Underground electrical vault explosion shatters pavement in Hyde Park

An underground electrical vault explosion sent some manhole covers and shattered pavement flying through the air Wednesday afternoon on a South Los Angeles street.

The blast was reported about 3:30 p.m. in the area of Brynhurst Avenue and 63rd Street in the Hyde Park area, according to reports from the scene.

The question is how did this happen?

Kris Larson Batallion Chief LA City Fire said, 'At this time we do not know what the cause of it is, this is a high voltage system, 138 thousand volts, it's currently de energized, they're waiting for authority to go in there and examine it and figure out exactly what the cause is.'

Workers from DWP and SoCal Gas were on scene trying to answer that question.

No one was injured but at least one vehicle was damaged.

The cause of the blast is under investigation.
