Residents in areas of Kennebunk, Kennebunkport and Arundel have reported hearing, and feeling, a mystery boom this morning, but no one can seem to pinpoint the cause.
Word of the rumbling, which happened around 10 a.m. Thursday morning, is abuzz on Facebook, with residents in areas of the three towns asking "what was that?" Some have said it sounded like a tree coming down in their yard, others wondered about blasting from area construction, or a clap of thunder.
Kennebunk Police Lt. Eric O'Brien said the department received a number of calls, but police have not determined the source. A dispatcher at the Kennebunkport Police Department also said they did not know where the boom came from, but she likened it to an earthquake.
A representative of the U.S. Geological Survey said that there is no record of any earthquake activity in Kennebunk or southern Maine Thursday morning.
Kate Mastrangelo, who was working in Arundel, said "I don't know how else to explain it other than a boom.
"I could tell it was in the distance somewhere but I could hear it and at the same time the ground shook. It wasn't like an earthquake shake, it just bumped," she said.
Mastrangelo said she immediately thought of the furnace turning on for the first time this year or other equipment in the building, but then thought "no, that was too loud."

Perhaps outgassing from the sea bed caused by this seismic activity had more to do with these deaths than the seaweed that had been lying about on the shore for some time prior to the mass fish kill event?
