The 911 calls aren't necessarily indicative of an explosive device as she seem to be implying. Just because it sounds like an explosion doesn't mean it's an explosion, especially to initial responders. Think about the difference between shots fired and fireworks.
This witness saw the entire event and per his interview, it doesn't seem like foul play (http://www.youtube.com/watch?v=fweyFCFKcp0).
One valuable insight Krikorian mentions in his article pertaining to the behavior of the recording device:
“That type of surveillance camera has auto exposure so it can change what it sees based by the ambient exposure day or night,” Anderson explained. “This camera is set at night and anything that happens very quickly, be it a flash light or a big ball of fire, the camera won’t react fast enough, so the first flash of light is going to appear much bigger in the viewing. So the initial explosion would always look bigger than it is.”
He suggested a simple demonstration using a cellphone video app: Strike a match in a dark room and it will flare up on camera much more than in reality.

True that. I live near a busy intersection and they closed one lane of a main road that's also a freeway feeder for most of last year while they were upgrading light rail tracks. There were a lot of accidents thanks to the combination of impatient drivers, fewer lanes, and temporary traffic lights in a different position from usual - about one major crash (ie with at least one car on its side) every 6-8 weeks, so I learned more than I wanted to about being first on the scene of an auto accident. A high speed impact makes a hell of a bang just by itself; it's a big, big uncontrolled release of kenetic energy even if there's no fire.

Michael Krikorian (aka, the source of this surveilance video) wrote an article about the whole thing and it tracks closer to the eyewitness's telling of events(http://krikorianwrites.com/blog/2013/7/16/x9pujjqlzq6bbc0kvd...).
