Residents across parts of Massachusetts and neighbouring New England states reported hearing a loud boom and feeling buildings shake on Saturday afternoon, sparking widespread speculation about the cause.
People from multiple areas across the state, on social media, said they heard what sounded like an explosion shortly after 2 pm (local time) and felt vibrations strong enough to rattle homes and alarm pets.
People from areas including Melrose, Wellesley and Newtonville shared similar accounts with the broadcaster. Some initially believed a tree had struck their house or that a transformer had exploded, while others said the noise was far louder than anything they had previously experienced.
