U.S. Geological Survey – Seven Million People Susceptible to Human-induced Earthquakes

For the first time ever, the USGS has issued maps/forecasts that include the possibility of earthquakes generated by human operations such as wastewater disposal associated with hydraulic fracturing or fracking. The accompanying report expands on this forecast; page 2 of this report states “Earthquake rates have recently increased markedly in multiple areas of the Central and Eastern United States (CEUS), especially since 2010, and scientific studies have linked the majority of this increased activity to wastewater injection in deep disposal wells….” Numerous tables, charts, and references supplement this report. “Induced seismicity” is the phrase used to describe human-made earthquakes; reports and abstracts on USGS research on this topic are available online. Here is an important 2012 report from the National Academies of Sciences – Induced Seismicity Potential in Energy Technologies
