NEW: An "experimental explosion" off the Florida East Coast occurred this afternoon at 3:04 PM. It was large enough to register with a 3.9 magnitude. Historically, this region has been used by the Navy to conduct underwater explosions, including back in 2021. Did you feel it? pic.twitter.com/DrbucYW7Z7
