Animation
First of all, to be able to animate correctly, we will collapse the UVW info. To do so, verify that the 2 UVW Mapping Modifiers are below the MeshSmooth modifier, and then right-click on the upper one and choose Collapse To, thus their info will be collapsed in the editable mesh, but will still remain. Activate the Animation mode then select the lower state of the stack Editable mesh and go to sub-object level Vertex.

Goto Frame 100, check that Animate is on and then select the vertices of the 'head' of the explosion, and upper them a bit. Then select then vertices of the bottom of the explosion, but not the one at the base of the central cylinder, and scale them on X and Y axis, this will make the smoke spread. Then play, if the speed seems correct go on, if not, adjust...

Now that the mesh is animated, we will have to animate the fire materials. Since the cellular maps are all set to World XYZ, they won't move as the mesh is deformed, so we have to animate it separately. Go to frame 100 again, and check you're in Animate mode. Now go in your Material editor, and go into each cellular map you have (for each fire/smoke materials you have) and put a value of -30 in Offset Z: , once it's done for each map, make an render of your 100 frames, and look if the fire goes up as fast as the mesh, for nice effect it has to go at least as fast. If not, lower the value in each map again (still in Anim mode) until you've something ok.
Make a render, the Animation is done. (Click below)

The landscape and surroundings around the explosion are mainly up to you, what I can recommend is a worm eye view and a wide fov for your camera, so the explosion looks bigger. The addition of particles is good, but wide smoke particles tend to 'eat' image info and mess up the effects.

Effects are very important for objects like explosion, a glow is very handy to make something look luminous. The effects I chose for this tutorial are :
glow, wide and red, only for the head of the explosion -
glow, sharp and almost white, only for unclamped colors -
blur radial 1% -
blur uniform 0.7 % -
Check the impact of these effects ...
That's it ! The tutorial is over, I hope you got something nice in the end and learned a few things...
Here is a video of what I got in the end. It's DivX 5.02
