New research reveals that mysterious pockets of earthquake activity in the middle of North America all have one thing in common: Earth’s crust in these zones underwent significant deformation hundreds of millions of years ago, creating weak areas that are more susceptible to earthquakes. These fracturing features could help explain why some regions in central and eastern North America are more seismically active than others....more
