SPATIAL AND TEMPORAL DISTRIBUTION OF GEOPHYSICAL DISASTERS

Analyzing phenomenology, ie. forms of manifestations, consequences, temporal and spatial distribution of geophysical disasters (earthquakes, volcanic eruptions and mass movement dry) around the world, in the period from 1900 to 2013, we have come to the following conclusions: In relation to the total number of natural disasters in the period, which amounted to 25.552, geophysical disasters are in the third place according to its frequency - 11.89%. In the first place are hydrological disasters - 37.40%, and the last are
biological ones - 11.04%. In relation to the total number of people killed in natural disasters, which is
65.009.766, geophysical disasters are in the fourth place - 20.8%. In the first are climatological- 36.57%, biological - 29.46%, hydrological- 21.52% and in the last place are meteorological ones - 4.26%.
In relation to the total number of people injured in natural disasters which is 15.221.227, geophysical disasters are in the first place - 34.01%. The second are climatological- 24.83% then hydrological- 17.44%, meteorological- 17.35% and biological ones - 17:44%. International Conference “Natural Hazards – Links between Science and Practice”  In relation to the total number of people who were made homeless in natural
disasters, which is 337.112.287, geophysical disasters are in third place-13.62%. In the first place are hydrological disasters - 54.94%, meteorological - 31.16%, climatological - 0.27% and, in the end, biological ones 0%. In the period, there occurred 3.037 geophysical disasters, 2.475 of which were earthquakes, 452 volcanic eruptions and 110 mass movements dry. In percentage terms, earthquakes have occurred in 81.49% of cases, volcanic eruptions in 14.88%, and mass movement dry in 3.62%. In geophysical disasters 5.331.007 people have been killed, 5.128.349 of which in earthquakes, 192.624 in volcanic eruptions and 10.034 in the mass movement dry. In geophysical disasters 5.177.147 people have been injured, 5.152.887 of which in earthquakes, 23.238 in volcanic eruptions and 1.022 in mass movements dry; In the period, characteristics of earthquakes were as follows: in Asia it was the largest number: China has experienced the largest number of earthquakes with the largest number of people killed and injured; most earthquakes happened in 1901; in 1976 the earthquakes caused the greatest number of people killed; in 2008 the earthquakes injured most people. In terms of the number and characteristics of consequences of volcanic
eruptions, the following is concluded: most volcanic eruptions were in Asia- Indonesia has experienced the largest number of volcanic eruptions; Martinique had the largest number of people killed, and Colombia the largest number of people injured; most volcanic eruptions occurred in 2006; the most people were killed in 1902; the most people injured in 1985. In terms of the number and characteristics of consequences of mass movement dry, it is clear that they were mostly in Asia; by countries- Canada has experienced the largest number of mass movement dry, in Peru the most people were killed, while there was the largest number of people injured in China. On an annual basis, the total number of earthquakes, volcanic eruptions and mass movements dry until 1970 was average, with some degree of deviation from the annual average of the total observed period, but after that, a serious increase in their number and effects has been observed.
