Sinking Wastewater Triggers Deeper, Stronger Earthquakes
The effects of pumping wastewater from oil and gas extractions may last a decade or more after the injections stop.
Catching Oklahoma’s Tiny Tremors in the Act
Scientists map thousands of microearthquakes in Oklahoma to take a closer look at the seismic effects of wastewater injection following oil and gas operations.
Fluid Injection Wells Can Have a Wide Seismic Reach
High-volume fluid injection can cumulatively increase underground pore pressure and induce earthquakes in regions unexpectedly far from injection wells, recent Kansas studies show.
River's Rise Linked to Oklahoma's Largest Earthquake
As human-induced earthquakes increase in frequency and magnitude, researchers race to uncover their effects on surface water and groundwater.
