Largest ever man-made earthquake? Experts link 5.6 Oklahoma quake which buckled a highway and destroyed 14 homes to oil drilling
A large earthquake, which rocked Oklahoma in 2011 and was felt across 17 states, was caused by oil-drilling, scientists said today.
The 5.6 magnitude quake injured two people, buckled a highway, destroyed 14 properties and was felt for hundreds of miles.
A team of scientists today ruled it was caused by deep injections of waste-water in the drilling of oil – counteracting the view of state seismologists who said it occurred naturally.
If they are right, it is the largest man-made earthquake recorded in the U.S. and will leave many question marks over the practice of disposing of waste-water from oil production underground.
