- Abstract:
-
In order to improve the efficiency of post-earthquake emergency response to global earthquakes(M≥7.0),we design a system for post-earthquake trend analysis of global earthquakes(M≥7.0)based on Python,to quickly produce earthquake related materials.For the same earthquake,different seismic institutions usually give different magnitudes on different scales,and locations are normally different too.To solve this problem,we do the statistical analysis of the historical earthquakes,then propose a rule to determine whether the earthquakes are the same one earthquake,that is,whether the difference of the original time is less than 10 seconds and the positioning error is less than 2 degrees(in radians).According to this rule,we use the crawler technique to obtain earthquake catalogues,focal mechanisms,etc.The system is able to automatically draw the distribution map of the earthquakes through PyGMT module,and output reports on the post-earthquake analysis and forecast in PowerPoint format.The practical application shows that this system could produce post-earthquake trend analysis data,including the distribution of global earthquakes with M 7 or above,historical earthquakes,geological structures,focal mechanism solutions,and statistical relationships with strong earthquakes in the Chinese Mainland,the average running time of the system is within 1 minute which can significantly improve the earthquake emergency response efficiency of global earthquakes with M 7 or above.
