Scientists with the University of Colorado Boulder and the U.S. Geological Survey are calling for changes in monitoring and addressing human-caused earthquakes.
Over the past 13 years, many parts of the United States that are not earthquake prone have begun experiencing significant quake activity. In Colorado and other states east of the Rocky Mountains, the earthquakes are linked to injection of wastewater from oil and gas production.
The paper, published Feb. 19 in the journal Science, calls for better monitoring of these earthquakes and injection wells linked to such quakes. The ultimate goal is to use such monitoring to change the wastewater injection activities that cause the quakes, reducing risk to humans and property.

Bob Hamilton, director of the Nature Conservancy's Tallgrass Prairie Preserve, has been fighting to block construction of a 68-turbine wind farm.
