Tuesday evening’s earthquake, centered in southern Maine, has been downgraded to a 4.0 on the Richter scale by the U.S. Geological Survey.

The earthquake, originally reported as a 4.5 and later a 4.6, was centered near Lake Arrowhead, a manmade lake between Hollis and Limerick, or about 30 miles west of Portland. It occurred at 7:12 p.m.

The earthquake was felt in Danvers, as well as many areas of Massachusetts and New England. Gov. Deval Patrick and the Massachusetts Emergency Management Authority both said that no damage or injuries were reported in Massachusetts as a result of the earthquake.

"Residents should use caution if they encounter any damage and take a minute to check in on neighbors, family and friends," Patrick said in a statement released on Tuesday night.
