Frequency of worldwide terroristic acts since the end of sixties
Střeštík, Jaroslav ; Grigoryev, P. ; Mikulecký, M.
The analysis was performed on the eight geopolitical areas (Africa, Eastern Europe, Middle East and Persian Gulf, North America, Central and South America, South-East Asia and Oceania, South Asia, and Western Europe), on their sum and on the solar and geomagnetic variables. There is a good correlation between frequencies of terroristic attacks in different regions. There is also a strong connection between terroristic attacks on one side and some heliogeophysical factors on the other side. All connections are different for different regions and external factors, respectively. Nevertheless, most of them are significant. The relationship to factors describing geomagnetic activity is a little higher than that for factors of solar activity.
