Report: Don't worry much about quakes and fracking

WASHINGTON (AP) ? A new government report says the controversial practice of hydraulic fracturing does not pose a high risk of triggering earthquakes big enough to feel.

The report said other types of energy-related drilling and wastewater injections do make the ground shake noticeably, but even that's quite rare.

The report is from the National Research Council, which is part of the National Academy of Sciences.

The report said In more than 90 years of monitoring, human activity has been shown to trigger only 154 quakes, most of them moderate or small, and only 60 of them in the United States. That's compared to a global average of about 14,450 earthquakes of magnitude 4.0 or greater every year.
