The magnitude-4.8 earthquake was the strongest in New Jersey in over 200 years.
The United States Geological Survey said in a news conference that more earthquakes are possible, with statistical modelers estimating a 3% chance of an earthquake of magnitude 5 or higher in the coming weeks.
Scientists suspect that the earthquake likely originated in the area of the Ramapo fault zone in the Newark basin. The fault system contains a branching network of faults. Some are mapped but others are probably unknown, so it’s possible that the fault where the Friday quake occurred is unmapped.
This story is developing.
