The planet will be more separate earthquakes with an increased number of deaths, according to a new study by the U.S. Geological Survey Officer Thomas L. Holzer.
For his analysis, he chose a series of earthquakes, where number Bereaved exceeded 50,000, and the time period to which they relate, began in 1500 AD American geologist saw that as the number of people who have chosen their residence seismically unstable areas, earthquakes with a high fatality also becomes larger.

Computer simulation shows that this century we can expect to have about 17-event of this kind, which is three times more than in the 20th century. Mortality from this type of natural disaster could rise by half if the world population continues to grow relentlessly (3.5 million victims of the 10.1 billion people living on the planet in 2100), and will not pass the proper dissemination of preventive measures and the development of safe housing construction in the densely populated and seismically hazardous locations.
