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.

Were Mexico’s September Quakes Chance or a Chain Reaction?
Last year, two major earthquakes—one 12 days after the first—shook Mexico. New analysis blames this very unlikely event on chance. But one of the pair may have triggered a third large nearby temblor.
