ELI5: What part of an explosion is the deadly part? The fire, the shock-wave hitting your body, or the shrapnel it creates?

In tons movies and TV shows (Sons of Anarchy being the one that made me think of this) people are killed from explosions, but they are usually far enough away where the heat itself doesn't touch them and they just get thrown in the air about a foot. So what actually killed them? The shock-wave, the blunt force of hitting the ground, shrapnel, or something else?

The shockwave is typically the deadliest force, especially with large explosions. However, the shrapnel will also be quite lethal, and small explosives such as IEDs often incorporate extra metal bits to extend the lethal range beyond that of the shockwave.
