Moderate earthquake strikes Maine, felt in Boston
BOSTON (Reuters) - 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 to a relatively shallow 3 miles. Hollis Center is about 20 miles west of Portland, Maine's most populous city, and about 100 miles north of Boston.
