A minor earthquake with a magnitude of 3.8 struck the Gulf of Maine on January 27, 2025, at 10:22 a.m. Eastern Time. The united states Geological Survey (U.S.G.S.) reported that the tremor occurred approximately 10 miles east of Portsmouth, New Hampshire.
- 3.8-magnitude earthquake in Gulf of Maine
- Occurred 10 miles east of Portsmouth, N.H.
- U.S.G.S. may revise reported magnitude
- Aftershocks can follow initial earthquakes
- Shaking categories based on Modified Mercalli scale
- Data includes quakes within 100 miles radius
The earthquake was initially recorded with a magnitude of 3.9 by U.S.G.S., but this figure has been updated to reflect a more accurate reading of 3.8 after further analysis. Earthquakes in this region are relatively uncommon but can occur due to tectonic activity along fault lines beneath the ocean floor.
Aftershocks often follow an earthquake and can vary in intensity and duration. They typically occur as adjustments along the fault line that experienced movement during the main quake. Aftershocks can happen days to years after the initial event and may even reach magnitudes comparable to or greater than the original quake.
- Initial earthquake magnitude: 3.8
- Location: Gulf of Maine, approximately 10 miles east of Portsmouth, N.H.
- Time: January 27, 2025, at 10:22 a.m. ET
The U.S.G.S. continues to monitor seismic activity in the area and will provide updates if new information becomes available regarding aftershocks or any changes in the reported magnitudes. It is important for residents near coastal areas to remain informed about seismic risks and preparedness measures.
This recent earthquake serves as a reminder of the natural seismic activity that can occur even in less active regions like New England. Authorities encourage residents to be prepared for potential aftershocks and stay updated on safety protocols during such events.
