PA earthquake history: See historical map of earthquakes recorded around region

The New Jersey earthquake Friday morning was just the latest of many to be felt in Pennsylvania over the years.

Within Pennsylvania sits the Reading-Lancaster seismic zone, which is responsible for many of those tremors.
