Two space time data sets,including earthquakes in north China and SARS in Beijing,are used to application modeling and performance evaluation of MM model.

Centrifuge investigation on effect of seismic history on resistance of sand to liquefaction;

Primary study on the historical earthquakes in Huanhai Sea and its surrounding regions;

In this article, the importance of historical earthquake archives, the work of compiling this archives in the past 50 years in China, and its application in seismic engineering as well as seismic zoning have been introduced.

Taking the northeastern Fujian area as an example, we provide some new technological ideas and contents for the historical earthquake investigation of significant engineering construction sites.

Based on data of historical earthquakes and GPS observation,the authors estimate mean seismic-moment rates and average recurrence intervals of strong earthquakes for the individual segments,and further analyze relative levels of current stress cumulation on the segments based on.

Historical earthquake records show that most historical earthquakes in Anhui area are medium-strong earthquakes,the largest magnitude of them is M614.

This paper describes the basic statistical characteristics of non stationary Poisson process of the events and differences between non stationary and stationary Poisson processes, and applies the non stationary Poisson process to study the long and medium term probabilistic earthquake prediction in North China seismic area.
