Man-Made Earthquakes: USGS Says Millions in the U.S. at Risk

from Off Grid Survival:

When it comes to preparing for disasters, natural disasters rank at the top of the list of things to prepare for; but one natural disaster has now shifted from the natural category into the list of man-made disasters that could wreak havoc throughout the United States.

According to the U.S. Geological Survey (USGS), millions of Americans, living in areas of the United States that were once thought to be low-risk earthquake zones, are now living in seismic zones that are more active than the high-hazard areas of California.

A federal report from the USGS suggests that some 7 million people in the central and eastern U.S., including people in Oklahoma, Kansas, Texas, Colorado, New Mexico and Arkansas, now live in a man-made earthquake zone. The USGS says that oil and gas drilling can trigger these quakes, and claim many of these areas have seen a dramatic increase in seismic activity over the past six years.

The report comes in response to a dramatic increase in earthquake activity in Oklahoma, which is now one of the most seismic places on the planet.

Beginning in 2009, the frequency of earthquakes in Oklahoma started to skyrocket. From 1978 to 2008, Oklahoma experienced an average of two 3.0+ Mw earthquakes per year. Since then thousands of earthquakes have hit Oklahoma and surrounding areas in southern Kansas and North Texas.

From 2009 – 2013 the rate jumped to 99 M3+ earthquakes per year in Oklahoma. In 2014, there were 659 M3 and larger earthquakes. Last year in 2015 that number jumped to 907 magnitude 3+ earthquakes.
