Where is the faultline in east coast?

The East Coast of the United States does not have a major fault line like those found in the western U.S., but it does have some minor seismic activity related to the ancient geological features of the region. The most significant geological feature is the Appalachian Mountains, which were formed by tectonic activity millions of years ago. Additionally, there are some small faults, such as those in the New Madrid Seismic Zone and the Charleston Seismic Zone, but these are not as active or well-defined as the faults in California. Overall, the East Coast is generally considered to be less seismically active than the West Coast.
