SIKESTON -- A billion years ago, nature was ripping the North American continent apart. Then it stopped.

What remained is what geologists call the Mid-continent Rift System.

Today, scientists are using the latest in technology to look deep into the Earth. They are peering some 10 or more miles below the surface to gain a better understanding of the rift and the geology of the continent.

On Tuesday morning, John Powell, a geophysicist and crew chief with Zonge International; and Moira Poje, a geology student and field technician, were in Sikeston, to make their 30th stop in placing equipment as researchers seek data on the New Madrid Fault Line.

the pair placed four electrodes, a magnetic sensor, receiver box and connecting cables.
