Theory Briefing
- The April 2024 Hunterdon County quake measured magnitude 4.8, making it one of the most felt earthquakes in the region in years.
- Scientists initially pointed to the well-known Ramapo Fault as the culprit, a go-to explanation for seismic activity in the Northeast.
- New research overturns that assumption, finding the quake did not originate from the Ramapo Fault at all.
- The true source structure remains under scrutiny, highlighting how poorly mapped fault systems can be in the eastern United States.
