Texas quakes caused by wastewater injections: Study
A series of earthquakes in Texas in 2012 was possibly triggered by wastewater injections while drilling for oil and gas, a new study has suggested. All earthquakes had originated beneath two wells where wastewater generated during oil production was pumped, causing Earth's surface to bulge. The wells reportedly had pumped in over 500 crore litres of water between 2007-2012.
