Shale oil is the cause of earthquakes
One of the main reasons for the increase of the average number of earthquakes in the southern states of the USA is the extraction of shale oil and gas, as said geologists from the University of Texas.

Geologists analyzed data on where and when in the last 100 years, earthquakes have occurred in Texas, and were shocked by the results. a direct relationship has been established between the increase in the volume of shale oil production and an increase in the number of earthquakes in these regions. The dependence appeared in 1925, at the dawn of the industry, the researchers emphasize.

"The public believes that it began in 2008, but it is far from the truth, we would like to think that there is some magical means to solve this problem -. We really wanted to find one or two types of mining operations, which cause earthquakes, and immediately get quiet seismic environment, forcing us to not use them, but in fact its not. "- said the study's lead author Cliff Frohlich (Cliff Frohlich). The results were published in «Seismological Research Letters» magazine. Scientists believe that seismological activity in 59 percent of cases was associated with oil throughout Texas from 1975 to 2015, including the recent earthquake in Irving and Dallas.

It is noteworthy that their study, the researchers started after Texas authorities have repeatedly claimed that there is no connection between the seismic activity and increased production of shale hydrocarbons.
