That's exactly it. Not an explosion. Or otherwise that transporter/erector, the tower right beside the rocket would be blown away, it wasn't. Looks like an explosion, right?

The only thing that may count as an explosion, is what happened when the payload hit the ground.
Little consolation though, the pad is devastated, the TE probably also beyond salavage. But the worst is, pinpoint the reason. Before knowing exactly what happened and then make sure it won't happen again, no rocket will fly, from this or another pad. There are plenty of launches planned from Vandenberg, California. The customer is urgently waiting for them to go, but they won't.
