Cuadrilla Caused Earthquakes in the Only UK Fracking
It caused earthquakes up to 2.3 in magnitude that damaged the well casing, which was deformed for 160 feet.1
Sharp Surge in Oklahoma Earthquakes Linked to Fracking
However, many more and much bigger earthquakes have been connected with fracking in the US, where tens of thousands of wells have been drilled and fracked in the last few years.
Fracking produces huge quantities of toxic waste fluid to be disposed of. One disposal method is to inject it into old wells.
A recent study in the highly respected journal Science suggests massive wastewater injection into disposal wells induced a sharp increase in earthquakes in central Oklahoma.
Still, they’d never be allowed to do that near East Yorkshire… would they?
