Invited by State Key Laboratory of Geodesy and Earth`s Dynamics (SKLGED), professor Yue Zhongqi from The University of Hong Kong visited Institute of Geodesy and Geophysics(IGG) and gave an academic report “Second hypotheses on volcanic origin and its mechanism” on April 13. Academician Xu Houze, researcher Yan Haoming and more than 30 scientific research personnels attended the meeting. The workshop was hosted by researcher Sun Heping.

The report began with a brief introduction of traditional idea of volcanic that generated by mantle magma. This assumption assumes that all volcanoes was formed by high temperature hydrothermal magma shift from the mantle. Then he showed his investigation and observation of volcanoes around the world, taking the volcanoes and natural gas fields in the Midwest, Japan, Indonesia and Northeast China as an example. Professor Yue proposed second hypotheses on volcanic origin was methane gas and explained the model which can replace traditional volcanic origin and can better explain all the phenomena of volcanoes. All the participants conducted a systematic and in-depth discussion at the end of meeting.

Professor Yue is mainly engaged in Geotechnical Engineering Practice. For more than 30 years, he has done a lot of engineering and research work, and has made a series of original discoveries, methods, laws and theories. He obtained master degree in geodynamics, Peking University, 1986 and received his Ph.D. in geotechnical engineering from Carleton University, Canada in 1992.
