- When
- 1884
- Where
- Long Island
The 1884 earthquake was probably not associated with the Ramapo fault due to the location of the strongest shaking on Long Island.
The strongest shaking occurred on Long Island, quite far from the trace of the Ramapo fault. Intraplate earthquakes occur when present-day stress is released along zones of weakness in the intraplate crust. The infrequency of seismic events poses problems for researchers unable to firmly associate earthquakes with specific geologic structures without instrumental records.
