Small Earthquake This Past Week Was Centered In Dedham
Did you feel the earth move this past Friday night in the Dedham area?
The United States Geological Survey tells us that an earthquake with a magnitude of 1.9 happened this past Friday, September 3, at approximately 10:55 p.m. This earthquake was centered almost 5 miles east of Dedham's center, and a little over 9 miles below the earth's surface.
A microquake at 1.9 on the Richter Scale is seldom felt and probably comparable to a large 18-wheel truck, much like what would be seen cruising on Route 1A in that area.
This past Friday's small earthquake was the third such happening in Maine this year.
Other than the one this past Friday night, the most recent happened on Friday, May 21, and was a magnitude of 1.9 as well, centered around Seal Cove on Mount Desert Island. There were a few reports from folks who felt the quake to the Maine Department of Agriculture, Conservation, and Forestry.
The one before that happened on Sunday, January 17, and was a little bigger registering in at 2.8 magnitude. It was centered about 3 miles northwest of the small town of Jonesboro in Washington County.
Since 1977 about 50 earthquakes in Maine have taken place and most have registered below 2.0 magnitude. One of the bigger earthquakes happened in our area back in 2006 under the ocean's waters just east of Mount Desert Island. That one registered at 4.2 and its explosive sound was heard all the way in Ellsworth.
According to an article in the Bangor Daily News the biggest earthquake to ever happen in Maine took place in Eastport in 1904, and it was measured at 5.0 on the scale, collapsing chimneys as far away as Montreal, Quebec.
