Minor Earthquake Rattles Southern New Hampshire
A minor earthquake struck southern New Hampshire at 1:46 PM today, measuring 1.6 on the Richter scale. The quake, originating from a depth of 7.6 km near Greenland, was felt by some residents north of Boston but caused no reported damage or injuries.
According to the U.S. Geological Survey (USGS), earthquakes of magnitude 2.0 or lower are rarely felt, and significant damage typically occurs with magnitudes of 5.5 or greater. While tremors were reported, this recent quake falls well below the threshold for cause for concern, as larger earthquakes striking the region infrequently can produce greater consequences.
New England has a history of small earthquakes alongside infrequent, more damaging events dating back to colonial times. Historically, the region has experienced considerable seismic activity, including damaging quakes in 1638 and 1755, with the last moderate damage event recorded in 1940.
Additionally, a more significant earthquake of magnitude 3.8 was reported along the southeast coast of Maine in January. While it prompted an update from the National Tsunami Warning Center, no tsunami threat was identified.
Residents are reminded that while minor seismic activity is relatively common, larger earthquakes can occur periodically and should not be dismissed. As always, preparedness is key in earthquake-prone regions.
