In recent years, many earthquakes of magnitude 6.0 and above have taken place in Xinjiang (2020 Ms6.4 Jiashi), Qinghai (2022 Ms6.9 Menyuan), and Sichuan (2022 Ms6.8 Luding) provinces of China, which offers great opportunities to investigate relevant earthquake dynamics, active tectonics, and other related physical processes. Through case studies or statistical analyses, the observations of pre-, co-, and post-seismic phenomena such as ground vibrations, changes in geomagnetic field and geodetic time series, underground water and soil gas perturbations, and fluctuations in the ionosphere can be made. These can be used to better understand Earth processes before, during and after fault rupture, and therefore potentially help forecast earthquakes and their effects. In addition, numerical simulations and AI-assisted methodologies for big data analysis are encouraged to deepen our understanding of these processes.
China is carrying out empirical earthquake forecasting with nationwide observation stations established to monitor earthquake-related information. Some great earthquakes that have recently occurred in mainland China have been forecast in both short and medium-to-long terms. However for other large earthquakes, namely the 2021 Ms7.4 Maduo (Qinghai) earthquake, rupture occurred unexpectedly without pre-cursory indications detected. In this regard, this Research Topic aims to collect the latest Original Research and Review articles on dynamic processes associated with the preparation and occurrence of earthquakes in mainland China, to address (1) what we can learn from these earthquake studies, (2) whether earthquakes can be forecast by empirical methods, (3) whether extant geophysical observations record pre-, co-, and post-seismic processes, and (4) and whether there is detectable coupling between the solid Earth and other spheres such as the atmosphere and ionosphere during the earthquake preparation period and fault rupture process.
Specific themes include, but are not limited to:
• Geophysical methods, techniques, and applications
• Earthquake rupture mechanisms and disaster prevention
• Geodesy and geodynamics
• Deep structure and dynamics of the Earth
• Petrology and geochemistry
• Big data and artificial intelligence
