Satellite-Based Radar Confirms Injection Wells Caused Texas Quakes

Scientists used radar from satellites to show that five Texas earthquakes, one reaching magnitude 4.8, were caused by injections of wastewater in drilling for oil and gas. In 2012 and 2013, earthquakes — five of them considered significant — shook East Texas near Timpson. A team of scientists for the first time were able to track the uplifting ground movements in the earthquake using radar from satellites. A study in the journal Science on Thursday says it confirms that these were not natural, something scientists had previously said was likely using a more traditional analysis.
