“…This, of course, is also related to aspects such as awareness of earthquake hazard prevention and the earthquake resistance of buildings. However, there are studies with different claims, such as the anti-lethal level proposed by Xia et al [14], where the average anti-lethal level was higher in the east of China than in the west. Coseismic landslides are also a major cause of a large number of casualties [41,42].…”

“…How to accurately predict the casualties and economic losses caused by an earthquake and quickly provide post-earthquake emergency response management? Compiling a reliable database of historical earthquake hazard information is both the foundation and the key [14,15]. Based on the database, a series of forecasting models (empirical or analytical) can be established.…”

A comprehensive earthquake hazard database is crucial for comprehending the characteristics of earthquake-related losses and establishing accurate loss prediction models. In this study, we compiled the earthquake events that have caused losses since 1949, and established and shared a database of earthquake hazard information for the Chinese mainland from 1949 to 2021. On this basis, we preliminarily analyzed the spatiotemporal distribution characteristics of 608 earthquake events and the associated losses. The results show the following: (1) The number of earthquakes is generally increasing, with an average of annual occurrence rising from three to twelve, and the rise in the economic losses is not significant. The number of earthquakes occurring in the summer is slightly higher than that in the other three seasons. (2) The average depths of earthquakes within the six blocks display a decreasing trend from west to east, with a majority (63.8%) of earthquakes occurring at depths ranging from 5 to 16 km. (3) Although the number of earthquakes in the east is lower than that in the west, earthquakes in the east are more likely to cause casualties when they have the same epicenter intensity. Southwest China is located in the Circum-Pacific seismic zone where earthquake hazards are highly frequent. The results can provide fundamental data for developing earthquake-related loss prediction models.

This paper reports the use of intensity attenuation equations for the territory of the Northern Tien Shan by modeling the impact of a powerful destructive earthquake of January 22, 2024 in China. The relevance of the study follows from the needed reliable estimates of possible losses due to earthquakes in order to aid the decision making process for the response and the proper choice of a search and rescue strategy for the heavily affected settlements. The paper has as its goal the calibration of the Extremum system models for the territory of the Northern Tien Shan. Our study is the first to analyze the seismic intensity attenuation equations obtained by researchers at different times with a view to their applicability to near real time loss assessment for strong events occurring in the area of study. We investigate how the results of seismic attenuation modeling are affected by the ellipse compression factor k. and the source parameters of a strong event as determined by different seismological agencies in the alert mode. Computer simulation was applied to assess the possible impact of the January 22, 2024 earthquake using the "Extremum" system developed with our participation. This paper provides results of modeling the impact of the 2024 Uqturpan earthquake, as well as an assessment of the convergence achieved by calculated and observed intensities for various intensity prediction equations obtained before for China, Kyrgyzstan and adjacent areas within the Gissar-Kokshaalsky seismically active belt.
