Abstract:
In view of the scientific problems such as the difficulty of predicting the disaster before the earthquake, the slow and fragmented acquisition of disaster information after the earthquake, the large error of disaster assessment, the lack of decision support and the absence of disaster services, considering comprehensively pre-earthquake emergency preparedness and post-earthquake emergency response scenarios, this research focuses on the information acquisition and analysis methods of full-time disaster and decision-making, real-time convergence and fusion technology of disaster after earthquake, post-earthquake loss comprehensive analysis technique based on the combination of lethality and vulnerability, key points of assistant decision support for different regions, visualization generation technology for multi-user disaster information service product, establishing a disaster situation push and information quasi-real-time service platform and terminals, constructing the intelligent and visual earthquake emergency information whole process service platform based on cloud architecture, and carrying out emergency collaborative service demonstration, to realize the full-time service of disaster information for large earthquakes with magnitude above 7. The project enriches the means of obtaining earthquake disaster information and forms a technical platform of the whole process of earthquake emergency response, including disaster collection, information flash, monitoring and early warning, analysis and evaluation, intelligent coordination and dynamic release. It is of great significance to improve the ability of earthquake emergency information service for quick and scientific rescue.

Abstract:
The peak adjustment of seismic wave is often realized by the method based on the peak ground acceleration (PGA), while the peak acceleration of the design response spectrum in the current specification is the effective peak acceleration (EPA), and EPA is recommended for peak adjustment. Firstly, the meaning and internal relations of PGA and EPA were analyzed, and the existing EPA calculation methods at home and abroad were summarized. According to the different characteristics of bridge structure and building structure, the calculation formula of EPA for bridge structure time history analysis was modified. Secondly, the smoothing processing problem of seismic wave response spectrum in EPA calculation was studied, and three peak smoothing methods were proposed to analyze the value determination of relevant parameter and the advantages and disadvantages of each method. Finally, this method was applied to the time history analysis of a long-span cable-stayed bridge, and the displacement and internal force results of the structure based on PGA and EPA were compared. The results showed that the time history analysis results obtained by the peak adjustment method based on EPA were more reliable.

Abstract:
This paper introduces the main functions, parameter configuration of PRESTo, an Italian real-time earthquake warning software platform. Based on the waveform data recorded during the Yunlong M5.0 earthquake in Yunnan in 2016, PRESTo was tested, and the relevant characteristics of the software were summarized.

Abstract:
Hainan earthquake emergency technology platform is a supporting platform for the technical linkage service of earthquake emergency in Hainan Province, which plays an important role in rapid assessment, command and dispatch in earthquake emergency work. This paper focuses on the analysis of the working ideas and technical design of the upgrading and construction of Hainan earthquake emergency technology platform. Since the platform was put into operation in 2022, Hainan earthquake emergency command center and the earthquake emergency departments of 19 cities (counties) across the province have realized the interconnection within the LAN, data transmission and disaster reporting, and provided the local government departments at all levels with efficient and integrated command and decision-making services in practical work.

Abstract:
On the 50th anniversary of Progress in Earthquake Sciences, the scientific bibliometrics methods supplied by CiteSpace are used to conduct author collaboration network analysis and keyword co-occurrence analysis of the 7151 papers published in Recent Developments in World Seismology from 1979 to 2020. The work aims to systematically explore the thematic context, knowledge evolution, historical hot spots and author group development of the publications of Recent Developments in World Seismology in the different periods. The continuous changes in the theme, advancement of knowledge evolution, and the exchange of historical hot spots showed by papers in Recent Developments in World Seismology fully reflect the past, present and future of seismology. Based on the introduction of scientific communication and the journal publishing model evolution, suggestions such as integrating the scientific resources of the China Earthquake Administration, promoting the intensive publishing, and attracting high-level papers to be initially published in seismic journals are put forward to solve the “multiple, scattered, and weak” problem of seismic journals.
