The San Bruno pipeline explosion occurred at 6:11 pm PDT on September 9, 2010, in San Bruno, California, when a 30-inch (76 cm) diameter steel natural gas pipeline owned by Pacific Gas & Electric exploded into flames in the Crestmoor residential neighborhood 2 miles (3.2 km) west of San Francisco International Airport[4] near Skyline Boulevard and San Bruno Avenue.[5]
The loud roar and shaking led some residents of the area, first responders, and news media to initially believe that it was an earthquake or that a large airplane had crashed. It took crews nearly an hour to determine it was a gas pipeline explosion.[6]
As of September 29, 2010, the death toll was eight people.[7] The United States Geological Survey registered the explosion and resulting shock wave as a magnitude 1.1 earthquake.[8][9] Eyewitnesses reported the initial blast "shot a fireball more than 1,000 feet (300 m) in the air".[10][11][12][13]
