Abstract :
Recent advances made in forecasting Earthquakes using clustering analysis techniques
are being run by numerical simulations. In this paper, the Gaussian Copula
clustering technique is used to obtain Earthquake patterns such as the Doughnut
Earthquake pattern to better predict medium and large events. Copulas methods
can involve recognizing precursory seismic patterns before a large earthquake
within a specific region occurs. The observed data represent seismic activities situated
around IRAN in the 1980-2014 time intervals. This technique is based on
applying cluster analysis of earthquake patterns to observe and synthetic seismic
catalog. Earthquakes are first classified into different clusters, and then, patterns
are discovered before large earthquakes via Copulas simulation. The results of the
experiments show that recognition rates achieved within this system are much higher
than those achieved only during the feature map is used on the seismic silence and
the Doughnut pattern before large earthquakes
