DALLAS (AP) — A university study analyzing a sequence of North Texas earthquakes has found that seismic activity can continue for years even after wastewater injection wells are closed in order to prevent them.

Researchers at Southern Methodist University said this week that high-volume injection near a critically stressed fault can "induce long-lasting seismicity."
