Earthquakes proceed for years after fuel subject wastewater injection stops, examine finds

Shutting down oil and fuel wastewater injection wells might not cease human-induced earthquakes shortly, say seismologists. The scientists analyzed earthquakes at DFW Airport that started in 2008 and located that despite the fact that wastewater injection was halted after a yr, earthquakes continued for not less than seven extra years. They concluded that high-volume injection, even for a short while, can induce long-lasting seismicity when it is close to a critically harassed fault.
