Definition of Longfellow Boom
The Longfellow Boom is a loud, unexplained phenomenon reported in the Longfellow community of Minneapolis, Minnesota, United States. The booms reportedly generally take place on summer nights, and residents have called them "house-shakingly loud" and at a low tone, distinct from a car crash or gunshot. Many who have investigated the booms believe they are caused by several types of unrelated human activities, such as fireworks and improvised explosives being lit in the Mississippi River gorge, trains decoupling, and cars backfiring.
