Dracut ‘earthquake’ turns out to be quarry blast

The US Geological Survey reported this afternoon that it had detected an earthquake in the town of Dracut, but later rescinded the report after realizing it was a quarry blast, state officials said.

The USGS alerted the Massachusetts Emergency Management Agency of a 2.2-magnitude earthquake in Dracut at about 2 p.m., but wrote back thirty minutes later to say it was blasting at a quarry, MEMA spokesman Peter Judge said.
