China’s efforts on the CSEP and a retrospective case Open
China has established a Testing Center on the Collaboration for the Study of Earthquake Prediction (CSEP) for standardized evaluation of current earthquake prediction methods. Some traditional methods such as Load-Unload Response Ratio (LU…

Detecting sub-instability before three <i>M</i> w > 6.0 earthquakes on Chinese mainland in 2020–2022 with load/unload response ratio Open
The sub-instability refers to a stress state that exists between the maximum stress the rock can withstand and its final failure. This stress state should be an indicator of impending large earthquakes, as it occurs in the final stage of e…

Improved medium-to-short-term earthquake predictions in China in 2022 Open
Every year, China should determine annual seismic hazard regions for earthquakes of magnitude 5.0 and above in Mainland China in the next year. Meanwhile, the short-term earthquake potential in each seismic hazard region is evaluated by mo…

The movement and deformation of the Jiangcuo fault before the 2021 MS7.4 Maduo earthquake reflected by GPS and InSAR data Open
The 2021 Maduo MS7.4 earthquake occurred in the Jiangcuo fault with left-lateral strike-slip movement. In order to study the movement and deformation characteristics of the Jiangcuo fault before the Maduo earthquake and further analyze the…

Three-dimensional analysis of air temperature of the Hualien M6.9 earthquake based on the tidal forces Open
The Hualien M6.9 earthquake on September 18, 2022 was calculated based on the additional tectonic stress caused by celestial tidal-generating forces (ATSCTF) model. The period of celestial tidal-generating forces was the time background of…

Propagation of crust deformation anomalies related to the Menyuan MS 6.9 earthquake Open
Decoding the variation laws of the deformation field before strong earthquakes has long been recognized as an essential issue in earthquake predication research. In this paper, the temporal and spatial distribution characteristics of defor…

Correlation between the tilt anomaly on the vertical pendulum at the Songpan station and the 2021 MS7.4 Maduo earthquake in Qinghai province, China Open
Understanding the relationship between precursory deformation anomalies and strong earthquakes is vital for physical earthquake prediction. Six months before the 2021 MS7.4 Maduo earthquake in Qinghai province, China, the vertical pendulum…

Acceleration of Deep Slip Along the Longmenshan Fault Plane Before the 2008 M8.0 Wenchuan Earthquake Open
The first step toward earthquake forecasting is the identification of variables whose spatio-temporal variation can be connected with pre-seismic crustal deformation. Four periods of campaign Global Positioning System (GPS) observations ar…

Stress Field Changes before the <i>M</i><sub>S</sub>8.0 Wenchuan Earthquake Open
The apparent lack of pre-seismic crustal deformation preceding the 2008 Ms8.0 Wenchuan earthquake has been the subject of debate. In this study, tiltmeter data recorded close to the earthquake epicenter were analysed using spectrum and wav…
