This paper reviews the main contents of the following picture book: Guide for travelling in an uncertain world: what is risk? Zhang, J., and Huang, H.W. 2022. Shanghai: Tongji University Press (ISBN: 978-7-5765-0351-7) (in Chinese). This picture book can help children and their parents become aware of risk, learn the knowledge about risk analysis, and cultivate interests related to the science, technology, engineering, and mathematics behind risk analysis. It is a welcome and successful contribution to the education of risk analysis to the child and the public.

It has been observed that, before some strong earthquakes occur, the space static electricity near the ground is abnormal, which might be caused by a large amount of radioactive gas released from the Earth's crust. In this paper, the information diffusion technology for optimally processing small samples is used to analyze 30 cases, and the relationship between magnitude and parameters such as abnormality of space static electricity is constructed. Each case is composed of four observation values: abnormality e, epicenter distance d, impending time t and magnitude m. Using the causal relationship constructed in this paper, the magnitude m of an impending earthquake could be approximately inferred from abnormality e. According to the progress of locking the epicenter and the passage of time, the predicted magnitude could be adjusted in a timely manner. The research results provided in this paper do not eliminate the uncertainty of earthquake occurrence, so that the study is a work of analyzing seismic dynamic risk.Integrating the monitoring information from seismic stations and the physical field information in the air will promote impending earthquake prediction, which is a worldwide scientific challenge.
