UD researchers explain why the Virginia-centered earthquake was felt so strongly in Delaware.
According to the DGS based at the University of Delaware, the underground rock formations west of the epicenter (the Appalachian Mountains) as well as underground rocks toward the east are ancient and hard, allowing earthquake energy to travel well. This is in contrast with other areas where there are abundant faults and softer rocks that absorb the energy more quickly. The Delaware Geological Survey also has tracked responses indicating that the quake was felt in many locations from northernmost New Castle County to coastal and inland Sussex County. The Delaware Geological Survey continues to track the earthquake and welcomes more feedback – CLICK HERE for more.
