NFLUENCE OF GEOPHYSICAL AND SEISMIC FACTORS. ON MORTALITY IN GUSAR DISTRICT

Abstract

The aim of the study was to obtain data on the influence of geophysical and seismic factors on mortality in the
Gusar region.
The study established the relationship between the number of deaths, their causes, distribution by sex and age,
earthquake magnitude, epicenter depth and seismological activity by months. The obtained data were statistically
processed using the Statistica 12.0 for Windows application package (Statsoft Inc., USA). To establish correlation
relationships, Spearman's rank correlation coefficient was calculated, the results were considered reliable at p<0.05.
In the course of the study, 310 case histories were examined in the Gusar region, of which 154 were men (49.7%)
and 156 were women (50.3%).
In the Gusar region, more people died from heart failure among men - 45.9% and women - 54.1%. When comparing
the sexes and the magnitude of the earthquake, more people died with a magnitude of 1.1-2.0 ml among men -
16.9% and 14.7% among women. In the study of the relationship between the causes of death and the depth of the
seismic process, there were more deaths at a process depth of less than 10 km from acute cerebrovascular accident.
During the study, it turned out that more people died on the days of tremors than in the absence, in particular, 167
people died on the days of earthquakes, including 50.9% of men and 49.1% of women, than in the absence of 143,
of which 48.3 % men and 51.7% women.
