Explosion Causes Two Buildings To Collapse In Manhattan's East Harlem NeighborhoodFlames and smoke were sent billowing into the air after an explosion leveled two buildings in East Harlem Wednesday, killing two people and injuring more than a dozen others. It happened around 9:15 a.m. on Park Avenue on 116th Street. The exact cause of the blast is still unclear, but Con Edison said crews were responding to the area on a report of a gas odor just prior to the explosion. “The call came in at 9:13 a.m. from a resident who reported smelling gas inside the apartment, but the resident indicated the odor may have been coming from outside the building,” Con Ed spokesman Sydney Alvarez said. “Two Con Edison crews were dispatched at about 9:15 a.m. and arrived just after the explosion occurred.” MORE
