Residents in the Clayton and Wendell areas reported hearing several loud "booms" that shook their houses between 5:30 and 6 p.m. Sunday.

Emergency officials said fire officials were investigating, but have found no evidence of an explosion that could have caused the loud noises.

Also, officials at both Raleigh Durham International Airport and Seymour Air Force Base said they knew of no aircraft in the area that could have produced sonic booms.
