Earthquake shakes New England
Eyewitnesses across New England experienced an earthquake of moderate size on Tuesday evening. In Boston, there have not been any reports of damage yet.
A moderate earthquake¬†struck the¬†northeastern U.S.¬†state of¬†Maine¬†on Tuesday shortly after 7 p.m. (2300 GMT), according to the U.S. Geological Survey.
First reported as a 4.5 magnitude quake centered near Lake Arrowhead, the USGS revised the quake's magnitude to 4.6 and finally down to 4.0.
It shifted the epicenter to close to¬†Hollis Center, southeast of the original location, and revised the quake's depth from a deep 17 miles (27 km) to a relatively shallow 3 miles (4.8 km).
Hollis Center¬†is about 20 miles (32 km) west of Portland,¬†Maine's most populous city, and about 100 miles (160 km) north of¬†Boston.
Eyewitnesses across the¬†Boston¬†area reported feeling the quake for up to 20 to 30 seconds.
A spokeswoman for the¬†Maine State Police¬†in the Portland area said there were no immediate reports of damage or injuries.
Massachusetts¬†Governor¬†Deval Patrick¬†said state emergency personnel were monitoring the situation but also had no reports of damage.
Quakes are not unknown in the region, which has felt "small earthquakes and suffered damage from infrequent larger ones since colonial times," the USGS said on its website.
