What is generally believed to be the first class-action lawsuit against oil and gas companies for causing earthqaukes is working its way through federal courts in Arkansas, according EnergyWire..
The suit stems from numerous quakes as strong as 4.7 that rattled northern Arkansas.
The quakes prompted state officials last summer to ban drilling waste disposal wells in a 1,150-square-mile area. Four wells were shut down.
The people who brought the suits and their attorneys say the companies knew about the risk of earthquakes from their operations but did not do enough to prevent them.
The suits charge the quakes were caused by negligence, amounted to trespassing and created a public nuisance.
The companies named in the suits have denied any responsibility.
Several cases have been consolidated into one case that is scheduled to go to trial in March 2014.
