New Madrid Airborne Survey
The U.S. Geological Survey is conducting low-level flights across sections of the New Madrid earthquake seismic zone. The USGS will begin conducting the flights tomorrow over a 1,400-square-mile area across southeastern Missouri, northeastern Arkansas and western Tennessee.
Crews will be measuring the earth's magnetic field as well as underground rock formations to help locate concealed faults associated with the zone. The New Madrid area has been the U.S.'s most seismically active region east of the Rockies for decades. The USGS says while there's no evidence of an imminent earthquake, the agency is concerned about the potential for a destructive earthquake like those that occurred in the 1800’s.
