Texas quakes man-made, caused by wastewater injections – satellite data

‘Five earthquakes which shook Texas in 2012 and 2013 were caused by wastewater injections during drilling for oil and gas, scientists said after analyzing satellite radar data.
A series of earthquakes struck near the town of Timpson in eastern Texas over the course of a year and a half, with the team of American and British researchers looking into the most powerful of them, which took place in 2012 and reached a magnitude of 4.8.
The researchers used Interferometric Synthetic Aperture Radar, or InSAR, to track the ground movements in the quakes and establish that their causes weren’t natural.’
