Invited by State Key Laboratory of Geodesy and Earth`s Dynamics (SKLGED), professor Clifford Thurber from University of Wisconsin-Madison visited Institute of Geodesy and Geophysics(IGG) and gave an academic reports in title “Active-Source Seismic Tomography at Brady Geothermal Field, Nevada, with Dense Nodal and Fiber-Optic Seismic Arrays” on Oct 20.

In his report, professor Clifford Thurber firstly introduced the research background of the Brady Hot spring pore structure 3D imaging demonstration project in Nevada, the United States of America, the seismic array layout and data acquisition and other related information. Based on the seismic velocity structure imaging and preliminary results of the active and passive source signals, the new distributed optical fiber acoustic sensor Quantitative comparison of records with records of conventional seismographs. After the report, audiences conducted a discussion with professor Clifford Thurber on related issues in depth.

Professor Clifford Thurber is mainly engaged in seismic tomography. The object of study includes subduction zones, fault zones, volcanoes and geothermal fields. He is also devoted to using the seismology and geodesy observations to jointly study seismic source parameters. He has published more than 140 academic papers and funded more than 70 projects such as DOE, DOD, NSF and USGS. In 2010, he was selected as AGU Fellow and in 2012 he won the UW-Madison Vilas Distinguished Achievement Award.
