On November 7, 2019, at the invitation of the researcher Shan Xinjian and Assistant Research Fellow Liu Jiao of the State Key Laboratory of Earthquake Dynamics, Professor Alexander L. Strom from the JSC Institute of Hydroelectricity Engineering of Russia made two speeches entitled “Relationships between earthquake magnitude and surface rupture parameters: overview and some problematic issues” and “Study of active faults during engineering investigations of lifeline routes (trunk pipelines, railroads, power lines)” in conference room 204 of our institute.

Professor Strom is the chief expert of the Geodynamics Research Center of the JSC Institute of Hydroelectricity Engineering, anadjunct professoratChang'anUniversity, and a visiting professor at Chengdu University of Technology; he also serves concurrently as an editor for the international journal Landslides. He has long been devoted to research on geological hazards, active faults, neotectonics, paleoearthquakes, and remote sensing applications in earthquake tectonics and engineering geology. As a leading expert on large catastrophic landslides, Professor Strom has led and participated in the geological assessment and demonstration of large projects in the former Soviet Union, Mongolia, India, Sudan, and other countries. He has published many papers in well-known international journals such as Landslides and Geomorphology,and is responsible for writing and editing monographs such as Rockslides and Rock Avalanches of Central Asia, Landslides from Massive Rock Slope Failure, Natural and Artificial Rockslide Dams,etc.

In his first report, Professor Strom focused on his research on the empirical relationship between magnitude and fault surface rupture parameters, based on his collated and compiled database of earthquake parameters for about 400 historical and modern earthquake of 3.5 ≤ Ms ≤ 8.5. These results have been widely used in the earthquake safety evaluation in the Amur region of Russia, the Sakhalin Peninsula, Kyrgyzstan, southern Kazakhstan, and other countries and regions. The second report started with the definition of an active fault, the research purpose, and basic research methods, and focused on the different types of lifeline engineering (highways, railways, power lines, oil pipelines, etc.) in relation to the characteristics of active faults, and the selection of parameters related to active faults. The accuracy of evaluation in the design of trunk pipelines was also described in detail.

Many researchers of our institute and other scholars who attended the report engaged in a heated discussion on the earthquake-resistant design of oil and gas pipelines across faults.

This academic report attracted more than 30 scientific and technical personnel and students to attend; the effect was remarkable, the academic atmosphere was warm, and the participants benefited considerably.
