. The International Heat Flow Commission (IHFC), under which the academic geothermal research on the international scale is organized, was created only in 1963. The IHFC, operating under the International Association of Seismology and Physics of the Earth's Interior (IASPEI), covers a broad scope of geophysical studies and links the activities of other associations of the International Union of Geodesy and Geophysics (IUGG), namely, the International Association of the Physical Sciences of the Ocean (IAPSO), the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI), and the International Association of the Hydrological Sciences (IAHS).
Geothermal research is further related to a number of geological, hydrogeological and geochemical investigations covered by the International Union of Geological Sciences (IUGS), and in their practical applications the heat flow studies are related to the mission of the International Geothermal Association (IGA). Most of the knowledge of the contemporary geothermics was formulated only in the last half of the 20th century. The basic ideas on the thermal structure and thermal history of the Earth, based on routine measurements of borehole temperature on land and measurements of heat flow through the ocean floor, together with determinations of the thermal properties of the rock material were enabled by the rapid development of measurement techniques in the 1950s. Geothermal modeling, the assessments of the deep lithosphere temperature, evaluation of the thermal regimes of geological processes on local, regional and global scales were made possible by the recent advancement of computer techniques.

1963 - The Birth of the IHFC

The year 1963 represented an important milestone in the development of the international co-operation in the geothermal research. At the thirteenth IUGG General Assembly at Berkeley, California, 19-31, August, 1963, Sir Edward Bullard (Figure 1) of Cambridge University, England, called an informal meeting to organize a heat flow committee to promote geothermal research, especially in areas where there were no heat flow measurements. Bullard’s agenda included organizing symposia and field trips, comparing techniques, maintaining a database, and publishing a monograph, and they were well received. Sir Edward said that a committee secretary would be needed to coordinate its activities and asked for nominations from the floor. After a few minutes of silence, Bullard nominated W. H. K. Lee to be the secretary, and his motion was seconded by John Jaeger of Australia. Since there were no other nominations, Lee became the proposed secretary. Sir Edward then instructed Lee to find a deputy secretary who would succeed him three years later. Gene Simmons who was at the IUGG General Assembly kindly accepted the invitation. Bullard would chair the Committee, and Elena Lubimova of the Soviet Union would be the vice-chair. The proposed officers and Committee members would be appointed by three IUGG Associations: Seismology, Volcanology, and Oceanography at the end of the General Assembly.

A few days later, Bullard withdrew as the proposed chairman of the Heat Flow Committee in order to run for the IUGG presidency. He then persuaded Francis Birch, a heat flow pioneer at Harvard University, to be the proposed chair of the Heat Flow Committee. At the end of the IUGG General Assembly, the International Heat Flow Committee (later Commission) was established under the following resolution (IASPEI, 1964): “... that the IASPEI should establish a working group on geothermal problems which should arrange comparisons of the techniques of different experimenters, particularly in the measurement of thermal conductivity, organize a symposium at the next General Assembly, and collect and summarize the observational data. The committee should arrange for adequate liaison with the International Association of Volcanology ...”

The first International Heat Flow Committee consisted of:

  • Francis Birch, chairman
  • Elena A. Lubimova, vice-chairman
  • William H. K. Lee, secretary
  • Gene Simmons, deputy secretary.

Members were: C.J. Banwell, A.E. Beck, T. Boldizar, E.C. Bullard, J.C. Jaeger, A.M. Jessop, M.G. Langseth, C. Lomnitz, V.A. Magnitsky, L. Stegena, S. Uyeda, and R.P. Von Herzen. The International Association of Volcanolgy appointed the following liaison members: G. Facca, J. Healy, J. McNitt, and P. Evrard.

1964 - First Heat Flow Symposium and Monograph

In March 5-6, 1964, F. Birch hosted the first Heat Flow Committee meeting/symposium at Harvard. All the officers and about half of the Committee members attended. About a dozen guest participants also presented their results. Birch appointed a working group, consisting of A. Beck, G. Garland, A. Jessop, M. Langseth, W. Lee, E. Lubimova, and R. P Von Herzen, to work out the details so that the manuscripts of a heat flow monograph could be submitted to Lee as the editor within six months (IUGG, 1964).
The American Geophysical Union (AGU) had started its geophysical monograph series at that time. Jack Jacobs of Canada, who was a member of the AGU Committee overseeing the geophysical monographs persuaded his Committee to approve the publication of the heat flow monograph. Carrying a briefcase-full of manuscripts that had been reviewed and revised, Lee went to the Headquarters of the American Geophysical Union in Washington D.C. in January, 1965. With the timely support of Mr. Waldo E. Smith, the then AGU Executive Director, and Ms Judy Holoviak, the efficient copy editor, the heat flow monograph was published in August 1965 as AGU Geophysical Monograph No. 8, about 10 months after the manuscripts were received.
This monograph is subdivided in nine chapters, well characterizing all aspects covered by the IHFC for the following decades: (1) Historical introduction to terrestrial heat flow (E.C. Bullard), (2) Application of the theory of heat conduction to geothermal measurements (J.C. Jaeger), (3) Techniques of measuring heat flow on land (A.E. Beck), (4) Techniques of measuring heat flow though the ocean floor (M.G. Langseth), (5) On heat transfer through the ocean floor (E.A. Lubimova, R.P. Von Herzen and G.B. Udintsev), (6) Review of heat flow data (W.H.K. Lee and S. Uyeda), (7) Geophysical deduction from observations of heat flow (G.J.F. MacDonald), (8) Physical processes in geothermal areas (J.W. Elder), and (9) Review of geothermal resources (J.R. McNitt).

2003 - 40th Anniversary and Commemorative CD

At the 23rd General Assembly of the International Union of Geodesy and Geophysics at Sapporo, Japan, the International Heat Flow Commission celebrated its 40th anniversary. The celebration party took place at the hotel Royton Sapporo, the venue of the IUGG Assembly, in the evening of July 4, 2003. The party started by an informal reception where about 100 participants met together in a friendly atmosphere. It was followed by short speeches, violin music, dinner, and honoring Seiya Uyeda.

Lee, Sukanta Roy, Seiya Uyeda, Vladimir Cermak, David S. Chapman, Valiya M. Hamza, Ki-iti Horai, and Massimo Verdoya.
