Explosions?

[beanzomatic]

In the first chapter when Michael is at class, is it ever explained what is heard exploding?? Was it something at Raydon Labs? The Beginning of the outbreak?

[ClearSights]

It hasn't been explained yet, most likely will reappear in the future and explain a lot

[daredevil]

Probably just cars blowing up and stuff.

I think the the "Explosions" was actually the crack just discovered by Saul and Victor in the last chapter. It sounded a bit like an Earthquake- ether way, I think the sound was the earth opening up. This also makes me believe that whatever started the zombies is airborne, because it all happened so fast.
