Latitudinal distribution of earthquakes in the Andes and its peculiarity

Abstract

In the last decade, there has been growing interest in problems related to searching global spatiotemporal regularities in the distribution of seismic events on the Earth. The worldwide catalogs ISC were used for search of spatial and temporal distribution of earthquakes (EQ) in the Pacific part of South America. We extracted all EQ from 1964 to 2004 with Mb>Combining double low line4.0. The total number of events under study is near 30 000. The entire set of events was divided into six magnitude ranges (MR): 4.0 <4.5; 4.5 <5.0; 5.0 <5.5; 5.5 <6.0; 6.0 <6.5; and 6.5 Combining double low line500 km).
