The Institute of Earthquake Forecasting (IEF) of the China Earthquake Administration (CEA) is focusing on research of the theory, methodology, techniques, and application countermeasures of earthquake forecast based on geology, geodesy, geochemistry, space electro-magnetism, remote sensing, and seismology. For more than half a century, China has carried out a wealth of seismic scientific investigations, and more than 200 case studies of M=5.0 earthquakes have been summarized. Amonth with, The IEF CEA is the authority for leading comprehensive investigations and has been responsible for organizing the domestic seismic scientific investigations since 2019, including 2019 Changning (M 6.0) earthquake, 2020 Jiashi (M 6.4) earthquake, and Yutian (M 6.4) earthquake, 2021 Maduo (M 7.4) earthquake and Luxian (M 6.0) earthquake, 2022 Menyuan (M 6.9) earthquake and Lushan (M 6.1) earthquake, 2023 Jishishan (M 6.2) earthquake, 2024 Wushi (M 7.1) earthquake, and other destructive earthquakes.
