Wastewater Injection Blamed For Increase In US Man-Made Earthquakes

Significant strides in science have been made to better understand potential ground shaking from induced earthquakes, which are earthquakes triggered by man-made practices. Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells. […]

US: Wyden On Earth Day Introduces Clean Energy Bills To Fight Climate Change

As part of his continued work to find new ways to fight climate change while lowering energy prices for US consumers, Senator Ron Wyden, D-Ore.,¬† introduced a pair of bills that would boost domestic clean energy production and reduce carbon emissions. The first, the Geothermal Energy Opportunities (GEO) Act, encourages geothermal energy production by breaking […]

Several natural and man-made factors can influence the subsurface stress regime resulting in earthquakes. Natural ones include intraplate stress changes related to plate tectonics and natural water table or lake level variations caused by changing weather patterns or water drainage patterns over time, or advance or retreat of glaciers. Man-made include human-generated changes to the water table, including dam construction, and industrial activities involving the injection or removal of fluids from the subsurface.

Texas Earthquakes Likely Caused By Combination Of Gas Field Fluid Injection And Removal

A seismology team led by Southern Methodist University (SMU), Dallas, finds that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes occurring near Azle, Texas, from late 2013 through spring 2014. In an area where the seismology team identified two intersecting faults, they […]
