Foci of catastrophic earthquakes on December 26 2004 and March 28 2005 near the island of Sumatra are situated at the extention of the Alpine-Hymalayan mobile belt, which encloses the southern, southwestern regions of Ukraine and the territories of the neighbouring countries. This belt and seismically active zones in the territory of the Easteuropean platform determine seismic hazard of the country and seismic risk of different objects. Analysis of causes and effects of the earthquakes near Sumatra has been made. The main problems are stated based upon the results obtained, which should be solved by Ukrainian seismology in order to diminish seismic risk. Some results of the studies of deep-seated medium structure in the region of appearance of the earthquakes foci on December 26 2004 and March 28 2005 are given as well as results of practical use of records of these events registered by Ukrainian seismic stations in order to refine parameters of seismic hazard (the Chernobyl NPP as an example). <<back |
