Residents are launching mortar sized fireworks from a backyard that are landing on rooftops on Oak Street. Large scale starbursts 50-100 feet in the air that are cascading onto property and trees. It's only a matter of time before a fire results. The noise level is obscene and consistently sounds like exposives are being detonated in the immediate area. Also there was an exceptioally louder explosion earlier that was not a firework, at least not a visibly launched one, possibly a ground detonation in a tube. It was enough to think that the powerplant had exploded again, and made us fearful to approach the windows in neighboring apartments. If this happens again pictures will be provided.
