Lexington Avenue explosion

On the morning of March 12, 2014, a massive natural gas explosion leveled two five-story apartment buildings at 1644 and 1646 Lexington Avenue. The blast originated from a fracture in an aging cast-iron gas main beneath the street, which allowed gas to seep into the foundations of the buildings over several days. The destruction killed eight people and injured dozens of others, marking one of the most significant infrastructure failures in the modern history of the city. The incident fundamentally changed how utility companies detect leaks, forcing the implementation of advanced laser detection technology to identify escaping methane before it can accumulate in basement spaces.
