The Sharp Rise In Central U.S. Earthquakes Caused By Wastewater Disposal – Study
A new study has indicated that the sharp increase in earthquakes that has been witnessed in central U.S. has been caused wastewater disposal. Just to be exact, the study states that at least 90 percent of all earthquakes in central U.S. are caused by water that has been injected into underground wells. So where exactly do the water come from? Well, according to the study the numerous gas as well as oil companies that are based in central U.S.
The study goes on to point out two things. The first one is the fact that there had recorded an increase in earthquakes that happened within wells that are at least 15 kilometres. Secondly, the study also confirmed that many seismic activities that have been recorded in Oklahoma, one of the states that they were studying, are linked to wells that have huge amounts of water that is salty.
The study goes on to explain why various states in the U.S. have seen an increase in earthquakes that happen in central U.S. If you are to look at the reports then you will notice that, back in 1970’s, the central United States had at least 30 earthquake rates on a yearly basis. The earthquakes were of magnitude 3 and above. Fast forward to 2009 and you will note that the number has significantly increased. As at 2009, the central United States witnessed more than 650 quakes.
The states that were mentioned in the study and were found to be affected include Ohio, Texas as well as Oklahoma and lastly Arkansas.
