The United States could be causing the increase in the number of earthquakes


The dramatic increase in oil and gas in the United States could be causing the increase in the number of earthquakes in that country.According to the conclusion of an investigation by the U.S. Geological Survey, the number of earthquakes has increased six times. In just three years, increased the number of earthquakes from 50 in 2009 to 134 in 2011.
Experts say some tremors may be caused by the hydraulic fracturing method. This involves injecting a fluid mixture into the ground to cause the release of natural gas, or oil .
