San Bruno: A massive explosion sent flames roaring through a neighbourhood in the hills south of San Francisco on Thursday, destroying more than 50 homes and leaving at least one person dead.
The utility company that serves the San Francisco Bay area said one of its gas lines ruptured in the vicinity of the blast, which left a giant crater and sent flames tearing across several suburban blocks in San Bruno just after 6 pm.
"If it is ultimately determined that we were responsible for the cause of the incident, we will take accountability," Pacific Gas and Electric Co said in an e-mailed statement.
Flames hot enough to crack a fire engine windshield incinerated 53 homes and damaged 120 as crews continued battling the blaze into the night. At least one person was confirmed dead in the blast, San Bruno Fire Chief Dennis Haag said.
The fire had spread to 10 acres and was 50 percent contained late Thursday, said Jay Allen, spokesman for the California Emergency Management Agency.
Between 150 and 200 firefighters were at the scene, Haag said. More than 100 people were being sheltered at nearby evacuation centres, but no estimate of the number of residents missing was available, he said.
Witnesses said the explosion shot a fireball more than 1,000 feet in the air and sent frightened residents fleeing for safety and rushing to get belongings out of burning homes.
After the blast, flames reached as high as 100 feet as the fire fuelled itself on burning homes. Planes and helicopters flew over the neighbourhood dumping water.
San Bruno Fire Capt Charlie Barringer said the neighbourhood was engulfed by the time firefighters arrived, even though the fire station was only a few blocks away. He said the blast took out the entire water system, forcing firefighters to pump water from more than two miles away.
Haag said firefighters initially had trouble getting close enough to the ruptured gas line to shut it down because of the flames.
